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?
