Advent MX H-Series 11 Speed SpeedRamp Cassette

by microSHIFT

The Advent MX cassette is the smoothest shifting, most durable cassette that we've ever made. That all starts with SpeedRamp, a series of 64 discrete shifting ramps that move the chain quickly, quietly, and precisely under load. With separate ramps for moving the chain up and down the cassette, MX delivers fast, quiet shifts so you can concentrate on enjoying the ride.
