My current bike came with a climbing cassette and i live in a place of flats. So there was no need for that cassette. So i decided to go for smaller gears for more speed. I love it, best upgrade i have done on the bike and it was pretty affordable.
great smooth shifting...I have always had the 11-28 the last year I have been using 11-32 and will never go back...I don't use the 32 that much but after a long ride and the last hill home it's great to know you have that extra gear if you are outta gas!
