The Schwalbe G-One R Performance Tubeless Tire is built for the rider chasing speed on light gravel, forest paths, and pavement without giving up puncture protection. Its Race carcass keeps the ride supple and fast, and a RaceGuard insert under the tread guards against the sharp debris that would end a ride on a less protected tire. What Our Gearhead(R) Experts Are Saying: "The angled side knobs surprised me on a wet gravel descent where I expected to lose the rear end in a corner and didn't. That grip held even as the trail turned greasy."
