Don't let a dropped chain on the last lap lose the race for you!
The 1x is the perfect guide for riders and racers wanting a lightweight single-ring front drivetrain for cyclocross and gravel 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?
Perfect for "clutched" 1x10 and 1x11 drivetrains, as well as those using chain-retaining rings.
Tracked and grooved upper guide / backplate interface increases stiffness and eases installation.
New co-molded "TR" upper guide with softer durometer interior for silent guidance.
