Schwalbe

Ultremo ZX 700x23 Evo High-Density Speed Guard

Great tire for speed and grip on dry surfaces, I don't have enough experience on wet to comment. they do get a lot of nick's and cut easily, got a flat on one on 2nd ride, called Schwalbe and they sent me a replacement after sending photo's. They claimed it was caused by damage but sent me a replacement anyway. so I have to give A for customer service. they responded to my warranty request email within 5 minutes on a Sunday night at 9pm. Very impressed! Super light, grippy and fast with a 145psi. Compared to Pro3's these are faster but not as durable.

These tires have a lot of grip and very low rolling resistance. I just did a spirited ride yesterday morning after it had rained all night. Lots of wet and sandy corners, and I felt very confident. On a previous ride we encountered sections with tiny broken glass in the bike lanes, several other had flats during the ride. I found a few nicks on the rear tire afterwards, but nothing deep. I switched to these tires after reading the great reviews and comparos against the popular Conti GP 4000s. I have been riding the 4000s since it first came out, and the previous generations before that. The very first thing I noticed when I rode these was their stiffness. The contis were fast, but had a had a velvety feel, and at 115psi felt very smooth on the rough pavements. By contrast with the same PSI the Evo transfers all the bumps and lets the bike's dampening features filter out the road feel. I can't say if these are faster than the GP 4000s but they roll and grip well. However, if you think more PSI has any benefit, then these tires will feel very stiff.
