All riders all terrain. SRAM’s most popular cassette goes 11-speed providing even better gearing options. The 11th cog and updated tooth profiles go hand-in-hand with SRAM’s cutting edge Force 22 groupset. When paired with the double crankset you get 22 useable gears right at your fingertips. Yet despite these changes the PG-1170 still maintains all the core design features of the celebrated 1070 10-speed cassette. Heat-treated steel cogs ensure extended durability and the largest four cogs are fixed to an alloy carrier for weight savings and stiffness. The PG-1170 Cassette is compatible with the Force 22 and Red 22 11-speed chains. It’s available in a variety of gear spreads. The claimed weight is 231 grams 11-25T.
