The Record UD 10 speed titanium cassettes use the race proven Ultra-Drive system. Racers and enthusiasts are always looking to reduce weight without sacrificing performance. One way we've done this is replacing our steel-and-titanium sprocket set with an all-titanium one, now manufactured in the Ultra·Drive profile. Its tooth profile contributes to Records precise and smooth gear changing. Tested under all weather and race conditions at the Tour De France, the Record Ultra Drive system worked to perfection.
Please Note: The cassette lock-ring is included ONLY on 11 tooth cassettes.

The Chorus UD 10 speed cassettes use the Ultra-Drive system and are the fruit of continuous research and development to improve products. The Ultra-Drive system makes shifting more precise and fluid, especially thanks to the careful machining and treatments that the sprocket teeth have undergone. The special sprockets pattern interfaces perfectly with the rest of the drivetrain components, especially the chain and chainrings, thus bringing performance to levels of outstanding excellence.

The OG-1090 Cassette, simplicity means elegance, efficiency, and performance. The main cog set is machined out of a single forged form that is heat treated and then shaped in a complex series of CNC-guided operations. One-piece PowerDome™ construction offers improved stiffness versus traditional designs and better power transfer to the wheel-it's also 15% stronger than its nearest competitor. The sprockets themselves (including two free cogs) utilize SRAM's proprietary OpenGlide™ design for smooth-as-silk up- and downshifts.

For use with post-1999 Record or Chorus hubs and cassettes that begin with a 12 or 13 tooth cog position. Steel. 19 g.
