Road crank question from an MTBer.

[Globalti]

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?

172.5s should be right for you for a road bike. Depending on what you wish to do 175s would also suit, if you are used to longer cranks.

NB, don't mix makes of kit, especially the intimate parts like cranks and BB. Oil and water springs to mind.
