AMg

Sold out

Ride it ALL.


The AMg eliminates dropped chains and bent chainrings.

The AMg (the "All-Mountain" guide) combines a lightweight upper guide and a durable bashguard. Unlike the cheap, flexy, and rattle-prone upper guides found on competitor's products, the AMg features our premium, stiff, silent upper guide and fiber-infused bashguard.

Features

FOREFRONT

The “Forefront” feature allows for 4-way, front-accessible setup and adjustment. This broad adjustability makes installation less “trial-and-error” and more “set-and-forget.”

POP-UP

The “Pop-Up” feature allows for tool-free chain access - simplifying installation and drivetrain maintenance. The guide pops-up and snaps shut with satisfying and secure clicks.
