New Crankset..which bottom bracket?
 

Sorry for the noob question.


I bought a used Rotor 3D+ NoQ 52/36 110 170 crankset from a guy on craigslist.

I have a Masi Evo 2013 di2 bike that I got few years ago. It currently has a "FSA PressFit with Adapters". Not sure what that means. Can anyone tell me what bottom bracket I need? I know rotor has their own brackets, but they have a few different models.

Thanks

I would call or email Rotor. They should know. Roger

Just looked up a review and all through the review it said it was BB30 but then in the specifications they said it was PF30. Since you say it is pressfit, I would assume the PF30 is correct.

You will need to know what diameter the spindle is - looks like they are available in both 30 and 24 mm.

AFAICT, that frame is a PF30 BB spec. So if your Rotor crank is a 24mm spindle, it works with adapters such as Praxis or WM in the BB. If it's 30mm spindle, then any PF30 BB should work (suggest WM "screw together" PF30 BB to prevent creaks). I assume the Masi is a 68mm shell width, so if the cranks are designed for wider shell (BBright or BB386), then you might need spacers and might have to check chainline.
