I want to change the cranks on my training bike, they are Campy cranks on a Jap BB and so the chainline is all wrong. Also the RH crank is bent, somebody off C+ sold me them for a few quid years ago. My question: looking on Eblag, most of the cranks on sale are 170mm. Is this appropriate for somebody 6' with a 32" inside leg? My current cranks are 175mm and we get along just fine as I'm just not tuned into the nuances of road bike setup. Lastly, anybody got any old Jap taper 175mm road cranks they want to flog?
