They have strived relentlessly to increase its speed and installed the ZX with HD Speed and RaceStar Triple Compound. Both components are perfectly tuned to the requirements of an outstanding competition tire.
The result: Significant reduction in rolling resistance. Even though they used additional material to reinforce the tire shoulders and to ensure a considerable increase in mileage.
Triple Star Compound: Schwalbe have taken the development of Triple Compound a step further. In the course of innumerable series tests, prototypes, laboratory and practical tests they developed a system of highly specialized single compounds. They arranged these into Compound-Teams, each engineered to fulfill a specific job. The job description of the Ultremo ZX is “as fast as possible” so the Compound-Team is RaceStar Triple Compound.
High Density Guard: is a unique puncture protection technology only available from Schwalbe. No other bicycle tire protection belt is as densely woven and this technology makes it possible to make a tire that is both light in weight and with an extraordinary high level of puncture resistance. The latest version is HD Speed Guard that is focused on competition tires. It provides the same level of protection but with significantly reduced rolling resistance.
