SRAM Red 10-Speed Cassette
Details
All the pieces come together in one outstanding package with SRAM's Red 10-speed Cassette. Unlike traditional cassettes made by combining individual cogs, the entire Red cassette is precision machined from a single steel block, heat treated and capped with a premium nickel finish, resulting in a revolutionary cassette that's incredibly stiff, light and durable. Plus, SRAM's OpenGlide Technology removes additional material from the smaller cogs for ultra-smooth shifts every time, even under load.
