Toddwrote a review of Rotor UNO 11-Speed Cassette on June 14, 2018
Familiarity: I've put it through the wringer
Been running this for the past 6 months on weight weenie build. Cassette is a little louder than say a Dura-Ace or Red22, but overall performance is on par, and shifting is not compromised with the weight reduction. Weighed 2 cassettes now and both came in right at 133.9g with included lockring. Solid cassette option for anyone looking for a lighter option, and works with both 10 and 11 speed freehub bodies.
