Designed for: XC / TRAIL 1x10 / 1x11 / 1x12 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? CS models use a proprietary composite backplate material that delivers stiffness, durability, and performance at an amazing price-point. Features: ~ ISCG-05 range 28-34t. S3/ E-type range 28-36t. ~ 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 ~ New 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 ~ ISCG-05 and S3/E-type options ~ From 40 g (ISCG-05) Please visit our website at http://www.ecomtb.com.my OR https://shopee.com.my/eco_mtb ** There is 1-3cm errors due to manual measurement.
