Your cart is empty.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 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 and is available in twelve anodised colours.

Had my pants down.The adjuster came with adapter already stuck inside and the DUB is too small to fit.Rendering it utterly useless.Looked through Youtube comments, confirmed faulty product.

Works perfectly, but it was almost impossible to put on, it's way too tight even on my worn out crankset. I'm happy that at least it's not ever coming out, though this can also be seen as a disadvantage. Miles better than the horrid SRAM plastic ring.
