Completely Redesigned. For Every Mountain Ride.
Aggressive riders need a drivetrain that can keep up with their demands.
Advent MX is microSHIFT's toughest and highest-performing single-ring MTB drivetrain series yet. It has been redesigned from the ground up to provide the shifting mechanisms, durability, and feel required to handle the harsh conditions faced by modern MTBs, such as intense trail vibrations, impacts from jumps, and the high torque of e-MTBs.
It offers microSHIFT's longest-lasting durability, faster and more precise shifting, and powerful chain retention. The result is a highly reliable system that allows you to confidently push hard, even on tough rides. Advent MX is a drivetrain created for riders who want to keep riding tough.
Smooth Shifting and Proven Durability
The Advent MX H-Series cassette is designed to deliver smooth and quiet shifting performance across a wide range of riding conditions. With its unique SpeedRamp technology, featuring 64 optimized shift ramp profiles per gear, it ensures smooth and silent chain movement even under load, providing precise and stable gear changes.
The smaller cogs feature a replaceable design, allowing you to extend the overall lifespan of the cassette by only replacing the parts that wear out.
