The 11-28 cassette has a good spread of gearing for any hill. Good quality cassette typical of Shimano Ultegra. I use this with my Durace drive train and it changes flawlessly.
I purchased this cassette to make my hill riding a little easier from the 11-24 durace cassette that originally came with my bike. I cant really tell the difference in shifting performance using Durace 9000, but the larger cog makes just makes climbing a tad easier on the nasty grades. This is a way cheaper option than purchasing Durace unless you are a weight weenie, and I am happy with my purchase. Thanks ProBikeKit.
