SRAM
Red 1090 10sp Cassette

• SRAM 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 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.
• The sprockets themselves (including two loose 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.
• Weight - 155g inc lockring for 11-23
