microSHIFT Advent MX Rear Derailleur – 10/11-Speed, Clutched, Steel Medium

The goal of Advent MX was to create a group that would stand up to the hardest 10% of riders, and the microSHIFT engineers delivered. The MX rear derailleur features their most robust linkage ever, with a beefy horizontal parallelogram and 33% stronger clutch force. What does that mean? Go ahead and huck to flat. When paired with an MX shifter and cassette, this derailleur delivers on Microshift's signature ease of ownership and adds an entirely new level of performance.Horizontal parallelogram eliminates "ghost shifting" and reduces shift force while IGUS bushings improve lateral stiffness and longevity. Clutch is 33% stronger to ensure reduced chain slap and preventing dropped chains in even the roughest of terrains. Easy cable routing to reduce friction for a crisp, reliable shifting.
