The ACID ROOKIE 55 24” mudguard set is compatible with the CUBE Ella 240 and Numove 240 with a maximum tyre width of 1.85in. This child-specific design features the exact same clever finishing touches as the adult versions: glossy finish icon details, the ACID adapter system and the integrated lighting cable guide. The mudguards are compatible with our ACID rear light integration technology. The set also includes stays.
