I have a de rosa SK bike frame, the manufacture says it is bb386 EVO. the inner shell width is 46mm. It is pure carbon with no cups or sleeves or anything. I want to put a shimano ultegra Di2 groupset in this . What bottom bracket can I buy to do this . I don't know a lot about this but i saw an option from wheels mfg. it required the additional purchase of 24mm adapters for shimano. Are there any other options?
Also will this have to be glued in with loctite?
thanks
