microSHIFT Advent MX Pro Rear Derailleur - 10/11-Speed Clutched Repairable Aluminum Medium Cage 50t Max BLK/Silver

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 Pro rear derailleur features their most robust linkage ever with a beefy horizontal parallelogram IGUS bushings at the pivots and 33% stronger clutch force. What does that mean? Go ahead and huck to flat. With other creature comforts like sealed bearing pulleys and a fully replaceable aluminum cage assembly this derailleur delivers Microshift's signature ease of ownership with an entirely new level of performance.
