79mm Road M30 BBRIGHT with R-Collet

Praxis 79mm Road M30 BBRight with R-Collet is a premium performance bottom bracket designed specifically for installing Praxis M30 spindle road cranksets into BBRight road frames. Engineered for maximum drivetrain stability, smooth bearing performance, and efficient power transfer, this bottom bracket system delivers a secure and reliable solution for modern high-performance road bikes.

Built with Praxis’ patented R-Collet expansion technology, the system creates a tight and precise frame interface that helps eliminate bearing movement, creaking, and alignment issues commonly found in traditional press-fit setups. The connected cup design improves overall bottom bracket rigidity while keeping the bearings accurately aligned under heavy pedaling loads. Outboard bearing placement further enhances crank stiffness and pedaling efficiency for responsive road performance.

The integrated compressible O-ring compensates for small frame shell tolerance variations, ensuring a consistent and secure fit during installation. Constructed from precision-machined aluminum with premium sealed cartridge bearings, this bottom bracket is designed for long-lasting durability and smooth operation in demanding riding conditions. Ideal for racing, endurance riding, and daily training, the Praxis 79mm Road M30 BBRight bottom bracket delivers dependable performance for serious road cyclists.
