The Challenge Gravel Grinder is designed for gravel-specific 'cross racing or riding. Featuring a center file tread paired with raised side knobs for low rolling resistance on straights confident traction while cornering. With unpredictable terrain in mind, Challenge also reinforces the nylon casing on the Gravel Grinder with its Double Puncture Protection System (PPS2) to get you through your rides and races without losing time changing flats. This clincher model was designed to be the best option for cyclists racing on aggressive terrain. The Gravel Grinder fits on most rims measuring between 17 and 23mm wide (though its healthy girth recommends it most on the wide end of that spectrum), and weighs in at a claimed 375g.

The Challenge Gravel Grinder Pro Tire measures 36mm wide. Claimed weight: 375g.

Perfect for gravel!!

I used these tires for the Dirty South Roubaix gravel race, and they performed flawlessly!! Strong, durable, and took an absolute beating on different terrains and worked perfect! Would highly recommend for choppy and gnarly gravel events.

Great riding tire but very difficult install

These tires roll fast and grip well in the dirt. My only gripe is that they were very difficult to get on the rim. Having had may years of experience as a bicycle mechanic, if you asked me to count the top 5 hardest tires to mount ever, but the time I got to these I'd be holding up my middle finger. I fear if I got a flat while riding, I would not be able to change it in the field.
