Praxis BB30/PF30 73-3001R Shimano MTB Conversion PressFit Bottom Bracket – 73mm

Description

The Praxis 73-3001R bottom bracket is a solid solution for running Shimano 24mm spindle cranks in BB30 or PF30 mountain bike frames. Built with high-quality steel bearings and a carefully machined alloy shell, it addresses common creaking issues by using a press-fit design with an expanding collet system that locks the BB securely in place. It’s compatible with most MTB frames using 73mm bottom bracket shells and offers a reliable, quiet interface between Shimano cranks and press-fit frames. If you’re trying to bridge the gap between Shimano durability and modern frame standards, this bottom bracket gets the job done with minimal fuss.
