Carefully adjust the bottom bracket bearing preload to remove any lateral play and slack from the bottom bracket. This helps maximise your bottom bracket bearing life and gives you a creak-free ride. It fits the left crank arm of any mountain bike, gravel or road bike with SRAM, RaceFace or Easton 30mm spindle cranks, or SRAM DUB 28.99mm spindles. Precision CNC machined, 7075 aluminium body and threaded adapter ring for a perfect fit.
