Mucky Nutz Rear MugGuard – Black
The Mucky Nutz Rear MugGuard in Black is a versatile 2-in-1 mountain bike mudguard designed to keep mud, water and trail debris away from your back, legs and rear shock.
Its clever modular design allows the guard to be used in Short mode for everyday riding or converted to Long mode when maximum coverage is needed in wet and muddy conditions.
Designed for both hardtail and full-suspension mountain bikes, the Rear MugGuard fits 26", 27.5" and 29" wheels and tyres up to 3" wide.
Run it short for year-round shock protection, then add the extension when winter arrives and the trails get properly muddy.

Short Mode – Everyday Protection
In Short mode, the Rear MugGuard provides compact year-round protection for your rear shock, lower legs and the back of the bike without adding unnecessary length.
It's ideal for mixed conditions and riders who want a mudguard they can leave fitted throughout the year.
Long Mode – Maximum Coverage
When the weather turns wetter, simply fit the extension to create a full-length rear mudguard.
The Long configuration provides substantially increased coverage to help prevent mud and water being thrown up onto your back, clothing and bike.
With the extension fitted, the Rear MugGuard measures approximately 835mm long, providing serious coverage when conditions are at their worst.
Adjustable Mudguard Angle
The built-in dial system allows you to fine-tune the angle of the mudguard to suit different frame geometries and tyre clearances.
This makes it easier to position the guard correctly above the rear wheel for effective coverage without unnecessary tyre contact.
Secure Frame Mounting
Rubber-based mounting arms grip the seat stays while helping protect the frame finish.
Reusable non-slip fasteners hold the mudguard securely in place and allow quick fitting or removal without tools.
Hardtail & Full-Suspension Compatible
The Rear MugGuard has been designed to work with both hardtail and full-suspension mountain bikes, making it a versatile option for trail, enduro and electric mountain bikes.
Protect Your Rear Shock
On full-suspension bikes, the Short configuration helps shield the rear shock from mud, grit and spray thrown forward by the rear tyre.
Keeping excess dirt away from suspension components can also make post-ride cleaning quicker and easier.
Made in the UK from Recycled Plastic
Mucky Nutz manufactures the Rear MugGuard in the UK using 100% recycled plastic.
The guard is fully recyclable and supplied with reusable fasteners and a reusable kit bag made from recycled plastic bottles.
