Wolf Tooth T47 Internal 24MM Bottom Bracket

The Wolf Tooth T47 Internal 24MM Bottom Bracket is made for T47 Internal bottom bracket shells and 24 mm crankset spindles. It combines best in class sealing with low friction performance and features custom chrome-steel bearings for long lasting smoothness. Wolf Tooth machines and assembles their bottom brackets at their HQ in Minnesota. This bottom bracket is compatible with T47 Internal bottom bracket shells that are between 85.5 – 92 mm wide. It requires a standard 16 notch, 52 mm bottom bracket tool to install. In addition, Wolf Tooth supplies 2x 2.5 mm shell spacers. They also supply the following spindle spacers: 2x 0.5 mm, 2x 1 mm, 2 mm, 3 mm and 5 mm.

 

Key Features

  • Lightweight Design: Carefully CNC machined aluminum parts keep weight to a minimum.
  • Robust Sealing: A combination of o-rings, seals, gutter seals and a unique end cap keep dirt and water out, keeping pedaling smooth no matter the conditions.
  • No-Creak Bushing: Custom polymer spindle bushings eliminate metal-on-metal contact, a common cause of nuisance creaks.
  • Replaceable Parts: Wolf Tooth firmly believe in the right to repair and as a result each individual part is replaceable from Wolf Tooth.

Compatibility

  • Shell: Compatible with T47 Internal threaded bottom bracket shells that are between 85.5 - 92 mm wide.
  • Crankset: Fits any crank using a 24 mm spindle. This includes all Shimano Hollowtech II cranksets.
