That all starts with SpeedRamp, a series of 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, Advent MX delivers fast, quiet shifts so you can concentrate on enjoying the ride.SpeedRamp technology delivers faster, quieter shiftingReplaceable small cogs extend service life2 layered ED black finish provides additional corrosion resistanceCompatible with Advent MX, Advent X and Sword 10-speed systemsCompatible with standard HG cassette hub bodiesItem SpecificationsCassette Body TypeShimano HGCogs11-13-15-18-21-24-28-34-40-48ColorBlackDefined ColorBlackDrivetrain Speeds10Range11-48Weight676 microSHIFT Advent MX H-Series Cassette Cassettes EAN: 4710495438740
