    Mucky Nutz Butt Fender Fitting Instructions

    1. Lightly squeeze the fender along the crease lines to form it into shape. Make sure it stays wider than the tyre width!

  • Mucky Nutz Butt Fender is rated 3.7 out of 5 by 3.
    Rated 2 out of 5 by from Its a flat piece of plastic? Thought this product was a bargain....... Turns out its a flat piece of flexible plastic which you fold and try and fit. Wouldn't fit very well under the seat, had to remove my saddle bag....... Final result....... Still a wet, dirty back side and back...... In my opinion its Not fit for purpose, probably keeps 10% of the dirt away?

    Rated 4 out of 5 by from Surprising yet great! I wanted something simple, cheap and useful. The Munky Nuts Butt Fender protects very well against water and mud so far. It wasn't really expensive, however, when I saw the item itself I was surprised it cost me that much. Altogether I have had no any problems so far, strongly recommend it.

    Rated 5 out of 5 by from Simple mudguard works great! I have the mucky-nutz butt fender and face fender and they work great on my bike and keep the worst of the mud off. The butt fender is great and easy enough to fit, does what it says on the tin!

Some of the parts we sell here at Halfords have been reconditioned. These will carry a Refundable Deposit or an extra surcharge amount. When you add one of these reconditioned items to your basket, we'll add this extra cost automatically.

Once you've sent us your old item we'll check it over, and then refund you the full surcharge as long as everything is ok.

Before you return your old unit please make sure it's in re-serviceable condition. So if you're returning caliper casings, you'll need to double check they aren't badly damaged or broken. If the part you've sent is found to be unserviceable, we reserve the right not to refund the surcharge.

Please note that if you're returning your old unit to our National Returns Centre then this will be at your own expense.
