Re: Crank arm length from fit perspective [zinny]

Thanks for the thorough answer findinfreestyle. From LAI's response, I figure he had a negative or at least not beneficial experience from going "short". Which I haven't really considered.

So with that thought, while the majority of the examples seem to be people "over cranking". Are there any of people "under cranking" and its affects? Could that negatively affect fit?

Yes there can be a negative effect with going too short. You could go too short where replicating your same fit is impossible, extremely difficult, or just unsafe (stability). There is also gearing to take into consideration. You will spin out your gearing quicker on downhills.

Edit: Another negative could be aerodynamics. You have to keep on raising your saddle as you go shorter on crank length. There will be a point in which your cda will increase when you go shorter cranks and raise the saddle. This is probably the extreme though and would take a huge step to change this. (Eg 200 to 130)
