Unless you can draft someone who starts half way around the track from you aero is important for things like pursuit.

Carbon in particular can be 'tuned' directionally through the fibre layout for torsional stiffness and vertical compliance, providing an extremely comfortable while stiff ride.

I figured that was the case with steel/aluminum.

As for the carbon, that makes sense with multi-directional carbon (like cranks, and the higher end frames), but that doesn't explain much for carbon tubing. Or is there something I'm misunderstanding here?

Also, what this means is, carbon might be good for the road, where long saddle times and non-ideal road conditions might make riding uncomfortable, but on the track it's really just for bling factor?

As a side note, let's keep the scalpels away from Jose R, lest he starts getting ideas.

the truth is--and this really is the truth, what matters is heart and lungs and legs. again, lance (say) could win on most anything with properly inflated tires. it ain't a cliche--it's not about the bike, it's about the rider. :) :beer:

Last time I checked trackraces were won and lost on differences of 3 inches on a regular basis. 3 inches at 40 mph is the sort of difference bike design can give you.

right, but what if some scientist were to make an exact duplicate of lance and give them different bikes? there would be a small difference, but it would make the guy with the better bike have better odds.

I read somewhere that given scientific training and nutrition, humans have reached close to their peaks in most sports, and there will likely be fewer and fewer world records broken as time goes by. That may be one of the reasons why gear is so important to elite-level sports, especially a sport like track cycling.

that's a good point. kinda sad though to me that it's come down to that. ugly, over-engineered stuff. it's still fun to watch though. :) :)

they don't have to be ugly, im sure a nice colognalo style paint job would do it some wonders. and ive seen carbon pursuit frames lighter and more aerodynamic than that

In MYHO, these kind of frames only look good (and of any real benefit) on geared bikes on the road. Anyways, what is the benefit of carbon on track bikes ridden on the velodrome? To absorb road shock from bumps? What bumps? Can anyone here explain this?
