SRAM DUB PF30 bottom bracket

The SRAM DUB PF30 bottom bracket is designed for MTB frames with a 83 mm shell and PressFit 30 system, so it presses into the frame without threads. The DUB spindle is oversized and works with all bottom bracket standards for improved crank compatibility.

The PressFit cups help keep weight down, and the steel bearings offer greater durability. The manufacturer describes installation as simple, and the model complies with the ISO 4210 standard. Before ordering, check that the frame is designed for PressFit 30 with a 83 mm shell: this determines whether the part will fit.

Founded in Chicago in 1987 by Stan Day and a group of cycling enthusiasts, SRAM is still based in the US city today. It makes drivetrains and brakes for road, gravel and mountain bikes. Its story began with a single product: Grip Shift, the shifter that lets riders change gear by twisting the grip.
