Wolf Tooth BSA DUB Bottom Bracket

The Wolf Tooth BSA DUB Bottom Bracket is made for BSA bottom bracket shells and DUB/29 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 machinea and assembles their bottom brackets at their HQ in Minnesota. This bottom bracket is compatible with both 68 mm road and 68/73 mm mountain bike frames that use a BSA English threaded bottom bracket shell. It requires a standard 12 notch, 46 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, 3 mm, 5 mm, 7.5 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 BSA (English) threaded bottom bracket shells that are between 68-73 mm wide.
  • Crankset: Fits any crank using a 29 mm spindle. This includes all SRAM DUB cranksets.
