Bb386?
 
Does anyone know which FSA BB is used in a bb386 frame? Can't find a specific BB listed on their site for a BB386.

I used this one, but there is also a non ceramic version

The BB386 is a press fit assembly that has the diameter of the BB30 and the width of a 68 mm BB shell with screw in cups installed. Just guessing that the BB parts are just bearing cartridges like BB30. Since the shell is wider though, you have to use a long spindle crank like on a threaded BB with outboard cups. FSA makes the BB386EVO crank for this purpose.

Let me clarify a bit and define what BB386 is.
BB386 has a 86mm wide shell. BB30 bearings are used but here is the important thing...BB386 uses a 'standard PF30 BB'...any standard PF30 BB will work OP. All BB386 is....is a 86mm wide version of 68mm wide PF30...bearings/bushings are wider apart. As a result, BB386 uses a 30mm spindle diameter however has similar length to an external threaded BB. The type of crank that will work for BB386 is somewhat evolving into a defacto standard because such a crank can be used on everything from an English threaded BB to BB/PF30 to wider shell BB386. More narrow shell PF30 simply uses spacers on each side to take up the longer spindle length.

I am just bumping this to the top to give others the opportunity to dispute it. Afterall, this the 41 and that which is wrong is right. So what I wrote even though correct is certainly fair fodder for ill founded criticism by those insulted by the truth.
