Superior Protection and Lasting Smoothness
The longevity and performance of this bottom bracket are centered around its high-quality Bearings. It utilizes precisely sealed cartridge bearings to deliver a consistently fluid and resistance-free pedal stroke from the very first ride. To protect these vital components from the harsh realities of mountain biking, SRAM integrates its innovative Gutter Seal Technology™. This advanced sealing system creates a formidable barrier, drastically improving protection against the relentless intrusion of water, mud, dirt, and grit. This meticulous engineering extends the life of the bearings significantly, ensuring you enjoy peak performance, all-weather reliability, and more time on the bike instead of in the workshop.
