mrp-amg-chain-retention-system-28-32t-icsg-white, MRP AMG Chain Retention Systems. the All-mountain Guide features MRP's patented integrated skid protection and shares the freshly updated upper guide from the G3, but lacks a lower retention mechanism. The All-mountain Guide is a great choice for 5-6" travel bikes when used with the latest tensioned rear derailleurs or on its own for shorter-travel trail bikes or hardtails that require bash protection. The contact-free, "upper-only" chain retention means the All-mountain Guide will be virtually silent and completely drag-free when pedaling. The patented integrated skid will protect your crank and chainring and prevent the chain from ever contacting and potentially damaging your expensive frame.Quietring wrap on the upper guide's tail mitigates chain-slap for quiet, muted chain retention performance in even the roughest terrainIntegrated skid protects chainrings and glides over rocks and obstaclesNylon upper guide features tracked and grooved backplate interface and pivoting faceplate that allows for stable and straightforward installationNo specialty tools neededAll install and adjustment operations possible with just a single 4mm hex wrenchCompatible with 8-11 speed drivetrains
