MRP (United States) - The 1x guide is the definitive cross-country chainguide. Used on the World Cup circuit and even in the Olympics, the 1x has a proven track record of dependability and performance.

The 1x is the perfect guide for riders and racers wanting a lightweight single-ring front drivetrain for cross-country use or riders wishing for more security out of their "narrow/wide" setups. All 1x guides feature the co-molded "TR" upper guide - lighter and quieter, what's not to love?

Features:

• Perfect for "clutched" 1x10 and 1x11 drivetrains, as well as those using chain-retaining rings (like our Wave Ring)
• Tracked and grooved upper guide / backplate interface increases stiffness and eases installation
• Co-molded "TR" upper guide with softer durometer interior for silent guidance
• Oval compatible
• All install and adjustment operations possible with just a single 4mm HEX wrench.
• Compatible with chainlines 49mm and wider
• BB, ISCG, ISCG-05, D-Mount (High DM), S3/E-Mount, Seat Tube Clamp, E-MTB: Shimano E8000, Bosch CX & Giant
• New! Trek BB Clamp - 2020 Trek Top Fuel & Supercaliber
• From 40 g (ISCG-05)
