The proven Challenge road products, (Strada, Paris-Roubaix and Strada Bianca), all with herringbone treads are available in HTLR at €69.90 / $79.90, with some of the lowest weights in the market.

The popular Gravel treads (Strada Bianca, Almanzo and Gravel Grinder) are also released in HTLR with the similar pricing and with very competitive weights for gravel tires.

Also launching at Eurobike are the first Gravel Handmade Tubeless Tubulars (HTLTU). All Challenge Gravel treads now offer this unique HTLTU system that maintains all the performance benefits of the best handmade tubulars. A latex liner is fused to the casing, replacing the traditional inner tube, allowing for the use of a plug to finish a ride or race in case of a puncture too large for the sealant to fix.

Challenge owner and President Alex Brauns today confirms, “It has been our goal to be at the forefront of truly handmade tubeless ready products for a long time but the industry standards had not been defined. With new ETRTO and soon ISO standards in place, we are proud to lead the way with our unique, artisan HTLR products that we believe deliver the best possible ride in terms of performance, handling and comfort.”

The new products will be displayed in A3-202 at Eurobike in Germany 4th-7thof September and be available to the market approximately November 2019.
