Mozartt HXR was created for those who likes to travel with a single chain ring crankset during their enduro or cross country journeys. You like tech talk? We use only the best quality of alloy – 7075 T651 type! We are milling the backplate of the chain guide from one block of our prestigious alloy to be sure we will produce the lightest and most durable pieces on the market. The unique design cares about your chain like a loving mother. It protects the chain ring from the impacts and rocks while keeping it in the right position. The upper guide plate uses an easy mounting feature and the soft rubber between the guide plate lets it spins flawlessly. The bash guard could be easy removed just with one tool in case on an emergency on the track.
