|The new triple compound:|
A completely new compound, the OneStar triple compound, was developed specifically for extremely low rolling resistance. "In recent years there have been major developments in compounding, without which such rubber mixes would not have been possible. The new triple compound is based on special polymers that have only recently become available," reported Markus Hachmeyer, Senior Product Manager. As a result Schwalbe has achieved a great improvement in the familiar trade-off between rolling resistance, wet adhesion and durability. The technicians have subjected innumerable rubber mixes and more than 50 prototypes to laboratory tests and practical trials.
However, the OneStar triple compound is not only faster, it also delivers the good grip we all appreciate – and it is also more cut-resistant than previous compounds. This makes the tire significantly more puncture-resistant. The tread contour with its more robust tire shoulder also helps to make the tire more reliable.
With its 205 grams the new racing tire, due to a slight increase in the amount of material used, is just a little heavier than the Ultremo ZX, which is still available. But the technical benefits more than offset this supposed disadvantage: thanks to the innovative triple compound, rolling resistance is minimized. At the same time the compound, the V-Guard and the new tread pattern make the tire extremely puncture-resistant.
Three systems: folding, tubed and tubeless tires
Schwalbe One is available as a folding tire, the traditional hand-sewn tubed tire and also as a modern tubeless version. Markus Hachmeyer sees the switch to the tubeless system as a positive move: "At present there are hardly any tubeless tires for racing bikes. However, this system offers outstanding benefits in practice. The rolling resistance is noticeably lower than with conventional folding and tubed tires because this system minimizes friction losses. At the same time tubeless systems are extremely safe and a sudden loss of air is almost impossible. There are no longer any tubes that can overheat and burst. A puncture protection fluid seals up small holes within a fraction of a second.
