Panaracer GravelKing X1 R Tubeless Tire Black/Amber, 700x40

"What Our Gearhead® Experts Are Saying: ""Gravel races demand precision, and the GravelKing X1 R delivers. The new casing keeps it light and fast while still offering that bead-to-bead protection. I’ve run the 40mm on everything from hardpack to loose-over-hard, and the grip feels dialed. These mount super easy and roll fast—basically the race-day tire I’ve been waiting for.""When it’s time to shave seconds, push harder, and hit corners with complete confidence, we turn to the Panaracer GravelKing X1 R Tire. Designed to tackle gravel with precision and speed, it’s built on Panaracer’s most race-tuned casing to date—TuffTex R—which gives it a uniquely supple feel and noticeably lower rolling resistance. We love it for hard-charging efforts where grip, control, and efficient power transfer are all in high demand. With widths from 35 to 45mm, the GravelKing X1 R balances straight-line speed and sidewall protection without adding bulk. The bead-to-bead reinforcement resists cuts and punctures on sharp gravel and loose dirt, and the ZSG Gravel compound ensures confidence-inspiring grip, even when temps drop or the route turns technical. Whether we're chasing a podium or just pushing our limits, the X1 R lets us ride with more speed and control than ever."
