The WTB Riddler TCS Light/Fast Rolling Gravel Bike Tire is designed for riders who demand speed, traction, and durability across varied terrain. Whether you're navigating rough gravel paths on a bikepacking adventure or speeding through a cyclocross course, the Riddler delivers top-tier performance. Available in two widths, the 45mm tire is ideal for long-distance gravel rides and bikepacking, offering a more comfortable and stable ride. For those seeking speed on smoother gravel or cyclocross tracks, the 37mm tire is your go-to option, delivering lighter weight and enhanced rolling efficiency. The WTB Riddler features a semi-slick center tread that reduces rolling resistance, while the aggressive outer knobs provide traction during cornering on loose gravel. The result is a tire that maximizes speed without compromising control. The 60tpi casing provides for a supple ride with improved shock absorption, making it perfect for extended gravel rides. Equipped with SG2 puncture protection, the Riddler ensures bead-to-bead protection against slashes and punctures, allowing you to ride confidently over rough terrain. This advanced technology not only enhances durability but also improves air retention for consistent tire pressure over long rides. The tire is tubeless-ready using WTB’s Tubeless Compatible System (TCS), allowing you to run lower tire pressures for increased traction and fewer flats. Whether you're conquering gravel roads or dirt trails, the Riddler is built to handle it all. Choose between tan or black sidewalls to match your gravel bike’s style. The tanwall option adds a retro aesthetic and is slightly lighter, while the black sidewalls offer a sleek, modern look.
