Schwalbe Ultremo ZX 700x23c Road Tyre

As tyre designers the Ultremo is the pinnacle of Schwalbe ambition. They strived relentlessly to increase its speed and installed the ZX with HD Speed Guard and RaceStar Triple Compound. Both components are perfectly tuned to the requirements of an outstanding competition tire.

Features
• Significant reduction in rolling resistance
• Additional material to reinforce the tire shoulders and to ensure a considerable increase in mileage
• ZX - the best Ultremo ever!

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 specialised single compounds. They arranged these into Compound-Teams, each engineered to fulfil 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 Speed Guard:
A unique puncture protection technology only available from Schwalbe. No other bicycle tyre protection belt is as densely woven and this technology makes it possible to make a tyre 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 tyres. It provides the same level of protection but with significantly reduced rolling resistance.
