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.Short-knob centre tread cuts down on rolling resistance while still providing enough bite for out-of-the-saddle traction.Centre and intermediate knobs on the Raddler are slightly taller than those of the original Riddler, thereby increasing tyre lifespan without negatively affecting rolling efficiency.Tall, toothy outer lugs ensure your favourite gravel descent doesnt unravel in the final corner.Single-ply 60tpi casing provides dependable protection at a minimal weight.Available with black or tan sidewalls in 40mm and 44mm widths.All Raddler tyres are TCS tubeless compatibleNylon fibres have a flat profile, which reduces the amount of rubber needed to fill the gaps between fibres and minimises weight.
