The SRAM DUB PF30 bottom bracket is designed for MTB frames with an 83 mm shell and a PressFit 30 system, so it presses into the frame without threading. The oversized DUB spindle works with all bottom bracket standards for improved compatibility with cranksets.
The PressFit cups help keep weight down, while the steel bearings provide greater durability. The manufacturer describes installation as simple, and the model complies with ISO 4210. Before ordering, check that your frame is designed for PressFit 30 with an 83 mm shell: this determines whether the part will fit.
