    9. Unbox the ‘Muc-Off Crank Pre-Load Ring’.
    10. Slide the appropriate Muc-Off spacer ring onto the crank spindle.
    11. Check you have the correct size installed, it should be a tight fit, the spacer ring should not wobble.
    12. Remove the spacer ring and apply a small amount of thread lock to the area of the spindle where the spacer ring will be located.
    13. Slide the spacer ring back onto the spindle.
    14. Wipe away any excess thread lock - Avoid getting any onto thethreads.
    15. Rotate the spacer half a turn to ensure good thread lock coverage

  • Frequently Asked Questions

    How do I know if it fits my bike and why cannot I see a list of bikes that these fit?

    Not every bike manufacturer uses the same model of components across their entire range of bikes every year, so a list of compatible bike models would be near impossible to create. It is easy to read the bike spec or by looking at the bike to see the model of cranks are fitted and if they are compatible to fit one of these.

    Why does it not fit all cranks?

    With so many different cranks and bottom brackets available in the marketplace many different standards exist. This is designed to fit as many models as possible with as few extra attachment spacers as possible included so not to create extra waste so not to ship each not with multiple fitment attachments.

    How is this product sustainable?

    The product is designed to last a lifetime of use and canbe moved from one bike to another. No plastics are part of its construction with all packaging being cardboard.
