SRAM makes their PF30 Bottom Bracket Assembly to fit frames that use this pressfit standard. If your bottom bracket shell has a 46mm ID, then this is the bearing set that you'll need to install your BB30 crankset. Be aware that it will work with any brand of BB30 crank as well. While SRAM's GXP system is proprietary, BB30 is not.

To install this PF30 Bottom Bracket Assembly, you'll want a standard BB30 tool to press the composite cups into the frame and ensure correct installation. The sealed cartridge bearings will ensure smooth operation for many miles. The unit comes complete and ready to install. It's compatible with 68mm road shells and 73mm mountain shells.

Good PF BB-30

  • Familiarity: I've put it through the wringer

It does the job on my BH cross bike. It fit in nicely and is smooth. The BB-30 seems to spin more freely than a 24mm bottom bracket. It has held up through snow, salt, ice, and mud. I clean it up from time to time and I am good to go. I doubt it is worth moving to ceramic, especially since you can afford to replace it more often since it is only $40.
