TUFO Flexus Primus 33 SG Tubular 700C x 33 Rigid Gravel Tyre
Dominate every cyclocross course and conquer challenging gravel routes with the TUFO Flexus Primus 33 SG Tubular tyre. Engineered for all-around performance, this tyre is a top-tier choice for competitive racers and serious enthusiasts who demand uncompromising grip, stability, and control in a wide variety of conditions. Whether you´re navigating muddy corners, accelerating on wet grass, or powering across hard-packed dirt, the Flexus Primus 33 SG delivers the confidence you need to push your limits.
Designed as a versatile weapon for mixed-terrain disciplines, this 700C x 33 tyre excels where others falter. Its sophisticated design focuses on providing maximum performance when it matters most. The foundation of its exceptional capability lies in its advanced tread. The unique new self-cleaning tread pattern ensures excellent traction by actively shedding mud and debris, maintaining a clean contact patch with the ground for consistent grip lap after lap. This means more power gets transferred directly to the trail, giving you a distinct advantage over the competition.
Cornering precision is paramount in cyclocross and aggressive gravel cycling. The Flexus Primus 33 SG addresses this with special side knobs that provide for stable cornering. These aggressively shaped knobs dig into soft ground and provide a solid, predictable edge when leaning the bike into tight turns, allowing you to maintain speed and choose more aggressive lines with complete confidence.
Ride quality and comfort are not sacrificed for speed. Thanks to its specially formulated soft tread compound, the tyre enhances shock absorption. This advanced construction smooths out rough terrain, reducing rider fatigue over long races or epic gravel adventures. By absorbing vibrations, the tyre also maintains better contact with the ground, further improving traction and control. The tubular construction allows for running lower pressures without the risk of pinch flats, maximizing the tyre´s footprint for unparalleled grip and a supple ride feel that is simply unmatched by standard clincher setups.
The TUFO Flexus Primus 33 SG is built to withstand the rigors of racing, featuring a durable casing with a dual TPI count that balances sidewall robustness with under-tread suppleness. It is the ultimate tubular tyre for riders seeking a reliable, high-performance solution for all-around cyclocross and demanding gravel cycling.
