BlackBearing B5 T47 Trek bottom bracket 86-92 mm, 24 mm axle and GXP steel

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.
