To take advantage of the power and promise SRAM, and to climb any mountain you need a cassette that is up to the task.

With the new OpenGlide 1070 cassette’s semi-spidered design, SRAM has removed specific amounts of material from the smaller cogs, creating a cogset that shifts efficiently and positively in all situations.
