The Muc-Off Crank Preload Ring is a super durable precision CNC machined 7075 piece of hardware. It allows you to precisely adjust the ‘preload’ tension on the bottom bracket bearings. What does this do? It helps to remove the side-to-side play and slack in thru-spindle bottom brackets to help maximize the life of your bottom bracket bearing as well as giving you a creak-free ride. It fits onto the left crank arm of any mountain gravel or road bikes that have SRAM RaceFace or Easton 30mm spindle cranks or SRAM DUB 28.99mm spindles installed.
