The Praxis 68-3001R bottom bracket is a press-fit solution designed specifically to allow Shimano Hollowtech II road cranks to be used with BB30 and PF30 frames. Built with forged and machined aluminum cups and oversized steel bearings, it addresses the creaking and tolerance issues common with press-fit systems by using a collet-style expansion design that locks into the frame securely. The result is a smoother, quieter ride with longer bearing life all without the need for adapters or spacers. Ideal for riders looking to run Shimano road cranks on a non-threaded frame without compromising performance or reliability.
