CHALLENGE Open Flandrien 300 TPI Tubeless 700x33 Gravel TyreConquer the most demanding routes with the CHALLENGE Open Flandrien 300 TPI Tubeless tyre, a masterclass in performance engineering designed for the modern gravel cycling and all-road adventurer. Inspired by the infamous cobbled classics of Belgium, the Flandrien is built to provide unwavering speed, superior comfort, and tenacious grip when the pavement ends and the real challenge begins. This is the ultimate choice for riders who demand versatility without compromising on performance, whether on rough asphalt, hard-packed dirt, or light gravel paths.The Flandrien´s intelligent tread design is central to its versatile character. It features a fast-rolling, file-like center pattern that minimizes resistance on smooth surfaces, allowing you to maintain impressive speed and efficiency on the road. As you lean into corners or encounter looser terrain, the more aggressive and pronounced shoulder knobs engage, digging in to provide exceptional stability and confident handling. This dual-nature design ensures you are perfectly equipped for the unpredictable surfaces that define gravel cycling.Experience a ride quality like no other, thanks to the exceptionally high thread-count 300 TPI casing. This incredibly supple construction allows the tyre to deform and conform to the micro-imperfections of the road surface. The result is a significant reduction in road buzz and vibration, leading to enhanced rider comfort and reduced fatigue on long journeys. This suppleness also maximizes the contact patch with the ground, dramatically improving traction and providing a sublime, connected-to-the-road feel.As a modern, high-performance tyre, the Flandrien is engineered with a cutting-edge Tubeless Ready (TLR) system. By forgoing an inner tube and using a sealant, you can safely run lower tyre pressures. This unlocks a new level of performance, offering a larger contact patch for superior grip on loose climbs and descents, increased comfort over rough sections, and the peace of mind that comes with self-sealing protection against most common punctures. The folding Aramid bead ensures a secure fit to the rim while keeping the overall weight low. The 700x33 size strikes the perfect balance between agile handling, low rolling resistance, and sufficient volume for comfort and capability on mixed terrain.Attributes:* Wheel Size: 28´´- 700* Tyre Width: 33* Tyre Type: Folding* Discipline: Gravel cycling* Technology: TubelessTechnical Specifications:* Size: 700x33c* ETRTO: 33-622* Casing: SuperPoly 300 TPI* Bead Type: Aramid, Folding* Tyre System: Tubeless Ready (TLR)* Recommended Pressure: 2.3 - 4.1 BAR (33 - 60 PSI)
