The ultimate tire for bikepacking and gravel adventures – and recipient of Bikepacking.com’s coveted ‘Gear of the Year’ award for the ‘Best New Component.’ Developed together with bikepacking legend Lael Wilcox, the Fleecer Ridge measures 29″ x 2.2″ (or 700C x 55 mm), making it a perfect fit for bikepacking and mountain bikes.

Named after the passes that inspire them: Fleecer Ridge is the toughest climb on the incredible Tour Divide that traverses the Rocky Mountains from Canada to the Mexican border. On a ride that long, you’ll need a tire that can handle a huge range of conditions, from snow and mud via fast gravel to pavement as you descend into towns to resupply.

The Fleecer Ridge grips like a knobby when conditions get tough. On pavement, it rolls like a slick tire thanks to its large and strategically placed knobs that don’t squirm and always put the same amount of rubber on the road. The Fleecer Ridge is the world’s first bicycle tire with noise cancellation: The staggered tread blocks create overlapping noise frequencies that partially cancel each other.

The Endurance casing is reinforced for extra sidewall protection and puncture resistance, while retaining the speed and comfort for which Rene Herse tires are famous.
