Customer Reviews
I've put around 225 miles on these in about two weeks including the 100-mile Barry-Roubaix and, so far, my favorite gravel tires. I don't think Panaracer is exaggerating when they say these have lower rolling resistance than the GK SS. 100+ of the 225 miles I have done on these were on the road and they are smooth and quiet on all but the most glassy smooth pavement.
While most of it was probably training, I still pr'd the BRX Psycho Killer by 26 minutes on these.
Comfortable and quiet on road, dirt and gravel. Very stable in the corners. Strava says their faster than my Bontrager gr1 40, Tufo Thundero 44, Giant CrossCut Grip 45, or Gravel King sk 44. Better than expected in the mud and ice.
Just finished the East Texas Showdown and was very muddy this year. I was impressed with the traction on thick mud. The X1 stayed planted when cornering with no slippage and felt fast on pavement and hard packed gravel. Glad I ran the X1 this year.
Very nice ride. Love them.
These tires seated tubeless with a hand pump on Hunt Gravel-X Wheels. Amazing control and ride quality. I set new PRs on all my technical gravel routes previously set with the SK and SS models. Panaracer has hit a home run with this new tire addition!
