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.


  • Fast-rolling center features tightly spaced knobs that cut down on rolling resistance while still digging into any terrain for dependable traction
  • Toothy side knobs help you hold your line through loose gravel and trail conditions
  • Single-Ply 60 TPI casing provides dependable protection at minimal weight
  • TCS tubeless compatible

I bought these tires to run tubeless on a dedicated set of gravel wheels. The first thing I noticed was how light they are for a tour with this amount or tread. After i put them on the run and inflated them i noticed there was air bubbling the tire sealant out of the sidewalls. I'm sure it will seal up eventually but buyers beware, you MUST USE SEALANT or TUBES and expect them to go flat. I'm taking them on the first two gravel ride today, crossing my fingers they perform well and finally seal up but I'm bringing extra CO2 cartridges just incase.
