What Our Gearhead(R) Experts Are Saying: "The Slick R is next-level fast. It's got all the rolling efficiency I want for big-mile days and still feels plush over rough gravel stretches. The new casing is noticeably more supple, and I've been able to lower pressure without giving up speed or control."We reach for the Panaracer GravelKing Slick R when we're racing the clock-or just chasing that long, flowing line of backroad bliss. Built with Panaracer's lightest and most supple casing ever, the Slick R lets us corner smoother and roll faster, with a silky feel that doesn't give up durability. Its TuffTex R casing offers bead-to-bead protection while keeping the ride impressively compliant, and Panaracer's ZSG GRAVEL compound holds strong in shifting temperatures and loose conditions. Whether we're riding a fully loaded gravel rig or a stripped-down endurance machine, the Slick R mounts up easy, goes tubeless without fuss, and keeps us riding fast from first mile to finish.
