The Schwalbe Ultremo ZX is a pure-bread racing tire with the security of a lightweight/ high-density puncture guard. Schwalbe combines two unique technologies: RaceStar Triple Compound and HD Speed Guard. The RaceStar arranges three single compounds on the tread, each a different durometer and designed to fulfill a specific job while reducing the rolling resistance by 15 percent. The addition of the HD speed Guard belting under the tread offers great puncture protection and higher mileage with minimal weight. The ZX is the best Ultremo ever. 195 g. Black, red, red stripes, blue strips, silver stripes, white stripes, or graphite. 700 x 23.

Been using in NYC for 18 months. Great ride quality. Only one flat (heavy glass). Loved Vredenstein Tri-Comps but these are superior. Plush ride like a tubular. Light weight. The tread gets a lot of cuts but not through the casing. Worth the $$$
