About Muc-Off Crank Preload Ring
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 Muc-Off's 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.

Features

About Muc-Off
Back in 1991 Rex and Marilyn Trimnell got things started with X-Lite UK. After designing and manufacturing the world’s first twin crown bicycle fork, Rex created a perfectly pink spray to clean his kit. To make a long story short, Rex’s cleaner was the best thing since sliced bread, and it wasn’t long before word got out and Muc-Off was born. Fast-forward and Muc-Off is now the go-to brand for top riders and racers from the likes of Team Sky to Atherton Racing creating cleaners, lubes, athlete performance products and more.

Michael F. ★★★★★

The CNC machining is so precise it slid right onto my crank arm without any wobble, and the 7075 aluminum feels incredibly solid compared to plastic preload rings I've used before.

Brian X. ★★★★★

Installed this to dial in the chain tension on my MTB and the 7075 aluminum construction feels like it can handle plenty of trail abuse without stripping.

Michael Q. ★★★☆☆

It looks well-machined and feels sturdy enough, but I wish the instructions were clearer on exactly how to use it for preload adjustment. It seems fine for the price, just a bit fiddly to set up.
