The G3 features MRP's patented integrated skid (US Patents RE 42,436 / 8,235,849 Patents Pending), which protects critical drivetrain components like the crank and chainring from damage and glides over rocks and obstacles. The skid and lower guide are combined into one solid structure. The skid and lower guide also feature our new attachment system, the Swingset. The Swingset system features a pivot at the forward skid mount that allows the skid to swing down for super easy crank and chainring installation. - Integrated skid protects chainrings and glides over rocks and obstacles - Includes standard pulley and new G-slide slider block for quiet, dependable operation in muddy and dank conditions. - Nylon upper guide - Quietring wrap on the upper guide's tail mitigates chain-slap - 34-38t sizing - Stamped steel backplate - All install and adjustment operations possible with just a single 4mm HEX wrench. - 236g (ISCG-05)

Designed to work seamlessly with the new wave of 2×10 drivetrains, the 2x utilizes MRP's patented integrated skid chainring protection (US Patents RE 42,436 / 8,235,849 Patents Pending) and features a dual pulley tensioning system. Notable on the 2x system is the absence of a crank-mounted bash guard or guide ring, instead it relies on the front derailleur and cutting-edge lower pulley assembly for complete chain retention. The integrated skid protects the chainrings from impacts without the added weight of a full bash ring. The dual pulley tensioning system ensures that the chain is properly tensioned and in the right position, keeping it on the chainring in the roughest conditions. The dual pulleys also reduce drag and noise compared to other designs, ensuring a better riding experience. Finally, the raised top fin profile prevents the chain from dropping to the BB shell. - Removable integrated skid protects chainrings and glides over rocks and obstacles - Dual pulley design provides precise chain engagement while reducing noise and drag - Raised top fin profile prevents the chain from dropping to the BB shell - BB mounted guides are only compatible with traditional, threaded BB systems
