I picked up a set a of
Schwalbe Ultremo tires and now have about 400 miles on 'em. These are sold only in sets and I found 'em
here for $87 (versus the $120 MSRP). The tires were for my primary road bike and replaced the heavier (by 100g/ea) and more robust Continental Grand Prix.
I ride on local roads that are generally in various states of disrepair and there is a great deal of glass on the roads as well. As a fairly aggressive clyde, I'm pretty hard on rubber.
The ride is very nice @ 120psi (middle of suggested range) and quite supple. Very much like Veloflex Pave tires I tired last year. They won't make up for bad bridge seams, but take the bite out of the surface irregularities pretty well.
Flat protection seems to be working, but given the number of cuts I'm seeing, this doesn't strike me as the primary strength of the tire. None yet (knock on wood), but they do seem to pick up bits and hold them until skimmed by hand.
Cornering is damn good. I actually shagged the edges a bit yesterday on a criterium. You can lean these things with considerable confidence. Oddly, there is no discernible edge to the tread. Strange, but good now that I think about it.
Durability is suspect. Really, I'm not sure these will go 1000 miles. They show no signs of squaring off, but are scrubbed pretty hard. Time will tell, but having to buy them in sets doesn't help the matter.
Overall, I'd buy these again. As a high-performance clincher, they are now my favorite.
