Rolling deep
The PF30 bottom bracket uses reliable 6806 retainer bearings packed with waterproof grease, along with wiper seals to keep the gunk out.

Close Enough Won’t Cut It
We fired up the ol’ CNC machine to make sure the anodized 30mm alloy cups of this bottom bracket provide an exact, perfectly quiet fit for your frame.

All RF bottom brackets come with an inner plastic sleeve to keep the elements out and the appropriate spacers to ensure a perfect fit.
