Description
All-new. For all mountain rides.
Aggressive riders need a drivetrain that can keep up with their riding.
Advent MX is microSHIFT's toughest and highest-performing all-new MTB 1x drivetrain series to date. It has been redesigned from the ground up to provide the shifting mechanism, durability, and feel required to handle the harsh conditions faced by modern MTBs, such as intense trail vibrations, impact from jumps, and the high torque of e-MTBs.
It delivers microSHIFT's longest-lasting toughness, faster and more precise shifting, and powerful chain retention. The system is highly reliable, allowing you to ride hard without hesitation. Advent MX is a drivetrain built for riders who want to keep riding tough.
High Shifting Performance with SpeedRamp Technology
The Advent MX G-Series cassette is a model that offers high shifting performance and durability within microSHIFT's lineup. Its unique SpeedRamp technology, which uses optimized shift ramp shapes for each of the 64 gears, enables smooth and quiet chain movement even under load, ensuring reliable and stable gear changes.
The cogs feature a wide 1.8mm profile, with the 7 cogs from 11T to 28T made entirely of chromoly steel. This significantly improves wear resistance compared to typical high-tensile steel cogs, maintaining stable performance over a long period.
