The new ACID Mudguard Set MUD ROOKIE redefines the design of kids' mudguards with sportier aesthetics that slot seamlessly into our mudguard range. The mudguards attach to CUBE bikes using a seat stay adapter with an adjustable angle. For all other bikes, a classic universal bracket is included. Side cut-outs mean they're also compatible with V-brakes. This set fits 18in and 20in bikes up to a maximum tyre width of 2.25in.
