microSHIFT Advent MX Rear Derailleur - 10/11-Speed Clutched Steel Medium Cage 50t Max BLK

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.
