Anyone know of anyway to put a 30mm axel on a bb86 frame? Everything I am seeing is only for 24mm cranks. I see the problem is a 42mm outer diameter bearing for bb30 cranks and a 41mm inner diameter for bb86 sleeves. Frame is the Scott Plasma Premium and Crank is the Zipp Vumaquad. Thanks

been a few threads on this recently, search. It requires a 4mm bearing that you would need to find. Also requires a longer spindle.

Already searched the forums and not an option, everyone says find this bearing but there is simply no 30mm id 41mm od by 4mm bearing that is made for this. I have looked at boca bearings and vx bearings and called fairwheel, and a few LBS and Hardware stores and no dice, was just wondering if anyone has figured out a solution or found this mystery bearing.

I've already done the searches and drew the same blank. The other problem that makes it difficult to fit is the axle width. The BB86 standard has a 86.5mm width BB shell, vs the BB30 68mm shell, so true BB30 cranks (non-spacer) like a Rotor 3D+ won't be able to fit even if a 41mmx30mm bearing was theoretically available.

I ordered an RXRS Di2 frame, thinking it would be like a BB30 RXRS non-Di2 frame, and cannot use the 3D+ crank. The BB86 system is non reversible, only 24/25mm axle crank systems can be used, due to the standard bearing selection, and the 86.5mm width. You could use a 30x37mm bearing, with a 2mm shim ring or bushing to enlarge the OD to 41mm, but that doesn't solve the width fitting.

ID 30, OD 37, width 4mm. They are $60 each at boca bearings. You'll need to make a cup to fit the bearing to the shell though.

And at 4mm, they are about half the width of a normal Bottom bracket bearing so you might want to double up. so you are looking at $240 in bearings alone

Bumping up this thread, I want to fit a 30mm crank to my BB86 Scott Foil and I stopped to this:
1) FSA K-Force Light BB386 EVO
https://www.bike24.com/1.php?content=8&product=82574;
2) FSA Bottom Bracket Adaptor for BB386 EVO Crankset on BB86
https://www.bike24.com/1.php?content=8&product=114179

Is there anybody running a 30mm crank to their BB86 frame? And if so, what did you choose for BB, is this reliable ?

Correct, there are several solutions (but all based on the same idea I think...), these 2 are a little harder to get in Europe I believe.
What I'm interested more is to hear some experiences from someone who actually used this :roll:

Just get new cranks...seriously. I've been through this going from a SRAM/Quary PM with BB30 frame in the past, and moving to PF86...just sold the other PM/Cranks, bought a used PF86/SRAM version, then got the PF86 Wheels Mfg ceramic bearings, and I've used their angular. Much simpler...but requires buying/selling. Sadly that is the problem with moving to a different frame/mfg setup, good chance you just screwed your BB/Crank and maybe PM setup.

Otherwise, using those other adapters is a rig and requires spacers and other things which really the system ends up adding complexity to the setup. Just my two cents, give it a whirl though and let us know how it works out if you think some adapter offered will work out well.

Well, this is, I don't really want to be the guinea pig as I'm not so rich to afford trying if it would work fine or not... :)

I suspect most of the problems will be down to the piddling size of the bearings.

Yes it works. I had this setup on my trek crockett. If you have the new 4 arm spider crank design and a correct associated bottom bracket there will be no issues. If you do not have the new 4 arm crank, you need to check the spindle and ensure that it says "BB 86 Compatible" lazer etched into the spindle. I had the "older" 386 crank (2013ish) and it was not BB86 compatible.

At this moment I don't have the crankset or the BB, I just have the frameset, so if I will go with FSA (or Rotor) on 30mm I will buy the latest version which I suspect it's compatible...

Yes, this would be, but I'm wondering how much impact, I would expect that the lifetime to be shorter and I could live with a 1/2 lifetime for example, but I don't want to change the bearings every 2 months...
