Challenge Gravel Grinder Tubeless Ready Tire

Challenge has jumped into the tubeless revolution in a big way, and their Gravel Grinder line now comes in this TLR (tubeless-ready) option, ready for use with today's modern tubeless wheelsets. Perfect for exploring gravel or dirt roads with your gravel or cyclocross bike.

Fast-rolling center strip, big edge knobs for grip on gravel
The Gravel Grinder features a fast-rolling center section with a diamond pattern, and bigger edge knobs for cornering grip.

TLR tubeless-ready option for modern rims
Check your frame/fork for tire clearance because these are big! Choose the 700x38 for all-day adventures, or the 700x42 if you want even more volume for tough conditions.
