The AMg eliminates dropped chains and bent chainrings. 

The AMg combines a lightweight upper guide and a durable integrated bashguard. Unlike the cheap, flexy, and rattle-prone upper guides found on competitor’s products, the AMg features our premium, stiff, and silent co-molded “TR” upper guide. Coupled with a super-tough, fiber-infused bashguard, the AMg will give you the confidence to ride new lines.
