No, I will have only 31 cm from bb to hub, so the chain will not run smoothly. > Could you explain the A >= B thingy? See the attachment, when the pedal is pushed there will be a resulting force (green) which wants to push the bb to the right side. It is like a seesaw. hub is the center of rotation, the pivot with the body acts as counterforce. When A = B then the forces are balanced, if A > B then it is even better. Greetings Jürgen Maier
