You can fit precision-made, durable bearing and sealing technology for GXP to your bike with the Press-fit bottom bracket cups by ACROS. Angular contact ball bearings made from stainless steel are ideally adapted to high axial and radial forces and distribute the pressure evenly, particularly when riding out of the saddle, for more rigidity and rotation efficiency.

Under high stress, too, the quality bearing with special grease ensures lasting smooth running. ACROS uses the moulded R3 sealing with plate-reinforced sealing lip. This reliable sealing construction offers high protection from dirt and washing out with low friction values.

R1 bottom bracket A-BB Press-Fit bottom bracket cups GXP for MTB / Road

This did not last any longer than a standard SRAM bottom bracket. The bearings got washed out with wet weather. The special bearings , seals and grease did not perform. Stick with cheaper SRAM.
We would like to thank you for taking the time to evaluate the bottom bracket and regret that it does not meet your expectations.
