Zennor Rear Gravel Guard
Built for the rough stuff, the Zennor takes its name from Cornwall’s wild granite coast and the West Kernow Way. Mounting to the seat stays and extending over the rear wheel, it delivers serious protection against mud, gravel, spray, and whatever else the trail throws at you, while keeping a low-profile look that blends seamlessly into your bike.
Made in the UK from recycled plastic, the Zennor is lightweight, tough, and trail-ready. Quick to fit, whip off, and rattle-free, its reversible rubber feet offer two mounting angles, helping it sit neatly on a wide range of gravel bikes. It’s designed for modern gravel riding on 650B or 700C wheels, with tyres up to 50mm wide.
Protecting your back, wherever the ride takes you.

FAQs
What bikes does the Zennor guard fit?
The Zennor Rear is designed for gravel and adventure bikes running 650B or 700C wheels, with tyres up to 50mm wide. It mounts directly to the seat stays, so suitable mounting space and tyre clearance are required.
How do I fit it?
It’s completely tool-free. Choose the preferred orientation for the reversible rubber feet, position the guard on the seat stays, then secure it using the reusable, non-slip fasteners. Check the position and tyre clearance before fully tightening.
Does it require mounting bosses?
No. The Zennor Rear attaches directly to the seat stays using reusable, non-slip fasteners, so no frame bosses or permanent fittings are required.
Will it rattle or rub my tyre?
When correctly fitted, the rubber feet and non-slip fasteners provide a secure, rattle-free fit, while the curved profile provides clearance for modern gravel tyres.
Can I leave it on all year?
Absolutely. It’s made to handle everything from wet winter miles to dry, dusty summer gravel, tough, stable and happy to live on your bike full-time.
What’s it made from?
Proudly made in the UK from 100% recycled plastic, lightweight, durable and built to take a beating without breaking.
Can I use it with other Mucky Nutz guards?
Absolutely. Pair it with the Zennor Front Gravel Guard for protection at both ends of your bike.
Will the Zennor Rear fit with a pannier rack?
The Zennor Rear mounts to the seat stays, so it can fit beneath many pannier racks. Its reversible rubber feet offer two fitting angles to help you position the guard. Rack and frame designs vary, so check that there’s enough space between the rack, guard and tyre on your bike.
