Replacing ClementDonnelly MSO Xplor's as my gravelmixed terrain tires on my CX bike. Running tubeless on Stan's Grails. One tire went on easily but the other took some work to seat. A compressor helped.
I've put about 200 miles on them so far, on some rough trails, and theyve performed really well. Hook up on off camber was also good for a gravel tire. Seals have held and haven't had any punctures
I was unable to mount these tires on a set of wheels on which I had run tubeless for 2 years. Given all the variables with a tubeless set-up, I can't really blame the tires - maybe something else was amiss.
Purchased the 700x38, have about 200 miles on them, Ive used these on all surface types(loose gravel, slightly muddy, pavement included) and found great traction running at just under 40 psi. Setup easy tubeless with no problems holding air since mounted.
