Having purchase the Sunrace (Driven) 10 and 11 speed cassettes I was very open to trying out the 9 speed cassette especially at such a great price point (less than twenty bucks). I had just converted one of my hybrids to a touring bike and it had a 11-32 SRAM 9 speed cassette. Having such a wide range is great when you are lugging packs up and down hills but for general riding around town for training or easy group rides wanted to get some finer control with 12-25 (don't really miss the 11 teeth - hardly use it at full cadence). The bright nickel finish is attractive and shifts nice and easy. But remember that it is a steel cassette with weight to match it is not going to replace your Ultegra or high end SRAM cassette. Now I can enjoy the similar gearing on my hybrid as my regular road bike at an easy price.;
