SRAM OG 1090 Cassette

The main cogset of the OG 1090 cassette is machined out of a single forged form that is heat treated and then shaped in a complex series of CNC-guided operations. Weight, stiffness, and strength-wise, the OG 1090 Cassette delivers titanium’s weight with solid steel’s superior strength and stiffness.

  • Lightweight: Innovative CNC‘d chromoly steel construction.
  • Durable: 35% harder than titanium!
  • Stiff: 15% stronger than its competitor.
  • OpenGlide technology allows for smoother transition between gears.
