To take full advantage of the power and promise of the SRAM Force groupset, you need a cassette and chain that are up to the task. With the new SRAM PG1070 10-speed Cassette's semi-spidered design, you'll get the high level of shifting performance that SRAM is known for, but with an improved and much quieter cassette/chain combination.
