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.

• Aluminum back plate is strong and lightweight
• Works with 32-36t round rings (and 30-34t oval rings)
• 4mm of chainline adjustment (without use of spacers) so adjustments can be made quickly
• Works with most chainlines (including non-boost, Boost, and Super Boost)
• Forefront 4-way, front-accessible setup and adjustment
• Pop-Up tool-free chain access for simplified installation and drivetrain maintenance
• Upper guide features TPU co-molding to silence chain contact
• Requires ISCG-05 tabs
