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
