Actually, size is everything! And you decide how to use it:

* Short - as year-round protection
* Long - for full-length protection when it gets muddy

Each MugGuard is made in the UK from 100% recycled plastic and features reusable VELCRO® straps, making it easy to attach to your bike.

In short, it is excellent as year-round protection, keeping your rear wheel and calves safe from dirt kicked up by the rear wheel.

And when the weather turns, you can simply attach the extension for full-length protection.

Whether you have a full suspension or a hardtail, the MugGuard works perfectly on both. It is compatible with wheel diameters from 26" to 29" and tires up to 3" wide... maybe even a little more.
