A T47 threaded bottom bracket with outboard angular contact bearings, built for SRAM 22/24mm diameter crank spindles.

Highlights

  • Machined aluminium cups thread directly into a T47 bottom bracket shell
  • Angular contact bearings engage all balls across a larger surface area, cutting friction and wear
  • Outboard bearing design, typically used in shells from 68mm to 100mm wide
  • Bearings are easily serviced or replaced
  • Includes a sleeve between the cups to keep out dirt and protect internal cables and hoses

Threading and installation

Like standard BSA threaded cups, the drive side cup is left-hand thread and the non-drive side is right-hand thread. Use a quality grease on steel or aluminium shells, and an anti-seize compound on titanium shells.

Fitting

Tune's workshop can fit this bottom bracket for you — the right cup tool and torque setting matter, especially on a press-fit or T47 shell.

Compatibility & fit

Fits T47 threaded frames with shell widths typically from 68mm to 100mm, and SRAM/Truvativ GXP 22/24mm diameter crank spindles.

Wheels Manufacturing backs this bottom bracket with a 1 year warranty against manufacturing defects, plus 30-day returns. For warranty support, return the product to Tune Cycles and we'll manage the claim with Wheels Manufacturing's Australian distributor.
