Hutchinson Cobra TR RR 29 Mountain Tire. It's no wonder Hutchinson chose Cobra for this tire's moniker as its both lightning fast and strikes fear into its competitors. The Hutchinson Cobra 29 x 2.25 has a nice, wide footprint and the densely clustered knobs are optimized for stellar performance on dry, loose and rocky conditions. Additionally, the tall side knobs grip like nobody's business when you're diving into corners. A host of technology is tucked into these beauties such as the Race Riposte dual compound, Hardskin cut reducing reinforcement, plus it's good to go for tubeless set ups. And with plenty of design input from multi time Olympic and world cross country champion Julien Absalon, you know it's your ticket to the top.
