Mucky Nutz MugGuard

Meet the MugGuard - our super snazzy mudguard for mountain bikes, and it's made from 100% recycled plastic! 

We have developed a fully functional and sharp looking piece of kit, that will compliment your ride and keep you shredding without eating dirt, whatever the trail conditions!


Available in two sizes, the MugGuard has been engineered for maximum functionality and durability, with minimum weight. 

  • Short MugGuard is 400mm long and weighs just 75g.
  • Long MugGuard is 600mm long and weighs just 105g. The extended profile offers you maximum protection against trail slop!

Both guards are compatible with 26”, 27.5’’ & 29” wheel diameters. They are designed to fit standard and boost suspension forks, and tyres up to 3”.

The MugGuard also has the potential to work as a rear guard on some frames.


The MugGuard profile has been developed to prevent clogging when shredding the sticky stuff; with subtle features such as:

  • Forward lip to catch and minimise spray. Sharp trailing edge to cut cloggy soil away from the tyre.
  • Recessed bridge area to increase tyre clearance.
  • Wide upper arm profile to protect your seals and stanchions from mud and grit.
  • Six fastenings anchor the guard firmly to the fork, so there is no rattling and minimal movement, even in the rockiest conditions. 
  • Multiple fastening slots for increased functionality, with the potential to use the MugGuard at the rear of the bike to protect the shock, depending on frame architecture.
  • Gloss underside finish to shed muck and make for easy cleaning.
  • Made of a customised PP polymer with a UV additive, for increased life and durability in the elements.
  • Supplied with a Velcro roll for fastening, making it quick release and easily removed for transport on a bike rack / uplift if needed. You can choose Zip-Ties if you prefer.

Finished in a stealthy matt black with contrasting gloss, this is a premium looking mudguard that won't break the bank!

What does it fit?

The MugGuard is 85mm wide and will fit most standard MTB suspension forks fitted with disc brakes and a forward facing arch. Please measure the width of the fork below the arch, to ensure compatibility.

The 'legs' of the guard extend down 150mm, please ensure there is no more than 140mm distance from the underside of the arch to the top of the 'lowers' to allow room for the fasteners.

The guard can potentially be fitted to the rear of some bikes, typically used as a rear linkage / shock guard. Compatibility is not guaranteed so please ask for advice before purchasing!

There is so much variation between frame and fork manufacturers, and the geometry changes every year which makes it hard to produce a truly 'universal' product. If you are not sure about the compatibility please email us with your bike / fork model.

The MugGuard is highly unlikely to fit between older rim style brakes (V Brakes) and is unlikely to fit a rigid fork.


It's no secret that plastic is used in most of our products, and this is because it's simply the best material for the job.

As a responsible manufacturer we are committed to sustainability; to produce and sell our products with minimal waste, minimal packaging and we recycle everything we can along the way. Each product is designed to serve it's purpose over many years and is by no means a single use plastic. When a Mucky Nutz product does eventually reach the end of it's functional life, it can be fully recycled and we encourage customers to do so!

The MugGuard is proudly manufactured in the UK - using 100% recycled material.

''The Mucky Nutz MugGuard is affordable and performs impeccably. We would choose the short model for year-round riding and long for the worst of winter. If cost is a consideration, the MugGuard is really all you need, taking our BEST VALUE award'' -

PinkBike 'check-out' review:

Product Code: MN0155
Colour: Black
EAN: 5060325481279

Length: 600mm
Width: 85mm
Mass: 105g

Fitting using Velcro is very easy. You are supplied with a 900mm roll which allows for 6 fasteners.

1) Take the roll and wrap the Velcro around the fork lower, 'fluffy side facing in', and overlap this by 40-50mm. Cut two of this length from the roll. These are the bottom fasteners.

2) Repeat the process in line with where the middle slots will be positioned on the fork.

3) Wrap the remaining Velcro around the top arch in line with where they will eventually be fitted, again overlapping by 40-50mm. Cut two of these from the roll.

4) Offer the guard up to the fork and choose which top slots align with the arch, to hold the guard at the best angle to allow maximum clearance.

5) Thread the Velcro straps through the designated slots and fasten the guard to the fork. Start at the top and work your way down. Be firm with the Velcro but there is no need to over-tighten and risk damaging the guard!

It may take a little adjusting to get the guard seated firmly but after the short while it will naturally mould to the shape of the fork.
