Carbon Crank use?(3 posts)

Carbon Crank use?Proboscis

Anybody have any experience(s) with carbon cranks. Are they really that much stiffer? Or would I not feel that much difference against my Dura ace 7700's with my 165lbs? Thinking about switching my 170mm arms for 175mm arms for my tri bike. Thanks.

I have the FSA carbon cranks, and I am getting ready to purchase the new Campy Record carbon crank. I don't really feel any difference. The difference is in the weight and the look. I spoke with the FSA rep, and he spoke of all sorts of studies about stiffness and strongness. I can't tell the difference. They do look cool though. I am going to sell my FSA cranks which have about seven months use on them if you are interested.

Odds are great that you won't be able to tell the difference. Even with a difference in stiffness the less stiff crank would act as a spring (i.e. energy storage device) and you'd get virtually all of it back. The one thing you will notice is that your wallet will be lighter, so you _may_ be a tad faster up hills...;-)

Why aren't you interested in using the current "standard" roadie 172.5 mm crank arm length? Seems like your going from the short to the long side of things. Expect some aches and pains as your lower body makes the adjustment.

Ask yourself what you're trying to achieve - is it perfomrance, weight, or some fashion statement.
