CHALLENGE Open Gravine 260 TPI Tubeless 700C x 40 Gravel Tyre
Master the most demanding routes with the CHALLENGE Open Gravine 260 TPI Tubeless 700C x 40 gravel tyre. Engineered for cyclists who refuse to let challenging weather or aggressive terrain dictate their ride, the Gravine is the ultimate choice for superior grip, control, and performance when conditions are at their worst. This tyre transforms your gravel bike into a confidence-inspiring machine, ready to conquer wet mud, loose dirt, and technical singletrack with unparalleled traction. Its design is a testament to CHALLENGE´s commitment to creating high-performance tyres for serious riders who push the limits of gravel cycling.
The Gravine stands out with its aggressive and open tread pattern, specifically developed to excel in challenging conditions. The tall, widely spaced knobs dig deep into soft surfaces for incredible braking power and cornering hold, while the unique arrangement ensures rapid mud-shedding capabilities. This means your tyre stays clean and effective, maintaining grip where other tyres would falter. At its core, the supremely supple 260 TPI (Threads Per Inch) casing allows the tyre to deform and conform perfectly to the ground, maximizing the contact patch for enhanced traction and a remarkably smooth ride quality, even over rough and uneven surfaces. This high TPI construction significantly reduces rolling resistance, allowing you to maintain speed and conserve energy.
The CHALLENGE Open Gravine 260 TPI Tubeless 700C x 40 gravel tire in Black/Tan is a high-performance option for gravel riding and racing. It features a high thread count of 260 TPI for a supple and responsive feel on rough terrain. The tubeless design allows for lower tire pressures and reduced risk of pinch flats, while the 40mm width provides ample traction and stability on loose or uneven surfaces.
The Black/Tan colorway adds a touch of style to your gravel bike setup, while the durable construction ensures long-lasting performance in demanding conditions. Whether you´re tackling rocky descents or long gravel climbs, the CHALLENGE Open Gravine tire is ready to take on the challenge with confidence and control. Upgrade your gravel riding experience with these high-quality tires from CHALLENGE.
Embracing modern technology, this tyre is fully tubeless-ready. By running a tubeless setup, you unlock the ability to use lower air pressures, which dramatically boosts comfort and grip on loose gravel while virtually eliminating the risk of pinch flats. The added puncture protection system integrated within the tyre offers peace of mind when navigating sharp rocks and trail debris. The lightweight aramid folding bead makes for easier installation and storage. Equip your bike with the CHALLENGE Open Gravine and turn every adverse condition into an opportunity to excel.
