WTB Riddler TCS Fast CX Tyre (Dual DNA-SG2) - Black - 700c}, Black
  • £16.49
  • RRP £54.99
  • Saving you £70

WTB Riddler TCS Fast CX Tyre (Dual DNA/SG2)This versatile gravel bike tyre features aggressive cornering knobs that meet at a low-profile centre tread for maximum control on the most demanding of terrain conditions. WTB has also equipped this model with its Dual DNA compound, which blends two high-quality rubber compounds together for superior rolling performance. The centreline tread features a firmer rubber compound that rolls fast and resists tread wear while the side knobs are composed of softer, slower-rebounding rubber to improve control and grip. Versatile Gravel Bike TyreBuilt for unfaltering speed through a wide range of conditions, the Riddler delivers added gusto for the rider who places equal priority on traction and efficiency. The Riddler 37 keeps your legs on their game for hours on end and provides tenacious grip in the corners. Incredibly versatile, the Riddler 45 expands the horizons of gravel riding and accommodates longer dirt tours with ease. Equally at home on your local CX course or gravel B-roads - what else do you need? SG2 Puncture ProtectionThese tyres are available with WTB's SG2 Puncture Protection, which is a lightweight nylon insert that provides bead-to-bead coverage and ensures every area of the tyre is defended against slashes and punctures. As events become progressively rougher and cyclists pedal farther, gravel gets tougher. It only makes sense for gravel tyres to become tougher as well.Features: Compound: Dual DNAPuncture Protection: SG2 Casing: Single-ply 120tpiUse: Gravel, CyclocrossLevel: TCS Light/Fast RollingETRTO: 700cx37mm: 37-622; 700cx45mm: 44-622Tubeless Ready: Yes, TCS TubelessMin/Max Pressure: 700cx37mm: 30-55 psi; 700cx45mm: 25-50 psiSingle or Pair: Single tyreWeight: 700cx37mm: 481g; 700cx45mm: 541gTechnologies: Dual DNA Compound: Two rubber compounds. The centerline tread features a firmer rubber compound that rolls fast and resists tread wear while the side knobs are composed of softer, slower-rebounding rubber to improve control and grip. All Dual DNA tyres fall within the Fast Rolling category. SG2 Puncture Protection: Nylon fibres have a flat profile, which reduces the amount of rubber needed to fill the gaps between fibres and minimises weight. SG2 was specifically designed to be a puncture protection layer, but it also improves air retention and eliminates seeping at the sidewall. Tyre Pressure Information: WTB's tyre pressure recommendations have changed over time due to further developments in technology. Riders may always reference the markings on their tyres for allowed pressures ranges, but WTB calculate pressure recommendations based on an average rider weight of 160-180 lbs and suggest increasing the minimum recommended pressure by 2-3psi for every additional 10 lbs of rider weight. Never exceed the maximum tyre pressure marked on a tyre.Manufacturer's Part Numbers: W010-0852 Black 37mm 700cW010-0853 Black 45mm 700c Buy WTB Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
