2010 Eurobike: 2011 Schwalbe Tires

10/25/2010 : sicklines

For 2011 Schwalbe has revised their tire compounds into a variety of “Triple Star compounds”.  No longer will their downhill tires be available in the triple nano / gooey gluey compound. They have refined their tire compounds for 2011 into three different choices; VertStar, TrailStar, and PaceStar.

2011 Schwalbe Tires

Schwalbe has optimized the inner strength of its MTB tires: In 2011 all top models will have new, Triple Star compounds. It is a modular system whereby three of six new individual compounds are cleverly combined. All tires are also now “Tubeless Ready”.

“We have decisively advanced the principle of triple compounding,” explained Schwalbe technician, Markus Hachmeyer. In countless laboratory and practical tests, a total of six highly-specialist, unique compounds emerged. These were then combined as Triple Star compounds, which precisely suit the relevant application. And they are now even more practical: All new versions are now ‘Tubeless Ready’.

Previously, there had been just two compounds available in the Schwalbe MTB range: Triple Nano for MTB Race and All Mountain, plus a choice of Triple Nano, or Glooey Gluey for Downhill, Freeride and Enduro.
Lately Enduro bikes with about 160 millimeters of suspension travel have become more popular. And while a race tire primarily has to roll well and be light, a Downhill tire needs outstanding grip and puncture protection, however Enduro tires require a combination of all these properties.
In order to specifically target these different requirements, there are now three, all-new Triple Star compounds:

PaceStar – for MTB Race, All Mountain and Tour. Super-fast with a combination of low rolling resistance and durability. The tire shoulders were made appreciably softer to improve handling on rough terrain.

TrailStar – for Enduro and Freeride. Triple Nano compound was unsuitable performance-wise and the rolling resistance of Gooey Gluey was too high. TrailStar has substantially more grip, better damping and handling control. Nevertheless, the compound is not overly heavy, making it suitable for climbing too.

VertStar – for Downhill and Freeride. It is a further development of the Gooey Gluey compound, but now even softer with extremely good damping properties.

Each Triple Star compound consists of three unique compounds.  All three Triple Compounds have the same, extremely elastic base compound under the tread that makes the tires fast. All other desired properties are achieved by placing a specially selected compound in the tread center and on the tire shoulders – a different one for each intended purpose.

Yet how are compounds like this developed? “Compounding is an art in itself,” explained Markus Hachmeyer. Any rubber compound contains over 20 different variables. A bit more here, a tad less there and the rolling resistance, or hardness changes. Many factors, such as grip and rolling resistance, actually contradict each other. If one value improves, the other automatically gets worse. Furthermore there are other desirable properties such as damping, durability and cut resistance to take into consideration.

The new Schwalbe MTB tires with Triple Star compounds will be available from bicycle dealers in Autumn 2010.
