The Wheels Mfg PF30 to SRAM Bottom Bracket with ABEC-3 Bearings lets you use your favorite 24/22mm crankset with that new PF30 frame. Made with Enduro ABEC-3 bearings, high carbon chromium alloy races, and machined aluminum cups, this bottom bracket will keep the cranks turning smoothly mile after mile. A dual silicone seal blocks out particles for a longer overall life, and at a claimed 153g, it won't stack up needless weight. The Wheels Mfg PF30 to SRAM Bottom Bracket with ABEC-3 Bearings is compatible with 24/22mm spindle cranksets such as SRAM and Truvativ without any adapters needed. It features an easy-to-install threaded design that addresses the creaking and bearing alignment issues we've all come to associate with PressFit bottom brackets.
