MUC-OFF - CRANK PRELOAD RINGS

Description

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 maximise the life of your bottom bracket bearing, as well as giving you a creak-free ride. It also comes in our classic anodised colours for added bling!

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.
