Built for the long haul, the Gravel Grinder Pro Handmade Tubeless Tubular tire features a file tread center pattern providing efficiency and grip across varying surfaces. With a raised aggressive shoulder tread, the Gravel Grinder tire offers great cornering confidence even on unpredictable road surfaces.
Challenge's tubeless tubulars utilize a unique design featuring a latex liner fused to the casing, replacing the traditional inner tube, allowing for the use of a plug to finish a ride or race in case of a puncture too large for sealant to fix.
