The MRP AMg SL chainguide eliminates dropped chains and bent chainrings. It combines a lightweight upper guide and a durable bashguard, mated to an aluminum backplate. Unlike the cheap, flexy, and rattle-prone upper guides found on other products, the AMg features our premium, stiff, silent upper guide and a tough fiber-infused bashguard.
