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 strippeddown 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 desireable weight, with solid steel's superior strength and stiffness. |
