Shimano 105 range components are always a great value. This cassette works just as smoothly as the Ultegra cassette it replaced. I really like the 11-30 gear range. It is much more comfortable when climbing the 15% grade I have to go up to get home from every ride.
Such a dependable groupset. Happy to have this cassette 11-30 available to give me a little more gearing in the mountains. That's as big as I could go with with the short cage derailleur.
