At the Eurobike trade show to be held in Germany from August 31 to September 3, 2011, Michelin will present two new mountain bike tires: the Michelin Wild Grip’R2 and the Michelin Wild Race’R Ultimate. Scheduled for market launch in early 2012 – and in autumn 2011 for certain sizes of the Wild Grip’R2 – the new tires are already in use by Team GT Skoda Chamonix, which began fitting its bikes with the tire at the beginning of the 2011 World Cup season.
The Michelin Wild Grip’R2
The Michelin Wild Grip’R 2 is the new multipurpose tire that delivers superior performance on both dry and muddy terrain. A large number of innovations set it apart from its predecessor, including its new design, tread, tubeless and tubeless-ready casings, rubber compounds and size line-up, which includes a 29-inch model.
On the tire crown, tread blocks have been optimally arranged to provide the best balance between grip, rider output and self-cleaning capability without sacrificing performance in one area for another.
On the shoulder, the height and angle of the tread blocks have been enhanced to ensure consistent, efficient cornering.
Three sizes will be available in the autumn – the 26×2.10 Wild Grip’R Advanced, 26×2.25 Wild Grip’R Advanced, and 26×2.10 Wild Grip’R – with the other sizes scheduled for market launch in early 2012.
For the Advanced portion of the range, a new generation of rubber compounds has been developed, called Gum-X Series.
Gum-X Seriesis the most recent MICHELIN mountain bike compound. It integrates all the latest technologies to satisfy the expectations of the most demanding mountain bikers. Gum-X Series offers the best balance between grip, rolling resistance and longevity. The Gum-X Series compounds are available in a variety of Shore hardness levels.
The tire has already scored a number of wins in 4X World Cup competition with bikers Anneke Beerten and Céline Gros.
The Michelin Wild Race’R Ultimate
The Michelin Wild Race’R Ultimate is the new tire for cross-country racing. During the development phase, engineers focused on delivering superior dry-terrain performance. The tire’s strengths include its low weight, speed, grip and puncture-resistance. In size 26×2.10, the tubeless-ready version of the tire weighs only 415 grams. This exceptionally low weight is obtained without sacrificing the tire’s ability to withstand punctures. Top-three World Cup finishes by bikers Fabien Canal and Fanny Bourdon attest to the tire’s outstanding performance levels.
The tire will be available in early 2012.
The tread design of the Wild Race’R Ultimate is based on that of the Wild Race’R presented at Eurobike 2010. While the crown is the same as that used on the Wild Race’R, the shoulders have been reworked to deliver exceptional rider output while maintaining lateral traction that is progressively responsive and sufficient for pure cross-country use.
The tire features a round profile that provides comfort and consistent grip.
The tire will be available in three sizes – including a 29-inch version – and made with Gum-X Series compounds.
