Musguard is a fender manufacturerer and they came up with an awesome solution for portable fenders: Minimalistic, easy-to-use, durable, perfectly fitting most bikes (especially fixed) and last not least: rollable.
When not in use it packs very small. It can be rolled on your frame or simply stored in your bag, pocket or hung on your key chain.
It is die cut from a strong, resilient and recyclable polypropylene (PP) plastic sheet using a unique folding system for stability and firm fit.
The application is simple and fast, no tools needed. It fits neatly, very close to the wheel catching the spray right at the source.
Originally designed for use on fixed gear / single speed bikes, Musgard fits most frames with paired seat stays and a brake bridge. Works best on bikes without a rear brake.
