The 1x guide is the definitive cross-country chainguide. Used on the World Cup circuit and even in the 2012 London 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" or XX1/X01 setups.
