We took the standard cassette and turned it inside out!
There are times when the simplest solution is the best one. In the case of the new OG-1090 Cassette, simplicity also means elegance, efficiency, and performance. We took up the challenge of re-engineering the cassette from a component made up of many parts down to stripped-down but exceptionally strong set of cogs that stick firmly to SRAM Red's core principles of light weight, higher efficiency, and maximized technologies.
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 never before seen in this type of application. This is truly a revolutionary design that will take you by surprise with its ingenious simplicity. The sprockets themselves (including two free cogs) have all been designed with SRAM's proprietary OpenGlide design for smooth-as-silk up and downshifts. Weight, stiffness, and strength-wise, the radical OG-1090 cassette delivers titanium's desirable weight, with solid steel's superior strength and stiffness.
