SRAM Rival DoubleTap 10-Speed Shifters
I ride up to 5000 miles per year. I switched from Shimano Ultegra to SRAM Rival. These cogs have a nice finish, and shift well spinning or under load in a full sprint with a tap of the Double Tap shifters. If you are considering Ultegra, check out Rival - reviews say it is comparable to SRAMs higher end parts for much less money. You will find yourself tapping through the shifts just for the satisfaction of hearing and feeling that positive feedback.
This appears to be compatible with Shimano 10-speed shifters. I switched wheels with my wife's Dura Ace equipped bike. She didn't notice the difference at all. This means that the cogs worked well with the DA setup cause she would have complained if there was anything wrong!
The lower cogs have one tooth removed on each cog as part of the design. SRAM says this improves shifting. Shifting is fast and the cassette runs very smooth, so maybe the marketing is true.

NEW Sram OG - 1070 10 - Speed Cassette: The "OpenGlide" shifting of the 2007 SRAM OG - 1070 will provide crisp, positive shifting under any circumstance-a mellow spin, or at max power on a steep climb . The first time you set eyes on the OG - 1070 you'll likely have the alarming realization that one tooth is missing from each of the 5 high cogs . These missing teeth have two purposes: It serves as a gateway that allows the chain to shift fluidly no matter what kind of stress you're putting the bike under . And it allows the OG - 1070 to weigh in at a scant 220g without having to resort to easily - worn titanium cogs . Rather, the OG - 1070 is made from durable heat - treated steel, giving you tons of mileage before you'll need to replace it .
