I'd be real surprised if that setup isn't the most aero for his sprinting position, given my assumption he's been in the specialized wind-tunnel ;)

As amusing as it may seem to criticize Cavendish's fit, it does seem like an odd config all of his previous Specialized bikes have been a 52 (or the rough equivalent in other brands). And if the contact points are the same as a result of stem length and top cap height, aero gains are possibly non-existant. Regardless, his winningest streaks were certainly on a slightly larger frame. He's a small guy, no doubt, but he's not a woman.

Specialized specifically prohibits you from (permanently) running spacers above the stem in their instructions. I think some people keep doing it on a Specialized because they're ignorant or just don't care.

WARNING! Do not permanently place stem spacers above the stem (Fig. 3). Placing spacers above the stem defeats the purpose of the expander plug’s ability to support the steerer tube and stem.

That stem employs a thin shim and a special top cap that is directional based on the shim used such that regular spacers placed atop the stem cause the top cap to no longer sit flush. That specialized stem, thus, requires no spacers atop the stem, permanently.

Some manufacturers do require a spacer atop the stem for warranty purpose. As long as one's expander plug extends to or below the bottom of the stem, all is good.

Haha I saw that image too, and another where he's using the old zipp sprint stem. Who knows, could be a muscle strain or something that will get worked out. I have noticed he tends to adjust that often. I hope he has a good season and bites back at Kittel some.

He is probably just getting old. Rumor has it that he considered riding a Roubaix this year :twisted:

Weird! Could be a million things with the body though. It's funny how people think that part is static with pro riders. Many of them get upwards of 10 even 20 frames a year and won't hesitate to cut and slam a stem fork for one week and have a new one the next with a 1cm spacer. I also find the reverse with a lot of fitting "experts", always proposing a more upright and short position if "you're not a pro" rather than thoroughly analyzing an individual's body, it's potential to adapt. The human part of the equation is the biggest variable and there are too many assumptions in all of the fitting talk.

It's dumb to critique his fit when in actuality all that needs to be said is that the new setup looks* way worse than his old setup.
