OpenGlide, the key to smooth performance in competition and on the open road. To take full advantage of the power and promise of the SRAM Rival gruppo, you need a cassette and chain that are up to the task. With the new SRAM Red Cassette’s semi-spidered design, we’ve removed specific sections of material from the small cogs, creating a cogset that shifts efficiently and positively in all situations. OpenGlide technology allows for the smoother transition between gears when up and downshifting. Semi-spidered design is light, strong and efficient.
