Speaking for itself, Raddler is the radder version of WTBs famed Riddler tread pattern. It combines the expeditious efficiency of a short-knob centerline with the get-rad traction of chunky outer knobs. Lets call it a semi-slick, but one designed to increase confidence while youre 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.
