EXI PF30 Bottom Bracket

What Our Gearhead® Experts Are Saying:

"This is my go-to when converting a PF30 frame to a Shimano or Race Face 24mm crank. Installation is straightforward, the cups seat cleanly, and the wide bearing stance helps prevent creaks. It’s a reliable, workshop-friendly option."

The Race Face EXI PressFit 30 Bottom Bracket is designed to solve one of the most common compatibility challenges in modern bike builds: pairing PF30 frames with 24mm spindle cranksets. By adapting the 46mm PF30 shell to work seamlessly with Race Face EXI, Shimano Hollowtech II, and select FSA MegaExo cranks, it gives riders flexibility without compromising drivetrain performance.

Unlike traditional internal press-fit designs, the EXI system places the bearings externally, similar to threaded external mountain bottom brackets. This wider bearing spacing improves load distribution and durability while reducing the likelihood of creaks under power. CNC-machined and anodized aluminum cups ensure precise tolerances and a stable interface with the frame.
