In short, it's everything you want in a high-end drivetrain. - Two alloy large cogs and a full alloy spider eliminate unwanted weight - Ramped cogs aid in shifting under load - Continuously molded construction maintains straightness and durability - Compatible with standard HG freehub bodies and 10-speed chains - Cassette Body Type: Shimano/SRAM 8, 9, 10 Speed - Cassette Cogs: 11-13-15-18-21-24-28-34-40-48
