Meet the tire made for no-holds-barred cross country, short track, and endurance racing, Schwalbe's Rocket Ron. This incredibly lightweight tubeless-ready tire sprints into the lead with tons of grip on its open tread pattern. And you'll stay out there with the low-rolling resistance, thanks to its light carcass, which means quickness and speed when you need it most. Please note: This is an out and out XC competition tire! Puncture protection and durability are limited!
