Research I've seen (martin) suggests optimal power output is closer to my end of the spectrum. With an aerodynamic advantage, and more comfort,what's not to like? I don't know about you, but I'm trying to go as fast as possible. standard crank length obviously hinders that. Again, speaking from...

actually I got my cranks used, and could easily get my purchase price back. But there is no way I'd sell them. ever. even if I could only own one pair of bicycle cranks. these would be them. When has anyone ever said that crank length is the only way to manipulate performance? Maximizing...

great. you can show me then a cyclist who did not improve with a substantially shorter crank. "and never will" :rolleyes: Well that works out perfect for me, because as a cyclist, I don't want to work with a coach who is uninterested in finding my perfect position and crank length Before...

That's like saying there are ways to improve aerodynamic position other than using tt bars. no ****. But you get bigger reductions in drag, and more power from shortening the cranks and the resulting compact position, and the ability to hold position longer. No reduction in leverage if geared...

From a professional coach no less. Were I being coached by you, I'd be asking for a refund just about now.

yeah, because the relationship between how far the pedal travels and how far the tire travels is meaningless.

30 is a number. Holding an aggressive position is much easier with shorter cranks.

I think you are misunderstanding. "pedal to ground" meaning distance your foot travels vs. distance the rubber on your tire travels across the road. your "view" takes into account no variables. put those same elite riders on shorter cranks with gearing to correct for the gain ratio, and I'm...

"...I conducted a wind tunnel test..."-John Cobb and btw, no one is claiming 30% reduction in frontal area. but the world's foremost authority on aerodynamics in cycling has seen a 30% reduction in "DRAG".

Actually, I'll take John Cobb's stance on aerodynamic positioning over yours. thanks!:)

gain ratio is the gold standard of bike gearing discussion. what we are dealing with is distance the pedal moves vs. distance the entire bike moves. so riding a bike with very short cranks in a very easy gear ratio can have the same gain ratio as a bike with standard cranks in a standard gear...

Now imagine there may be a simple cheap equipment change that could even further improve his 5min power at the same fitness level!

I've never had bad back pain, but occasional soreness. Nevertheless, I too found it more comfortable in the new more aggressive short crank position. At first I thought it was because of the hip angle. But now, I think it is because it allows your pelvis to roll forward without thigh/rib...

I think he's saying overall there is a wattage drop going into the " rather extreme aero position" that short cranks can't overcome (though he can squeeze out another 5).

so, if I'm understanding you correctly. In an aero position you make more power on 148mm cranks. But overall you made the most power in a more upright position. Did you test the shorter cranks in a more upright position? After the cyclocross season is done, I will be testing my wattage at...
