Challenge Dune Pro Tubular Cyclocross Tire

The Dune excels in sand, hardpack, and even ice. The center of the tire features a small file or "pyramid" tread with bigger edge knobs for cornering. Offered here in the classic tubular "look" with black tread and tan sidewalls.

Each Dune features a seamless latex inner tube with removable valve core for easy use with Challenge Extenders when used on deep tubular rims.

TECH NOTE: this is a tubular bicycle tire with a captive (stitched-in) latex inner tube (also called a "sew-up".) It must be glued or taped onto a tubular rim for safe use. It will not work on a traditional clincher wheel/rim. Proper setup is essential for your safety - if you are not qualified to install tubular tires, please seek expert guidance first.
