Maxxis Ardent Race MTB Tire - EXO - TR - 3C The successful Ardent trail tire gets its race legs. The Ardent Race is the fast XC and Trail riders dream, taking the proven aggressive tread pattern, and taking it low profile to give it more zip. Straight-line speed and cornering confidence make for a winning combo. The TR version comes with the tubeless ready bead allowing you to mount the tire with a tube or tubeless. Maxxis 3C Triple Compound mountain technology uses a harder, longer lasting base layer and two progressively softer top layers in order to optimize traction and stability.
