I am currently building a bike around the Focus Izalco Max frame (PF30 bottom bracket, carbon frame) and would like to use the carbon cranks from my Specialized Roubaix SL3 Pro (2013) if possible. The Specialized bottom bracket is OSBB and the spindle diameter is 30mm.
I’ve tried to fit the crank into the PF30, but the cups of the PF30 that protrude from the frame make it just a little too wide. So I was wondering if there was any solution to this? Some kind of adaptor special PF30 fitting?
As an aside, I’m aiming for a light build so if there is a lightest solution
Thanks in advance!
