The first thing I noticed about these tires was how well they rode. It may be that it's my first time on 25s (as opposed to 23s), but I really appreciated the improvement in comfort. They also roll fast and seem plenty grippy. Unlike the reviewer below I had no trouble getting these on, but that is probably more wheel-dependent than anything else.
I deducted one star, however, because, despite less than 500 miles on fairly clean roads, my rear has a pretty serious cut in it. The cut did not penetrate the casing, but it went all the way through the rubber and is fairly long. Time will tell how well they hold up but I found this to be concerning.
