Microshift Advent MX Pro Rear Derailleur (Black) (10/11-Speed) (Medium Cage) (w/Clutch) (Aluminum Ca

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. 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 Repairable aluminum medium cage allows riders replace damaged cages to extend the rear derailleur life Pulley wheels feature sealed bearings that offer ultra-smooth operation and prevent the entry of contaminants to increase longevity Easy cable routing to reduce friction for a crisp, reliable shifting Compatible with Advent MX 11-speed and 10-speed systems Backwards compatible with Sword and Advent X systems Specifications Largest Cog50Rear Der/Shifter CompatibilitymicroSHIFT ADVENT XRear Derailleur Mount Type10x1 StandardDrivetrain Speeds10Drivetrain Speeds11Chain Wrap Capacity (teeth)39Cage LengthMediumColorBlack/SilverWeight358keyword searchSwordkeyword searchAdvent X
