Speaking for itself, Raddler is the radder version of the famed Riddler tread pattern. It combines the efficiency of a short-knob centerline with the rad traction of chunkier outer knobs. You can call it a semi-slick, but one designed to increase confidence while you're pushing the limits of gravel. The 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.
