The website says "the benchmark against which all gravel tires are measured" and I believe it! A great tire. Somehow it's is sticky as all get out (unless you want to ride muddy slop), but robust too. I really don't know how they did it at any price point, much less the great price you can find these online, but I don't have to worry about it. I'll just keep buying them and riding with confidence.
Upgraded to the Panaracer Gravel King SK from Maxxim that came on my Lauf. Feel heavier but the rolling on pavement and grip on gravel is superb. More confident to do Unbound Gravel with these that are nearly bombproof. My Lauf can use up to 54c clearance i believe. Love the new tires. Thanks!
These are great tires and my only complaint is that they have stretched 3mm over 60 miles. Other than that they are great. If you have less than 45mm clearance on your bike I suggest getting the 40mm due to stretch.
