I use an FSA 386EVO crankset with a 386EVO frame. I can strongly recommend BBInfinite bottom brackets. They use a one piece design that is supposed to eliminate issues with alignment. I have had issues with some other brands, namely clicking sounds and improper wear of the crank spindle. The BBInfinite bottom bracket has worked like a charm.

Wheels Manufacturing outboard bb that threads into itself? Has lips on both sides, so no way it can come loose..unlike BBinfinite

Just installed a new Wheels Mfg BB86 to replace a crappy pressfit SRAM version. I've had used them previously, but now the BB actually is threaded and screws into itself.

Way better than the press fit I had which I used loctite to secure it and deal with creaking.

I just had someone hold the frame securely while in the mech stand, and I hammer the crap out of the old one, first side with a screw driver, it popped out finally. Then used a socket/extension to get it flush against the other side still in the frame loctited in. Popped with with a few good whacks. No heating, and the old BB came right out. Just used some sand paper lightly to get it nice/smooth. Then greased the frame/bearing, used 1 wrench to install it. Once one side was secured and against the frame, I just screwed the other side with the wrench, and the other side never ever budged/turned at all, torqued it within reason, perfect. Smart design and resolves the creaking issue I would assume since the threaded connection keeps it secure in the BB.

For $99 for the angular steel contact bearings, really nice and smart design. For double you can get the ceramic version. Highly recommend it.
