Minoura Derailleur Guard DG-1 for 9mm Q/R

The Minoura DG-1 Derailleur Guard is a lightweight product that takes a preventative measure to bicycle service by protecting the derailleur and derailleur hanger simply by attaching to the rear hub quick release skewer. This is especially useful for kids or anyone who takes a “rough and tough” approach to having fun on their bike, and can save a lot of money on future repairs.
