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..........
