I need to tap into your knowledge chaps.

I am buying a Bond frameset this weekend, and it uses a BB386EVO bottom bracket, 24mm for DA9100 crank.

My current bike uses a BSA style, which is great quick and easy, and Cermaic too, so spins effortlessly.

I have been looking at Rotor 386EVO, which I think uses Enduro bearings. Is there anything else out there that I can use? The demo bike I had the pleasure of using, had a rather draggy BB!

Do Shimano have a 386EVO

Shimano doesn't supply a BB386 BB but C-bear does. It's an all-in-one solution so no adapters (shims).

https://www.c-bear.com/en/products/bott ... e-face-fsa

C-bear BB's are ceramic, you can order them directly from them by sending them an email. Very fast delivery, worldwide.

You would need BB386evo insert with 24mm bearings to accommodate Shimano crank.
You cannot go wrong with threaded together aluminium cups, for instance Wheelsmfg, different bearing options available, ceramic (hybrid) too.

PS
Just to avoid further confusion
insert = bottom bracket

Inserts = recipe for disaster.

Always use "real" solution like C-bear or Wheelsmfg.

Thanks for the fast replies!

The BB that I think I would buy is this Rotor....

The Rotor is pressfit. C-Bear also.

A threaded solution is an alternative like this http://wheelsmfg.com/bottom-brackets/bb386evo/386evo-bottom-brackets/386evo-angular-contact-bb-for-24mm-shimano-cranks-black.html

BB386 is really just a wide PF30. The PF30 standard has looser tolerances than BB30 and was designed to use delrin cups to house the bearings. The idea being that delrin had some "give" to accommodate variations in shell diameter.

So the inherent problem when pressing metal cups into a PF30 or BB386 frame is some installs will be tighter than others. Which is where the threaded solutions may have an advantage.

You should also look into the ease of install, removal, and bearing replacement with the various brands and what tooling is needed.

Whats wrong with using the standard evo bearings and a pair of fsa 30-24mm reducers?
Its what my XR2 runs on and zero problems.

I also found Token making a screwed-together BB386 Shimano size BB https://www.tokenproducts.com/bottom-brackets/mountain/ninja-bottom-bracket

If you haven't already ordered, I've had less than satisfactory bearing life with Rotor BBs. I'd look at Wheels MFG.

The Wheels link I posted says that it's "fall 2017" for availability.

I've always been OK with Token products, so if it was me, I might try theirs. Available now http://www.ebay.com/itm/Token-Thread-Fit-Press-Fit-Ninja-Bottom-Bracket-for-24mm-Axle-/122593605814?var=&hash=item1c8b25f8b6:m:mOKm1a0RL8fIRi8Erf2tb7g

+1 This is the setup I use on my De Rosa without any issue so far. Dead silent BB and smooth turning crank set.

Anecdotal evidence, but it's an inexpensive solution so might be worth a try.

The problem is that you're adding "parts" which can (will?) eventually create problems.

There's no more parts added to potentially cause problems than with any of the other solutions suggested.

And a poorly fitted screw together type is just as likely to creak etc as an incorrectly fitted standard 386evo bb.

Depending on if you're planning on using a crank based powermeter (eg in my case P2m S type) , some of the screw together options won't give you enough clearance.
