WTB Raddler TCS Fast Tyre (Dual DNA-SG2) Black 700c 40c

WTB Raddler TCS Fast Tyre (Dual DNA/SG2)

This gravel bike tyre features WTB's Dual DNA compound which blends two high-quality rubber compounds together for superior rolling performance. Its short-knob centre tread cuts down on rolling resistance, while still providing enough bite for out-of-the-saddle traction. In addition, its centre and intermediate knobs are slightly taller than those of the Riddler thereby increasing tyre lifespan without negatively affecting rolling efficiency. Tall, toothy outer lugs ensure your favourite gravel descent doesn't unravel in the final corner, while single-ply 120tpi casing provides dependable protection at a minimal weight.

Speaking for itself, Raddler is the radder version of WTB's famed Riddler tread pattern. It combines the expeditious efficiency of a short-knob centreline with get-rad traction of chunky outer knobs. Let’s call it a semi-slick, but one designed to increase confidence while you’re pushing the limits of gravel. Raddler is an excellent choice for loose terrain where traction takes priority, but efficiency is never far behind. Lean it over, take the inside line, brake late and stay pinned with the Raddler.

SG2 Puncture Protection

These 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.

  • 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.
