With a wider than normal 11-38t gear range, it's clear that the microSHIFT Sword cassette is made for climbing. It's also made to be as compatible and durable as possible. It fits on a standard freehub body, so there's no need to upgrade existing wheels to a new standard. And the satin nickel finish is designed to look as good after a month of riding as it did on the day you bought it.Features-All steel cogs for durability-Satin nickel finish improves cosmetic durability-Compatible with standard 10-speed chain-Compatible with standard freehub bodyItem Specifications-Color:Silver-Range:11-38-Cassette Cogs:11-13-15-17-19-21-24-28-32-38-Cassette Body Type:/ 8, 9, 10 Speed-Drivetrain Speeds:10-Weight:453-Defined Color:Silver
