Product Information
The X-GRIP Jack the Gripper Rear Tire (Hard) in 120/90-18 is built for riders who thrive on technical terrain. With a 13 mm V-shaped knob layout, this tire delivers aggressive forward traction on everything from loose gravel to embedded rock. The hard compound rubber ensures durability on dry and abrasive trails, while the proprietary No-Bounce compound helps maintain contact on uneven, low-traction surfaces like streambeds and rocky climbs.
Engineered with a reinforced sidewall, this tire enhances lateral stability in high-speed corners and sharp switchbacks. Whether you're picking your way through enduro routes or powering through hardpack, the Jack the Gripper keeps the rear end composed and responsive. Its bias-ply construction gives it the flexibility to absorb trail feedback without sacrificing structure.
