Jan Brakelant winner stage 2


Some may call it an unfair advantage and that is pretty much what it was with Radioshack-Leopards Jan Brakelant storming across the finishline on stage two of the Tour de France on Schwalbe's all new "ONE" tire.

We contacted the German tire manufacturer for more information on this new slice of rubber that heralds rolling resistance reductions of around 19 percent!

Forging ahead with Schwalbe One


The new racing tire is called Schwalbe One. The name alone indicates how significant this new tire is for the bicycle tire manufacturer based in the German town of Reichshof. It is produced by Schwalbe in a high-end factory set up exclusively for the manufacture of this new top-class tire. The Schwalbe One will make its debut appearance at the Tour de France, where Teams RadioShack Leopard Trek, AG2R and FDJ will be equipped with it as they line up at the start.


With its Schwalbe One the company is underlining its major objectives in cycle racing. "Schwalbe One is the fastest and at the same time the most reliable competition tire we have ever produced," emphasized Holger Jahn, Managing Director Technology at Schwalbe. From September it will be available as a folding tire, tubed tire and in a tubeless version.


The new triple compound:

Minimum rolling resistance, maximum cut resistance

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.

     Jens Voigt from Team RadioShack Leopard Trek confirms this fact: "I am very satisfied with the performance of the Schwalbe tires. I never experienced such wet adhesion, such great cornering with traditional, hand-sewn tubed tires in the past. And I'm thrilled with Schwalbe's persistence and the way the company is putting its heart and soul into constantly improving these racing tires!"


The Schwalbe One factory

Schwalbe set up a dedicated high-end factory within its production plant in Indonesia, specifically for the manufacture of these tires. "It is a completely new unit where only Schwalbe One tires are being produced, with fixed vulcanization and production units that are used exclusively for this tire. This is where the most skilled workers in the entire Schwalbe plant can be found," stressed Markus Hachmeyer. This helps to ensure a consistently high quality and reliability.


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.

     Schwalbe One will be available from specialist bike shops from September 2013. Prices:  49.90 euros for the folding tire, 64.90 euros for the tubeless version and 84.90 euros for the hand-sewn tubed tire.
