Speaking for itself Raddler is the radder version of WTB’s famed Riddler tread pattern. It combines the expeditious efficiency of a short-knob centerline with the 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.
