hey im wondering if anyone here has a specialized frame with their typical 73mm BB diameter, and if you converted, which is the proper 5 mm shim to flush up that gap with the motor mount? thanks
Many bikes have 73mm bb so that issue is not unique to Specialized frames. I typically use an oversized nut to fit that gap. I think the mounting bolts are 6mm so a 7 or 8mm nut works pretty well.
