SRAM PressFit 68/73mm Cup/Bearing Set

SRAM PressFit 68/73mm Cup Bearing Set is a lightweight and durable bottom bracket designed to combine the advantages of BB30 and PressFit™ technologies into a highly efficient drivetrain solution. Engineered for use with 30mm spindle cranksets, this bottom bracket delivers smooth bearing performance, reliable frame integration, and long-lasting durability for both road and mountain bike applications.

The PressFit 30™ design houses the bearings inside lightweight nylon cups that are pressed directly into the frame's bottom bracket shell. This construction simplifies installation, reduces overall weight, and improves bearing alignment for smoother crank rotation and enhanced drivetrain efficiency.

An integrated gutter seal comes pre-installed within the cups to help protect the bearings from dirt, water, and contaminants, extending service life and maintaining consistent performance in demanding riding conditions. The integrated adjuster allows for precise preload adjustment, ensuring optimal bearing performance and crankset operation.
