    High quality, lighter in weight

    I rarely find myself in a cog about 45t, so why add the weight. Besides, I like the teeth count jumps to be a little closer together. It's Shimano XT, do the quality is good. Knocked it down a star on "value" mostly because it's a lot of money for a cassette. I'm use to paying a lot less for all-road cassettes (ie, 12-27).
