BB386EVO? W

[wheelsONfire]

This is what you'd need if you like to skip reducers

http://rotorbike.com/catalog/default/ro ... right.html

It's the width you look for and it's 24mm internally, as your Shimano cranks axle.

It's named BB right because it was made along with Cervelo. But it's really what you look for.

I have the ceramic version, i have used it for gravel, mtb trails and all kinds of dirt.
No problem what so ever.

BTW, you can also replace bearings later on if you want/ need to.

Thanks for all the input!

I think I have found the correct one, theres so many BB out there, and the LBS I have ordered my Cipo Bond frame from say to go PF30, like a CK.

I have found this, which I think is correct for the Bond? Please bare with me. The only BB I have bought are BSA style.

Oh dear. Someone here is confused. You or your LBS I don't know.

PF 30 is not the same as BB386evo as I explained in my earlier post here.

There are several suggestions here for a BB386 BB which is what is specced for a Bond.

That looks like a PF30 model; not what you want.

Unless something has changed, the Bond is a BB386 evo. Wider than PF30:

Nothing has changed, the LBS told me to go with a PF30, as there a better fit, no creaking etc, and then use the reducer cups that come with the Bond.

The Wheels MFG 386EVO will eliminate creaking as it has the thread style fit?

I'm a little concerned as to why your LBS is telling you PF30. Are they saying to just use regular PF30 pressfit bearings and reducers? If they really believe that, then maybe you need a new LBS.

What does "better fit" mean? What would be better than a BB designed for your frame?

Most of the PF30's I see when searching have a centre joining sleeve, that isn't going to work in a BB386 shell.

The Wheels manufacturing BB that you linked to is a fine BB, but is PF30. Did you read the description?

It says "for 68-73 mm frames" (meaning road or MTB PF30).

Your frame is 86 mm wide. Do you see the problem?

Ideally you need a BB386 BB, preferably already Shimano compatible, and preferably IMO, screwed together.

If you don't want to use a reducer, this is an excellent option:

I used the fsa reducers on my vial frame to run dura ace cranks. But that's because the bearings are pressed directly into frame and no other option. I ran it for about a year and never had any problems. Have since switched to a rotor power2max with 30mm spindle.

That said, if given the choice, I'd go with a native bb386 solution that doesn't require adapters. Just less parts moving on down there and less to go wrong.

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

Ditto on that. C-bear is high quality stuff too.

Sorry to piggyback on a thread, but I'm getting an Open U.P. frame which has a BB386EVO bottom bracket, and I've got a BB30 Quarq DZero power meter crankset I want to use with it, can anyone tell me which of these bottom brackets will work for me?

I'm an absolute rookie when it comes to bottom brackets and it's an absolute minefield trying to figure out what goes with what.

Not to bear bad news but bb30 spindles are too narrow to work with bb386. There are a couple threads on this. Bb30 is designed for a shell with internal bearings that is 68mm. Bb386 is designed for 86 mm shell width with internal bearings. You can adapt cranks designed for an 68 mm EXTERNAL bearing system to 386(ie shimano) but generally not a bb 30 spindle.

Then why do Quarq state on their website: "BB30 versions ship with the spacers and wave washer required for BB386EVO installation." ?

Quarq isnt a true BB30, its a one size fits all ie its a long axle bb30, so will fit 386 evo.

Quick cbear search suggests this:

Yes I stand corrected. Their statement is confusing but their "bb30" is actually 386 and ships with the spacers to allow it to be used with 68mm shells. My bad.

Ahh I see, interesting. Thanks!
