E Thirteen LG1+ Chain GuideThe ultimate in lightweight race day chain retention – from the World Cup circuit to your home track! The all new, completely re-designed LG1+ guide offers the same world class chain retention in a lighter, stiffer, and far more adjustable design. The ISCG05 mount holes offer more adjustment than any of the competition, and the upper/lower sliders have a further range so riders can achieve ideal fit and positioning. A modular assembly allows riders to choose from one of three sizes of bash guards (included), and to remove the lower slider completely if deemed unnecessary for less intense terrain. All polycarbonate parts are now solvent resistant, so they wont get brittle or crack after exposure to lubes and cleaners. The Gen 2 Stealth Idler is softer and quieter. The upper slider has a co-molded soft rubber interior to cut down on noise, and it opens quickly and easily without tools Features: Primary Uses: Winning World Cup downhill and 4X races, bike park Back Plate Material: EXA+ Alumiinum Drivetrain Protection: DMB (direct mount bashguard, three sizes included) Sliders: Adjustable w/ ring size indicator, removable lower Slider Hardware: EXA+ captive alloy Lower Armature: Adjustable indexed slider Chainring Range: 28-38t Roller: Gen 2 stealth idler Weight: 136g (30T), 159g (34T), 167g (38T)Buy E Thirteen Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
