Carbon cranks - what's the benefit?(3 posts)

Carbon cranks - what's the benefit?LauderdaleGuy

I see that Profile and Zipp make a carbon crankset that is very pricey(>$300). Other than reducing some weight, what is the benefit of these? I understand that carbon is useful for reducing road vibration (for fork/wheels), but I don't see how this applies to cranks??

Like just about everything on bikes today, you can pay a lot more for parts that are just a little lighter. Carbon fiber cranks are generally lighter. Unless the manufacturers can also prove that their cranks are just as stiff, there may be a tradeoff.

It is usually good to reduce rotating weight, wheels, pedals, shoes, and to some extent, crank arms, but at what cost? Don't know about road vibration but I think they are stiff enough.
