Derived from the super fast Michelin Jet S MTB tire, the Cyclocross Jet cyclocross tire benefits from the same chevron fin center tread design, ample cornering knobs and advanced green Silicium compound and has already helped win the womens world championship. For courses with a mix of terrain, some racers use the Jet on the back with the CycloCross Mud2 on the front. Aggressive, race tested tread pattern, bites hard in the mud for maximum grip when you need it most. Kevlar bead. Black tread-wall. Size-700 x 30mm
