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

microSHIFT Advent MX is a purpose-built 1x11-speed HG groupset for trail and enduro riders who want fast, confident shifting and real durability without stepping into higher-cost drivetrain ecosystems. This kit pairs the MX Trail trigger shifter, MX Pro rear derailleur, and an 11-50t Advent MX G-Series cassette to deliver wide-range gearing with shifting that stays controlled when the trail gets rough.

The shifter’s redesigned internals shorten engagement from 12° to 3° for a quicker, more immediate shift feel, while the derailleur’s robust linkage and higher clutch force help keep chain control consistent through impacts and braking bumps. The cassette’s SpeedRamp shift features are tuned to move the chain quickly and quietly under load—exactly where many 1x drivetrains start to feel vague.

Key reasons riders choose this build kit

1. Fast, decisive lever feel - Engagement reduced from 12° to 3° for quicker shifts with less lever movement, especially noticeable in rapid gear changes on punchy climbs
2. Dialed cockpit fit - Removable clamp with 12mm lateral adjustment makes it easier to position the shifter where the thumb naturally lands
3. Higher chain control in rough terrain - Rear derailleur features a 33% stronger clutch to reduce chain slap and help prevent dropped chains
4. Stable shifting under load - Horizontal parallelogram derailleur design helps reduce “ghost shifting” while lowering shift force for more predictable changes
5. Durability-focused drivetrain materials - Cassette uses thicker chromoly steel cogs (11–28t) for a claimed 500% durability increase over hi-tensile steel, with an aluminum spider and 42t/50t cogs to manage weight
6. Serviceable, long-life design details - Repairable aluminum cage, sealed bearing pulley wheels, IGUS bushings, replaceable small cogs, and a nickel-plated satin finish to reduce visible wear over time

Compatibility note: This groupset uses an 11-speed cassette on a standard HG driver body and provides a wide-range 11–50t gear spread for modern 1x mountain bike setups.
