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 bottombracket 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

I just bought a chinese open mould frame and I went through this bullshit. I bought a BBinfinite BB86 bottom bracket and it works great so far. I'm also using di2.

Here's the bb386evo: https://www.bbinfinite.com/products/bb386evo-directfit-shimano

There's enough room for the di2 cables to pass through the bottom bracket.

Also, they specify loctite 609 or 641.
