TF-i know there's a chickie in Perth who has a mtb with short cranks & will try and catch up with her on them. I believe we'd be talking 170mm cranks.

Oak-I'm not experiencing pain or stiffness any longer though? It's one small movement that's holding me back from mtn biking & powering down out of the saddle on the road bike

When i was in Canuckland & did a short spin on a spin bike @ a gym & I could make a complete circle then. What type of cranks are on most spin bikes?

thanks
