Challenge Gravel Grinder Race Clincher Tire


The Gravel Grinder Race from Challenge tires offers a superb way to get off-road. They feature a fast-rolling center section with some edge knobs to handle the cornering duties if things get loose.  

Their supple 120 TPI casing helps conform to rough roads and bumps, enhancing comfort and grip. This is a tire you can ride all day on a variety of surfaces; pavement to get to the trail and enough grip to keep exploring once the road ends - you'll be limited only by your sense of adventure. 

  • 700x33
  • 60-90 PSI / 4-6 BAR
  • PPS puncture protection system
  • claimed 365 grams
  • Aramid folding bead, nylon casing

This is not a tubeless tire. Designed for use on clincher rims with an inner tube inside.
