SRAM PressFit 68/73mm Cup/Ceramic Bearing Set

SRAM PressFit 68/73mm Cup Ceramic Bearing Set is a premium bottom bracket solution designed to deliver maximum drivetrain efficiency, smooth bearing performance, and lightweight durability for high-performance road and mountain bikes. Featuring precision 42x30x7mm ceramic cartridge bearings housed within lightweight composite PressFit cups, this bottom bracket is engineered for BB30 cranksets used in PF30 and compatible frame standards.

The ceramic bearing construction reduces friction and improves rotational efficiency, helping riders achieve smoother pedaling performance and enhanced power transfer. The lightweight composite cup and sleeve assembly simplifies installation while maintaining a secure fit within the frame.

Designed to support a narrow Q-factor and increased ankle clearance, this bottom bracket improves rider comfort and pedaling ergonomics. An integrated gutter seal protects bearings from dirt, water, and contaminants, extending service life and maintaining long-term performance. The integrated preload adjuster allows precise setup for optimal bearing operation and crank performance.
