MUC-OFF CRANK PRELOAD RING

Muc-Off Crank Preload Ring — precision CNC machined from 7075 aluminium for durability and reliability. Adjust bottom bracket bearing preload to eliminate side-to-side play and slack in thru-spindle systems. Removes creaks, extends bearing life, and delivers a smoother, quieter ride. Available in anodised colours for a polished finish. Compatible with SRAM, RaceFace, and Easton 30mm spindle cranks, plus SRAM DUB 28.99mm spindles on mountain, gravel, and road bikes. Simply fits onto the left crank arm — no special tools required for adjustment.
