Lies - Plain and Simple

PeeweeescapesI sure wish I could ride faster

S-LANDISTOUR9243It's easy, just pour water on your head


Well who knew? Apparently you can win the Tour de France simply by drinking water and pouring some over your head. This news is going to turn the athletic world upside down.

Saris Cycling Group, the makers of the Powertap bike computer has published THIS ARTICLE entitled, "Water, Plain and Simple", written by "Dr." Allen Lim that doesn't simply postulate, imply or otherwise suggest that Floyd Landis won the Tour de France with water; the article 'confirms' that water was the miracle drug that Landis used on his amazing and superhuman Stage 17 ride.

Lim begins by saying that Landis' power output that day was well within what Landis was capable of and what he had done on previous training rides so there is no need to think that performance enhancing drugs had anything to do with it. So let's begin there too, shall we? First off, Lim is a paid endorser of Saris' Powertap and has been for a few years now. Did you get that? Paid endorser. You pay, he'll say whatever you want him to say. So you need to understand that whenever Lim opens his mouth what comes out is an advertisement or some other crap designed to convince you to buy a Powertap. OK, with that out in the open let's examine Lim's comments regarding how Landis can maintain whatever wattage for whatever period of time. Lim notes that Landis had maintained higher power on prior training rides than he did on his miracle ride. The point he attempts to make is that the ride really wasn't miraculous at all - just a normal training ride for Landis. Of course we can't know what the actual power numbers were. We simply have to trust Allen Lim and his data. But even if they are real, so what? Any suggestion that because Landis' power output during a Tour ride matches that of a training ride somehow proves that Landis didn't take drugs is stupid. Hey Lim, maybe Landis was on drugs during his training rides too.

After all of the garbage regarding power output Lim then goes on to suggest that by drinking lots of water and pouring even more over his head, Landis could easily ride away from 135 of the best cyclists on the planet. Lim states that because Landis had a Powertap during Stage 17 he could watch the wattage numbers and see that whenever he poured a bottle of cold water over his head his power output went up. Lim states, "Because of the direct and immediate feedback from the power meter, Floyd came to an immediate and extraordinarily important realization during his ride -- that every time he poured ice cold water on his body, his power output went up". Whoa, Nelly! Can you believe this? During a critical moment in the Tour a discovery of such magnitude is first discovered? Never in all of the years of cycling, the millions of people riding bikes, the billions of miles ridden on bicycles over the course of history no one ever figured out that pouring water over your head could turn you into Superman. It took Floyd Landis in a desperate situation to make this amazing discovery. Thank God he had his Powertap along with him!

Lim concludes his article with two more nuggets;

1) Pouring water over Floyd's head is, "such an extraordinary advantage that it's hard to conceive of any drug that could give him such a boost. It was water, plain and simple, not testosterone that was responsible for his incredible ride."

2) Pouring water over Floyd's head had such a huge impact that, "Floyd asked me not to mention it in my daily reports, as he wanted to keep the significance of that advantage as his own".

OK, number 1 - Pouring water over your head is more powerful than testosterone or any other performance enhancing drug? Who is he kidding? I've never heard such an asinine statement made from anyone, let alone a 'scientist'. Why would any athlete subject himself to the risks of illicit drugs if all it takes is a glass of ice water? And I'm just taking a stab in the dark here - but hasn't anyone ever poured water over his head in an athletic event before? Surely someone would have noticed this immediate and extraordinary boost in power. I once poured a glass of ice cold water over my head during the run leg of a triathlon, and still finished well off the back. What has your experience been? More akin to mine than to Landis', I'm sure.

And as for #2 - What a boatload of stinking crap! Again, people pour water over their heads in races all of the time. If this was such a performance booster surely we would have figured it out before this year's Tour. So I can't imagine an actual scenario where "Dr." Lim and Floyd had an actual conversation about this super secret. But if I could imagine it, it would go something like this;

Landis: Holy crap! Did you see my power output?
Lim: I sure did. It was amazing. Where did that come from?
Landis: It was the water.
Lim: Water? What was in it?
Landis: No, just plain water. Every time I poured some on my head I felt like Superman! It was incredible!
Lim: You mean that just by pouring water on your head you could ride faster?
Landis: Yes. Isn't that amazing?
Lim: Wow! Wait until I tell my friends.
Landis: Hold on a second. We can't let anyone know about this. I'll be using this secret to win race after race. Lance and his seven Tours? Ha! I'll win ten in a row!
Lim: But I'd really like to write about this. You know, like a scientific paper or something.
Landis: No way! Not until I retire from racing. You have to promise - you won't tell anyone.
Lim: OK, I promise.

But of course the funniest part is that Lim tells us how Landis asked him not to mention it and then it becomes the cornerstone of Lim's silly article about the miracle of water. He's telling everyone!

This whole Landis affair has turned lots of people into liars.

It's amazing how similar Floyd and Pee Wee look after pouring water over their heads.

Review: Specialized Transition Expert

Elvisexpert1  026

The Specialized Transition Expert is Specialized's mid-line time trial bike. The S-Works bikes sit atop of Specialized's line and other, lesser grade Transition models are below. All of Specialized's time trial/triathlon frames are essentially the same with the componentry mixture setting the bikes apart. Here are the components as delivered on the stock bike;

FRAME: Specialized E5 AEROTEC, fully manipulated aero tubing, compact Transition design, internal brake and derailleur guides, replaceable derailleur hanger
FORK: Specialized FACT carbon aero Transition Speed Zertz, carbon legs, crown, and threadless steerer
HEADSET: Specialized Mindset Plus, 1 1/8" integrated threadless, sealed stainless steel cartridge bearings, carbon 20mm cone with two 5mm alloy spacers
STEM: Specialized Pro-Set lightweight stem, 3D forged alloy, 4-bolt 31.8mm bar clamp, 4- position adjustable
HANDLEBARS: Specialized Zertz Transition bullhorn bars, 31.8 clamp, with Profile Designs Carbon Stryke aero bars
TAPE: Body Geometry, cork ribbon
FRONT BRAKE: Shimano Ultegra
REAR BRAKE: Shimano Ultegra
BRAKE LEVERS: Tektro RX4.1 aero levers
FRONT DERAILLEUR: Shimano Ultegra, 31.8mm clamp, bottom pull
REAR DERAILLEUR: Shimano Ultegra, short cage
SHIFT LEVERS: Shimano Dura-Ace, 10-speed bar con shifters
CASSETTE: Shimano Ultegra, 12-25t
CHAIN: Shimano Ultegra, 10-speed
CRANKSET: FSA SLK MegaExo, 2-piece carbon crankset
CHAINRINGS: 53x39T
BOTTOM BRACKET: FSA integrated, exterior cartridge bearings, alloy
RIMS: Mavic Cosmic Elite
FRONT HUB: Mavic Cosmic Elite, 18 hole, Mavic QR
REAR HUB: Mavic Cosmic Elite, 20 hole, Mavic QR
SPOKES: Stainless 14g aero
SADDLE: Body Geometry Transition Pro saddle, microfiber cover, full nose padding, cro-mo rails
SEAT POST: Specialized Transition carbon, aero seatpost with Speed Zertz
SEAT BINDER: Specialized CNC, alloy

Since I didn't need the Mavic Cosmic Elite wheels I sold them on ebay ($330.00) and slapped on the Mavic Kysrium SL's that I already had. I also put on a pair of Speedplay pedals from my rolling stock. I paid $1600.00 for the complete bike. This represents a good discount off of the $2400.00 list price and my dealer explained to me that Specialized was in a hurry to dump the 2006 line of aluminum time trial bikes because the 2007 frames will be made out of carbon fiber. This is a trade secret so please don't tell anyone. I don't really care. After selling the wheels I have a really nice TT bike for under $1300.00.

_____________________________________________________________________________________________________

FRAME

The frame is made from aluminum. Specialized likes to impress you by calling it Aerotec E5 Alloy. The "E5 Alloy" comes from the fact that Specialized's aluminum is a blend of 5 different elements. No customer can understand the significance of this, if any. It's just marketing B.S. for aluminum. Aluminum is stiff and light and can be shaped easily, all pluses for a time trail frame. The downtube, seat tube and seat stays are all designed to provide an aerodynamic advantage, that's the "AEROTEC" piece.


Here is what the Specialized marketing people wanted you to read about this frame;

"The Specialized-designed Transition triathlon frame found on the Elite, Comp, and S-works models represents the best in modern aluminum manipulation technology. Our engineering department designed this ultra light race frame to have an extremely low drag coefficient, by radically butting, swaging, and shaping each tube to be optimized for aerodynamics and ride quality.

The NACA-designed elliptical downtube and seatstays are proven to reduce drag and deliver true aerodynamic performance. The aero downtube is an angled ellipse shape for minimum drag, but tapers to an oval for maximum stiffness at the BB junction. This unprecedented attention to shape manipulation sets new standards in weight, BB stiffness, aerodynamics, and ride quality.

Our engineering and technical prowess has been combined with Iron Man-winning geometry, designed with guidance from Tri legend Peter Reid, balancing rider position, center of gravity, and wheelbase. The headtube angle was slightly relaxed, the fork rake increased, and the trail increased to give the rider more stability at speeds. The chainstays were shortened, and the front-center was increased to keep the rider's weight centered over the bike for additional stability. The seat tube angle is 76 degrees for forward-biased weight placement, and the head tube is shorter to allow the rider to attain the critical aero position. Even details like our unique internal cable routing add to the aero advantage."

Elvisexpert5  030

As a primer on bicycle aerodynamics it's important to understand that for any aero advantage at all, the depth of the object that is hitting the wind must be at least twice the dimension of the width, or frontal area. A 2:1 ratio. At this ratio and above the wind turbulence is lessened, reducing drag. Let's take the Transition's seatpost as an example;

Elvisexpert3  028Elvisexpert2  027

The post on this bike is 1" wide and 2" deep. Even though a quick glance seems to indicate that the post is extremely aerodynamic it just meets the minimum 2:1 ratio. The forks, downtube, seat tube and seat stays all have ratios higher than 2:1. The aero seat stays are pretty snappy looking, too. This frame does in fact offer an aerodynamic advantage over traditional frames. Score one for Specialized. To read more about aerodynamics and bicycles see HERE.

Elvisexpert4  029Elvisexpert7  032

For even more aerodynamic advantage the brake and derailleur cables are routed into and out of the frame, so-called, "internal routing". No lengthy cables catching the wind. Although I think that the cables near the front of a bike catch more wind that those that run along the top and down tubes. Still, I suppose it's a feature.

Elvisexpert6  031

Note in the picture below how the downtube goes from thin and aero to thick and beefy (note also the exits for the cabling);

Elvisexpert8  033


More important than profile and weight in frame design are dimension and geometry. That's because a rider's position on a time trial bike is much more important than the bike itself. The rider must be low, narrow and most importantly, comfortably positioned to be able to generate maximum power over time. Before dropping the cash on a TT bike I recommend that you take numerous test rides with a set of allen wrenches. Ride, adjust, ride adjust. When you find a bike that allows you to feel comfortable and powerful you'll know it. Don't listen to the sales-guy telling you how great and aero you look, or how flat your back is. If you feel good and fast and your chest is still open enough for proper breathing you've probably found an adequate bike. That being said, most TT bikes that you might buy today offer enough adjustments to get your body where it needs to be. A frame's seatube angle of 76 degrees sounds great, but proper saddle tilt, height and fore/aft are much more important. Don't get caught up in specs. Specs make for good reading, "feel" makes for good riding.

______________________________________________________________________________________________________


COMFORT

To get a rider comfortable on the Transition, Specialized offers a variety of nifty items. The fork, seatpost, Profile Design aero handlebars and FSA crank are all made of carbon which can dampen road shock and buzz. The handlebar tape is thick cork ribbon which can also absorb road buzz. The Specialized Body Geometry Transition Pro Saddle (whew!) is designed to both reduce pressure on your naughty parts at the rear of the saddle, as well as offer padding up front. Padding up front is important because when in the tuck position more of your weight will be forward on the saddle. Specialized also makes a very big deal about their Zertz technology. Zertz is another fancy marketing word. These Zertz things are basically bits of rubber that are wrapped around the fork legs, seatpost and handlebars. Since road buzz begins at the road/tire interface and moves up the frame to the rider, Zertz are placed between the road and the rider and supposedly absorb some of the buzz. Click HERE to read more of the marketing bla, bla, bla about Zertz technology. Keeping in mind that 'Zertz' sounds a lot cooler than 'rubber bands'.

Elvisexpert9  034Elvisexpert10  035

Zertz rubber band Lots of adjustability and padding. Zertz band at bottom of photo

Finally, the cockpit design will allow riders of all shapes and sizes to find a comfy position. The arm rests are almost infinitely adjustable; fore/aft, up/down angle, side-to-side angle, and width can all be adjusted. The rest pads are thick and firm. The bullhorn bars can be twisted up and down. The aero bars move, in relation to the bars/pads; fore/aft, up/down, narrow/wide and can twist in or out. It will take a while to get all of these adjusted just right, but when you get there it will have been worth all of the trouble.

Elvisexpert11  036Elvisexpert12  037

The final piece of gear that adds to your comfort are the bull horn bars. Look at the picture above, right. See how the bar flattens a bit under the arm pads? The rounded section of the outboard portion of the bars flatten towards the inboard area. This gives you lots of places to grip the handlebars that vary the pressure points. You'll have no excuses for getting numb hands or fingers.

All of these adjustments are to meet one single goal; comfortable aerodynamics. Aerodynamics is the most critical aspect of cycling speed but you must be comfortable in an aerodynamic position for anything longer than a 10 mile ride. I've included some links at the end of this review that you can read to learn more about aerodynamic positioning.

__________________________________________________________________________________________________________

EQUIPMENT

As you can see from the parts list above, Shimano Ultegra stuff is featured. Ultegra offers most of the advantages and features of Shimano's top of the line Dura-Ace stuff. Weight, fit and finish are not quite to Dura-Ace standards but the price is significantly lower. I found the brakes to be every bit as good as the Dura-Ace stuff that I'm used too but we'll see how long it stays that way. One nice thing about Dura-Ace is it's durability and longevity. I think that the positioning of the brake levers at the end of the bullhorn bars makes it easier to apply pressure than when the levers are on the curve of normal road handlebars. That might be why the Ultegra brakes felt just like Dura-Ace.

Shifting with Ultegra was much stiffer and louder than with Dura-Ace but not so much as to detract from the overall feel of this bike. I don't ask much from the drivetrain (front deailleur, rear derailleur, chain, cassette), get me from one gear to the next without any trouble - the Ultegra stuff does it's job.

I've never ridden with carbon fiber cranks and the FSA SLK MegaExo are a nice introduction. Like Ultegra, they are not FSA's top shelf cranks but they offer most features of the expensive stuff; stiffness and light weight. They also use a two piece crank with exterior cartridge bearings which offer increased life and even load bearing. I don't detect any arm flex, and the carbon arms, in addition to looking cool, may be absorbing some road buzz.

The Zertz handlebars are light and comfortable but I would change the stem. It's just a heavy block of aluminum. Lots of inexpensive and lightweight carbon stems are available. The Tektro brake levers offer great feel and are easy to modulate, which is probably why I could compare the Ultegra brakes so favorably. The Profile Designs Stryke handlebars were very comfortable when I finally got them adjusted to the correct position, along with the arm rests. And the Dura-Ave bar end shifters are quick and accurate.

Specialized use their own proprietary integrated Mindset Plus headset. I would much prefer to be able to replace them with a Chris King headset, but I'll just have to live with it.

All in all a very nicely equipped bike. Since I can't change the headset the stem is the only thing that I will consider replacing.

__________________________________________________________________________________________________________

RIDE

Each time I take this bike for a spin I'm favorably impressed with how it feels so light, stiff and fast. In cruise mode I can run two gears higher than normal. I had to stop a number of times during the initial rides to make micro adjustments to the cockpit and the saddle. You really need to ride a few miles, as opposed to riding around the dealer's parking lot, to get a good feel for a bike. Once the position was dialed in I made a point of riding through varied terrain so that I could test it out on flats, uphills, downhills and on twisty roads. Other than the steepest uphill sections I found that I could stay in the tuck position quite comfortably and was able to generate plenty of power on all roads.

I found that the multitude of available hand positions can make a long ride seem shorter because I was comfortable and relaxed. In the tuck position you can grab the bar extensions high or low, out far or in close. And the multi-shaped bull horn bars offer lots of grip points. It did take a while to get used to the bar end shifters. I found myself trying to push the brake levers inwards for shifting.

The fit and finish are remarkable for a bike at this pricepoint. I don't trust any bike dealer to properly set-up bikes and this one was no different. I needed to tighten the stuff bolted onto carbon (dealers appear to be afraid to over-tighten and therefore leave things a bit loose), and the stuff bolted onto aluminum was too tight. After those adjustments the bike exhibits no rattles, squeaks or other noises that lessor bicycles can make. The bike feels very tight and well put together. I can put it best this way; it felt very much like a $2400.00 bike. It's list price.

The Transition Expert offers a very smooth ride. Neither twitchy nor sluggish. One thing I do notice is that there is very little buzz on the pedals. Is this due to the Zertz stuff throughout the bike? Is it the carbon crankset (this is my first carbon crank)? Or is it that in the tuck position some of your weight is shifted off of your feet and onto the saddle and handlebars? I suspect it's the latter but in any event the ride is remarkably smooth and comfortable.

The fork, being aero, has more carbon fiber material than what you find on most road bikes. This additional carbon fiber allows the fork to absorb lots of road buzz and shock. The front end of this bike is extremely comfortable. Even on rough roads you will be able to maintain your aero position and apply power evenly.

I do note that direction changes require more input than what my Colnago requires, but that's probably not a fair comparison given that the Colnago's list price is about three times that of this bike. On fast downhills the Colnago really shines with picking a line and then sticking to it as if on rails. This Specialized does not have this quality and requires more attention. Certainly not enough attention to classify it as sluggish, just not as refined as the Colnago.

Even a short spin on the bike will confirm the stiffness and lightness of it's aluminum frame. Some parts of the frame may be thin and aero, but the bottom bracket and headtube junctions are beefy, minimizing frame flex during out of the saddle accelerations or when grinding uphill. I've detected no frame flex whatsoever. The lack of flex in the bottom bracket and headtube make this bike feel lighter than it is. All applied power goes to forward motion. A terrific trait for a time trial bike.

The saddle is very cushy compared to the Fizik that I usually ride and I've never been a fan of anything but firm saddles. However, this Specialized model has me convinced that for time trials a cushy saddle is the way to go. Bent over in a tuck position puts a lot of pressure on a very small area at the front of your pelvis. Ride like this for an hour on a firm saddle and you'll be looking for a Viagra prescription. But this cushy saddle effectively spreads the contact area out a bit and really adds to the overall comfort of this bike's ride. Do you lose some efficiency with a less than firm saddle? Probably. But you gain it back in spades by being comfortable for a longer period of time.

At 18.8 pounds as I have it set up it's not by any means a bike for you weigh weenies out there. But keep in mind that a light weight bike is not that important when it comes to time trials or triathlons. Getting up to speed and maintaining it with comfort and power is. As I mentioned earlier, finding a bike that fits you like a glove while putting you into an aero position is the goal with any TT bike.

__________________________________________________________________________________________________

OVERALL AND RATING

Overall I find the Specialized Transition Expert to be a high quality time trail bike at it's price. I find no significant compromises on frame build or equipment selection. It's extremely comfortable when properly set up and is light enough for hilly courses. I did swap out the stock wheels and have heard that they are heavy and a bit sluggish so check them out if you plan to use them on this bike. The bike is stiff and fast. Isn't that what we are all looking for in a time trail/triathlon bike?

"The Specialized-designed Transition triathlon frame found on the Elite, Comp, and S-works models represents the best in modern aluminum manipulation technology. Our engineering department designed this ultra light race frame to have an extremely low drag coefficient, by radically butting, swaging, and shaping each tube to be optimized for aerodynamics and ride quality.

The NACA-designed elliptical downtube and seatstays are proven to reduce drag and deliver true aerodynamic performance. The aero downtube is an angled ellipse shape for minimum drag, but tapers to an oval for maximum stiffness at the BB junction. This unprecedented attention to shape manipulation sets new standards in weight, BB stiffness, aerodynamics, and ride quality.

Our engineering and technical prowess has been combined with Iron Man-winning geometry, designed with guidance from Tri legend Peter Reid, balancing rider position, center of gravity, and wheelbase. The headtube angle was slightly relaxed, the fork rake increased, and the trail increased to give the rider more stability at speeds. The chainstays were shortened, and the front-center was increased to keep the rider's weight centered over the bike for additional stability. The seat tube angle is 76 degrees for forward-biased weight placement, and the head tube is shorter to allow the rider to attain the critical aero position. Even details like our unique internal cable routing add to the aero advantage."

As a primer on bicycle aerodynamics it's important to understand that for any aero advantage at all, the depth of the object that is hitting the wind must be at least twice the dimension of the width, or frontal area. A 2:1 ratio. At this ratio and above the wind turbulence is lessened, reducing drag. Let's take the Transition's seatpost as an example;

Elvisexpert3  028Elvisexpert2  027

The post on this bike is 1" wide and 2" deep. Even though a quick glance seems to indicate that the post is extremely aerodynamic it just meets the minimum 2:1 ratio. The forks, downtube, seat tube and seat stays all have ratios higher than 2:1. The aero seat stays are pretty snappy looking, too. This frame does in fact offer an aerodynamic advantage over traditional frames. Score one for Specialized. To read more about aerodynamics and bicycles see HERE.

For even more aerodynamic advantage the brake and derailleur cables are routed into and out of the frame, so-called, "internal routing". No lengthy cables catching the wind. Although I think that the cables near the front of a bike catch more wind that those that run along the top and down tubes. Still, I suppose it's a feature.

Note in the picture below how the downtube goes from thin and aero to thick and beefy (note also the exits for the cabling);

More important than profile and weight in frame design are dimension and geometry. That's because a rider's position on a time trial bike is much more important than the bike itself. The rider must be low, narrow and most importantly, comfortably positioned to be able to generate maximum power over time. Before dropping the cash on a TT bike I recommend that you take numerous test rides with a set of allen wrenches. Ride, adjust, ride adjust. When you find a bike that allows you to feel comfortable and powerful you'll know it. Don't listen to the sales-guy telling you how great and aero you look, or how flat your back is. If you feel good and fast and your chest is still open enough for proper breathing you've probably found an adequate bike. That being said, most TT bikes that you might buy today offer enough adjustments to get your body where it needs to be. A frame's seatube angle of 76 degrees sounds great, but proper saddle tilt, height and fore/aft are much more important. Don't get caught up in specs. Specs make for good reading, "feel" makes for good riding.

COMFORT

To get a rider comfortable on the Transition, Specialized offers a variety of nifty items. The fork, seatpost, Profile Design aero handlebars and FSA crank are all made of carbon which can dampen road shock and buzz. The handlebar tape is thick cork ribbon which can also absorb road buzz. The Specialized Body Geometry Transition Pro Saddle (whew!) is designed to both reduce pressure on your naughty parts at the rear of the saddle, as well as offer padding up front. Padding up front is important because when in the tuck position more of your weight will be forward on the saddle. Specialized also makes a very big deal about their Zertz technology. Zertz is another fancy marketing word. These Zertz things are basically bits of rubber that are wrapped around the fork legs, seatpost and handlebars. Since road buzz begins at the road/tire interface and moves up the frame to the rider, Zertz are placed between the road and the rider and supposedly absorb some of the buzz. Click HERE to read more of the marketing bla, bla, bla about Zertz technology. Keeping in mind that 'Zertz' sounds a lot cooler than 'rubber bands'.

Finally, the cockpit design will allow riders of all shapes and sizes to find a comfy position. The arm rests are almost infinitely adjustable; fore/aft, up/down angle, side-to-side angle, and width can all be adjusted. The rest pads are thick and firm. The bullhorn bars can be twisted up and down. The aero bars move, in relation to the bars/pads; fore/aft, up/down, narrow/wide and can twist in or out. It will take a while to get all of these adjusted just right, but when you get there it will have been worth all of the trouble.

Elvisexpert11  036Elvisexpert12  037

The final piece of gear that adds to your comfort are the bull horn bars. Look at the picture above, right. See how the bar flattens a bit under the arm pads? The rounded section of the outboard portion of the bars flatten towards the inboard area. This gives you lots of places to grip the handlebars that vary the pressure points. You'll have no excuses for getting numb hands or fingers.

All of these adjustments are to meet one single goal; comfortable aerodynamics. Aerodynamics is the most critical aspect of cycling speed but you must be comfortable in an aerodynamic position for anything longer than a 10 mile ride. I've included some links at the end of this review that you can read to learn more about aerodynamic positioning.

EQUIPMENT

As you can see from the parts list above, Shimano Ultegra stuff is featured. Ultegra offers most of the advantages and features of Shimano's top of the line Dura-Ace stuff. Weight, fit and finish are not quite to Dura-Ace standards but the price is significantly lower. I found the brakes to be every bit as good as the Dura-Ace stuff that I'm used too but we'll see how long it stays that way. One nice thing about Dura-Ace is it's durability and longevity. I think that the positioning of the brake levers at the end of the bullhorn bars makes it easier to apply pressure than when the levers are on the curve of normal road handlebars. That might be why the Ultegra brakes felt just like Dura-Ace.

Shifting with Ultegra was much stiffer and louder than with Dura-Ace but not so much as to detract from the overall feel of this bike. I don't ask much from the drivetrain (front deailleur, rear derailleur, chain, cassette), get me from one gear to the next without any trouble - the Ultegra stuff does it's job.

I've never ridden with carbon fiber cranks and the FSA SLK MegaExo are a nice introduction. Like Ultegra, they are not FSA's top shelf cranks but they offer most features of the expensive stuff; stiffness and light weight. They also use a two piece crank with exterior cartridge bearings which offer increased life and even load bearing. I don't detect any arm flex, and the carbon arms, in addition to looking cool, may be absorbing some road buzz.

The Zertz handlebars are light and comfortable but I would change the stem. It's just a heavy block of aluminum. Lots of inexpensive and lightweight carbon stems are available. The Tektro brake levers offer great feel and are easy to modulate, which is probably why I could compare the Ultegra brakes so favorably. The Profile Designs Stryke handlebars were very comfortable when I finally got them adjusted to the correct position, along with the arm rests. And the Dura-Ave bar end shifters are quick and accurate.

Specialized use their own proprietary integrated Mindset Plus headset. I would much prefer to be able to replace them with a Chris King headset, but I'll just have to live with it.

All in all a very nicely equipped bike. Since I can't change the headset the stem is the only thing that I will consider replacing.

RIDE

Each time I take this bike for a spin I'm favorably impressed with how it feels so light, stiff and fast. In cruise mode I can run two gears higher than normal. I had to stop a number of times during the initial rides to make micro adjustments to the cockpit and the saddle. You really need to ride a few miles, as opposed to riding around the dealer's parking lot, to get a good feel for a bike. Once the position was dialed in I made a point of riding through varied terrain so that I could test it out on flats, uphills, downhills and on twisty roads. Other than the steepest uphill sections I found that I could stay in the tuck position quite comfortably and was able to generate plenty of power on all roads.

I found that the multitude of available hand positions can make a long ride seem shorter because I was comfortable and relaxed. In the tuck position you can grab the bar extensions high or low, out far or in close. And the multi-shaped bull horn bars offer lots of grip points. It did take a while to get used to the bar end shifters. I found myself trying to push the brake levers inwards for shifting.

The fit and finish are remarkable for a bike at this pricepoint. I don't trust any bike dealer to properly set-up bikes and this one was no different. I needed to tighten the stuff bolted onto carbon (dealers appear to be afraid to over-tighten and therefore leave things a bit loose), and the stuff bolted onto aluminum was too tight. After those adjustments the bike exhibits no rattles, squeaks or other noises that lessor bicycles can make. The bike feels very tight and well put together. I can put it best this way; it felt very much like a $2400.00 bike. It's list price.

The Transition Expert offers a very smooth ride. Neither twitchy nor sluggish. One thing I do notice is that there is very little buzz on the pedals. Is this due to the Zertz stuff throughout the bike? Is it the carbon crankset (this is my first carbon crank)? Or is it that in the tuck position some of your weight is shifted off of your feet and onto the saddle and handlebars? I suspect it's the latter but in any event the ride is remarkably smooth and comfortable.

The fork, being aero, has more carbon fiber material than what you find on most road bikes. This additional carbon fiber allows the fork to absorb lots of road buzz and shock. The front end of this bike is extremely comfortable. Even on rough roads you will be able to maintain your aero position and apply power evenly.

I do note that direction changes require more input than what my Colnago requires, but that's probably not a fair comparison given that the Colnago's list price is about three times that of this bike. On fast downhills the Colnago really shines with picking a line and then sticking to it as if on rails. This Specialized does not have this quality and requires more attention. Certainly not enough attention to classify it as sluggish, just not as refined as the Colnago.

Even a short spin on the bike will confirm the stiffness and lightness of it's aluminum frame. Some parts of the frame may be thin and aero, but the bottom bracket and headtube junctions are beefy, minimizing frame flex during out of the saddle accelerations or when grinding uphill. I've detected no frame flex whatsoever. The lack of flex in the bottom bracket and headtube make this bike feel lighter than it is. All applied power goes to forward motion. A terrific trait for a time trial bike.

The saddle is very cushy compared to the Fizik that I usually ride and I've never been a fan of anything but firm saddles. However, this Specialized model has me convinced that for time trials a cushy saddle is the way to go. Bent over in a tuck position puts a lot of pressure on a very small area at the front of your pelvis. Ride like this for an hour on a firm saddle and you'll be looking for a Viagra prescription. But this cushy saddle effectively spreads the contact area out a bit and really adds to the overall comfort of this bike's ride. Do you lose some efficiency with a less than firm saddle? Probably. But you gain it back in spades by being comfortable for a longer period of time.

At 18.8 pounds as I have it set up it's not by any means a bike for you weigh weenies out there. But keep in mind that a light weight bike is not that important when it comes to time trials or triathlons. Getting up to speed and maintaining it with comfort and power is. As I mentioned earlier, finding a bike that fits you like a glove while putting you into an aero position is the goal with any TT bike.

OVERALL AND RATING

Overall I find the Specialized Transition Expert to be a high quality time trail bike at it's price. I find no significant compromises on frame build or equipment selection. It's extremely comfortable when properly set up and is light enough for hilly courses. I did swap out the stock wheels and have heard that they are heavy and a bit sluggish so check them out if you plan to use them on this bike. The bike is stiff and fast. Isn't that what we are all looking for in a time trail/triathlon bike?

Elvis' Playlist



sixteenth

People will often say to me; Elvis, what kind of music do you listen to? What are your favorite songs? I really can't answer that question. I love all kinds of music. Classical, rock, jazz, country, big band, electronic, alternative, blues, folk, showtunes, metal. Even the odd rap or polka tune can strike my fancy once in a while. I'd say that I even like fusion, but I don't know what it is.

But I can tell you what is on my iPod playlist at the present time. Warning note to cubicle dwellers; music will automatically begin playing if you click some of the links to the artist's websites. Turn your sound down so that The Man doesn't learn that you've been surfing the web on company time.

Jacket That You Never Wore –
Joe Sibol
An excellent example of how independent artists shame the mainstream, pre-packaged, distributed and vertically marketed crap that fills today’s radio waves. Joe writes and sings his own songs for the love of music. Compare his vocals to that of any American Idol and tell me if talent matters in today’s world.

Love Me Like You – The Magic Numbers
I can’t remember where I ran into this brother-sister group from the U.K. Doesn’t matter. It’s a fun, upbeat and catchy tune.

Pin a Rose On Me – Chuck Prophet
Heard this on NPR’s World Café. See, even some of us who lean to the right listen to NPR. I’m not sure how to classify this guy but he’s got a unique voice that slides musically up and down throughout the song. Good deck music for a late evening chai.

Sunshine Superman – Donovan
Take a groovy trip, baby! A classic example of the 60’s psychedelic style. What do the lyrics mean? I guess you need to be in a drug-induced haze to figure them out. They might call him mellow yellow but this is easily Donovan’s best song.

Get Ready – The Blenders
An a cappella group from Fargo, North Dakota, covering a Temptations song. What else do I need to say? Except to point out that the vocalized drum break to end the song is pretty cool.

Keep the Customer Satisfied – Simon & Garfunkel
For all of us that are involved in sales in some form or another (And really, that would be all of us, wouldn’t it?). Great brass throughout this classic from 1970. This song was somewhat lost on the album that included; Bridge Over Troubled Water, The Boxer, Cecilia and El Condor Pasa. So why do we all know the lyrics?

Sun is Shining – Funkstar Deluxe
A remix of a Bob Marley hit. I dislike Bob Marley music. I love this song. My brain hurts if I think about that too much.

Fine Line – (Sir) Paul McCartney
A nice song from McCartney’s 20th post-Beatle album. You can take your Bono’s, Mick’s and Bruce’s, for my money, Sir Paul sits alone at the top of modern music, and has been there for 40+ years. If you ever get a chance to see him perform live, do it. For heavens sake, the guy was a Beatle.

Wild Week-End – NRBQ (New Rhythm and Blues Quartet)
If you’re not familiar with NRBQ look them up. There is a lot of good stuff in their collection. I like this song because it harkens the beach with it’s bluesy guitar riffs. Come on, Annette, let’s dance! Surf’s up, dude!

Channel Z – The B52’s
From the group that brought us Rock Lobster and Love Shack - so it’s got the familiar up-beat, funky sound. And you gotta love Fred Schneider’s vocals.

The Captain of Her Heart – Double
I’m feeling up the cantaloupes at Piggly Wiggly, looking for a nice, ripe sample when I hear this song drifting softly from the overhead sound system. Hadn’t heard this in years but after hearing it I couldn’t get it out of my head for days. I didn’t like the song when it came out in 1986, now I love it. Funny how much things can change in 20 years. Double was one-hit wonder from Switzerland. Name another one.

Eli’s Coming – Maynard Ferguson
I was in the jazz band in high school (trombone) and Maynard Ferguson was a favorite jazz artist for his jazz-rock blends and his hard hitting brass section. This song is the best example of Maynard’s style; calm opening sequence, moving to the full band build-up with a couple of instrument solos, and finally to Maynard’s screaming trumpet. Ahhh! Brassy jazz just doesn’t get any better than this. And a Three Dog Night cover to boot!
