Crank Length ?

Didn’t Cook Bros make their RSR in both 170 and 171? .. the temperature variation between a hot and a cold day would make those differences

My first foray into short cranks was completely accidental, about 20 years ago I bought a Hobbs of Barbican and gave it a bit of a refurb. The williams cranks were 6 1/2", I remember thinking they seemed different to my other bikes but enjoyed using them. Fast forward to creaky knee years and I tried short cranks again and there really is no going back for me
