SRAM MY12 Cassette OG-1090 10-Speed

Light, stiff and smooth. It all comes together in one outstanding package with SRAM's OG-1090 10-Speed Cassette. Unlike traditional cassettes made by combining individual cogs, the entire OG-1090 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 cogs for ultra-smooth shifts every time, even under load.
