Our advice

Denis M.

A former racer with a keen eye for equipment

The BlackBearing T47 86-92 mm bottom bracket allows you to fit a 24 mm axle and GXP crankset onto a threaded T47 frame, such as those found on Trek bikes since 2022. Available in the B5 version, this steel bearing quality delivers high performance and excellent durability.

This bottom bracket is designed with two machined aluminium cups, ensuring optimal bearing retention even under heavy loads. This reduces creaking, optimises smoothness and efficiency, and extends the bearings’ lifespan.
