You need a tire that keeps your legs on their game for hours on end, provides tenacious grip in the corners, allows you to drop your buddies off the start, while remaining composed when leaned over through the first turn. Aggressive cornering knobs meets fast centerline, making for a tire that carries speed into the turns yet corners like it means it. The Riddler is just as ready for the local cross course as it is spinning down an empty gravel B-road. Rolls fast, eats corners.
