The Shimano Ultegra CS-6700 Cassette features a more rigid aluminum carrier that keeps the cogs in check when making shifts under load and each shift is lightning quick thanks to revised tooth profiles. The available ratios provide combinations that work particularly well when combined with compact gearing.

5Good cassette for hills, May 10, 2015
Posted By: Julie - verified customer
I upgraded to the Shimano Ultegra CS-6700 assette to have a wider range of gears to make it easier to climb hills and push on the descents. I bought the 11-28 which gives you 12-13-14-15-16-17-18-19-21-23. Perfect to climb but also have fun in the downhill! Very fast shipping from trivilage!
