MicroShift

Advent MX 1x11-Speed XD Groupset - MX Trail Shifter, MX Pro Rear Derailleur, 11-50t Cassette

The microSHIFT Advent MX 1x11 XD groupset pairs a fast-action MX Trail trigger shifter, the durable MX Pro rear derailleur, and an 11-50t XD cassette for riders who want wide-range gearing and a drivetrain built to stay composed on rough, high-torque climbs and descents. With a shorter shifter engagement and a higher-tension clutch, Advent MX is tuned for crisp, controlled shifting when trail chatter and load would normally compromise accuracy.

Trail-focused performance details

• 3-degree shifter engagement - Shorter throw than earlier Advent designs (12° to 3°) for faster, more immediate shifts when timing matters
• 12mm lateral clamp adjustment - Removable clamp enables cleaner cockpit placement and easier ergonomics tuning; updated cable entry simplifies cable changes
• 33% stronger clutch force - Reduces chain slap and helps prevent dropped chains in rough terrain; straightforward cable routing helps keep shifting consistent
• Horizontal Parallelogram derailleur architecture - Helps reduce “ghost shifting” and shift effort; IGUS bushings add lateral stiffness and long-term precision
• Serviceable, trail-ready hardware - Repairable aluminum cage and sealed bearing pulley wheels support longevity and smoother running in wet or dusty conditions
• 11-50t XD cassette with SpeedRamp - Discrete ramping improves shift speed and smoothness under load; thicker chromoly cogs (11–28t) target wear resistance, while an aluminum spider and 42t/50t aluminum cogs trim weight; replaceable small cogs extend service life
