Two mudguards in one from Mucky Nutz - the extendable MugGuard. Actually, size is everything! And you get to decide how to use it:  Short - as an all-year-round shock guard or Long - for full-length protection, when it gets mudtastic. Each MugGuard is made in the UK using 100% recycled plastic and comes with re-useable Velcro® fasteners, so you can attach it to your pride and joy with ease. Each arm has a rubber base, for maximum grip on your seat stays and to protect your bike's precious paintwork. Arrives in a reusable, snazzy kit bag made from recycled plastic bottles. Full sus or hardtail, the MugGuard works impeccably on both. And is compatible with 26" to 29" wheel diameters and tyres up to 3" wide... possibly a tad more. Using its innovative dial feature, tune the guard's angle to achieve the desired clearance with your rear tyre.
