After upgrading my Cannondale Flash with a set of Hollowgram cranks, I am building a Pivot Mach 429 as my primary ride. I want to swap over the drivetrain to the new frame. Is there a way to use my BB30 crankset in the BB92 frame?

 

[Nater]

Nope, the hole isn't big enough.

 

[Fix the Spade]

Nope.

BB92 frames can only fit the Shimano/Raceface press fit size. There is no way to adapt them to accept any other size of bb or spindle, so you need new cranks I'm afraid.

 

[SByota]

That's what I was afraid of. The hollowgrams are so nice though.

Is there not a conversino bottom bracket that will let you run a BB30 crankset in a BB92 frame?

Nope. The spindle on a BB30 crankset is too large (30mm) to fit through the hole in a BB92 BB shell and still have room for bearings. The spindle size on a crankset that is compatible with a BB92 is 24mm.

You can go the otherway though...run a 24mm spindle crankset in a frame with a BB30 shell.

Not sure

I have a 2010 SRAM XX 2X10 crankset. I originally installed it on a 2008 Specialized Sworks using the BB30 bottom bracket. I sold the Sworks and bought a 2012 Scott 29er frame which has a BB92 shell. I bought the BB92 SRAM press fit bearings for the frame and used my SRAM XX crankset, had it installed by my LBS, and everything fit without modification and it works great. What are you guys talking about?

Sounds like your crank is a GXP, not a BB30. You can not put a 30mm spindle (BB30) in a 23/24mm hole (SRAM PF92 GXP BB)

:madman:Then why does e thirteen offer a pf92 bottom bracket for their bb30 cranks. I wonder if this would work

eThirteen cranks use a 30mm spindle but are not BB30 spec cranks.

Bearing spacing for BB92 and the e13 is wider than BB30.

I believe you can use the Cdale cranks (at least the crank arms). The Cdale mtb spindle length is something like 132mm. The rub is that the spindle has a flange on one side.

If you swap out the spindle to an aftermarket flange-less version:
BSA bottem bracket for SI Alu MTB crankset - Dr. Cannondale

and an E-13 30mm dia BB92 cup you should be good to go.

Good luck

Some help. I have a SRAM GXP BB92 that I want to replace the bearings on. What size bearings should I get? I just need new bearings not a new BB.

GXP is Gigapipe External, so you should have outboard bearings running on your 30mm spindle. This sounds suspect though, because GXP is usually a thread-in-to-BSA 24mm system.
