Nukeproof Low Direct Mount Upper MTB Chain GuideDesigned by the Nukeproof engineers for performance, this guide ensures that you don’t drop your chain when out on the MTB trails. It features a hard-wearing alloy backplate with a composite top guide. This makes it more than capable of withstanding all the knocks and jolts as you blast across the mountain. Nukeproof has also equipped this trail-ready model with a soft rubber co-moulded into it. This also reduces wear and noise from your chain and increases its longevity. This guide fits all bikes with a SRAM S3 / Shimano E-Type front derailleur mount and comes with various washers allowing you to fine tune your chainline setup.Click here to download installation instructions.Features:Backplate Material: AlloyHardware Material: Stainless Steel Use: MTB Compatibility: 28-38T chainrings, Boost and Oval Weight: 32g (Guide, 2x bolts & 2x 3mm washers) Manufacturer Part Numbers:Copper: NPCHAGUILDMBlack: NPCHAGUILDMBLKBlue: NPCHAGUILDMBLUGrey: NPCHAGUILDMGRYPurple: NPCHAGUILDMPURRed: NPCHAGUILDMREDBuy Nukeproof Components from Chain Reaction Cycles, the World’s Largest Online Bike Store.
