Challenge has already shown its dedication to providing cyclocross riders with gravel-specific options, and when the Italian company saw room for another offering, it expanded its gravel line to include the Gravel Grinder Clincher Tire. Developed with longer hard-pack and loose gravel races in mind, the tire is made with vulcanized natural rubber for more suppleness and grip than stiffer artificial rubber. Its high volume also contributes to a plush ride while increasing durability compared to Challenge's other gravel-minded options. The Gravel Grinder features a center file tread paired with raised side knobs for low rolling resistance on straights confident traction while cornering. Expecting -- and encouraging -- rough riding conditions, 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. While it's also available in a tubular version, the open tubular 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.   read more
