What Our Gearhead(R) Experts Are Saying: "I've used this to run a 24mm crank in a PF30 frame and it's been solid and quiet. The external-style bearing placement gives a wide, stable stance that feels durable over time, and the serviceable bearings are a big plus. It's a dependable solution when you want compatibility without headaches."When we're piecing together a build that mixes modern frames with trusted cranksets, the Race Face EXI PressFit 30 Bottom Bracket makes everything click. It bridges the gap between PF30 frames and 24mm spindle cranks, keeping our drivetrain smooth, quiet, and ready for long days in the saddle. From trail bikes to everyday commuters, it's the kind of component we install once and forget about. By positioning the bearings externally, this bottom bracket mimics the wide stance of threaded external systems for added stiffness and durability. Precision CNC-machined aluminum cups press securely into PF30 shells, while the serviceable bearing design keeps maintenance simple. The result is a stable, efficient setup that stands up to hard riding and high mileage.
