This is an interesting technical presentation from Cervelo, discussing the importance of bike weight and bike aerodynamics. I hope the link works on your PC, otherwise check here, „Col de la Tipping Point.“
The company’s conclusion in a nutshell:
„Let’s look at the 2007 Etape du Tour, held on one of the toughest stages of the Tour. Our model predicts a time of 8h00m35s (including turns, stops and group riding) for the aero bike. This is 35 sec faster than the light bike with the same 250W rider – despite the very hilly course.“
My conclusion:
„At the average 30 minute duration JCRC race, a better bike would bring an advantage of 2 to 3 seconds. This will probably not be enough to close the two minute gap between myself and the second last rider (unless, Stephen Coady attends).“
Still, I love my Cervelo. As I loved my Cannondale.
