Challenge Almanzo Tires. The Challenge Almanzo was designed with the classic gravel grinder in mind. It crosses the line between road and Cyclocross tires to provide the performance and comfort needed for long gravel/dirt road rides.
Tread is hand-glued onto an inflated tire body; this process yields a neutral state for the tread when the tire is in use and eliminate tread deformities at full-inflation
File tread pattern provides excellent grip with a wider, more forgiving profile for those bumpy roads
