SRAM's shifting prowess is one of its greatest selling points. The affordable PG 1050 10 Speed Cassette proves that you don't need to spend a fortune to get a stellar shifting experience. The PG 1050 uses SRAM's WiFli Wider, Faster, Lighter as the basis for its design. Using both an 11 36 and 12 36 option, you're given a full range of gears so you're never stuck doing that frantic up, down, up shifting to find something your legs like. SRAM uses PowerGlide technology to design the ramps and teeth to hold and release your chain for smooth shifting. The PG 1050 is built around an aluminum spider for the largest of the cogs to save weight. The cogs are nickel plated steel, which keeps corrosion and rust at bay for a long life. The spline configuration means that it will fit any SRAM 910 speed freehub. It works well with any 10 speed chain, although SRAM touts the best shifting from its PC 1000 series chain.
