These tires are very nice!!! A bit hard to mount - but excellent other than that one issue.
I usually switch out tires to match event conditions - more road than gravel event, more dirt than road event, more gravel than dirt event, sandy, muddy, etc.
I bought these for gravel events that had unknown conditions or threw lots of stuff at you.
I rode these a few times - road, gravel, dirt, mud and grass to get a feel for them and wow are they outstanding!!! Roll good on pavement, good grip in dirt, clear mud, comfortable, durable, good in gravel. They really are a do anything tire.
I was so impressed with how they handled all conditions that I put them on my wife's gravel bike. She was strictly a road rider but wanted to join me at gravel events. I had a grippy set of tires on her bike for sure footed handling - build confidence - but they rolled slow on the road. The Cannonball on the other hand has her rolling fast on the road along with descending dirt and gravel with confidence.
I have been running tubeless for years and these tires did not want to hold air even with 1.25oz of Stans Race Sealant. I am running the tan 35mm Soft and supple and they would only hold air for a couple hours. In troubleshooting my issue I submerged the mounted tire in slightly soapy water to track down the leak and I think I have them properly seated now. However, during this process, I noticed a lot extremely tiny air leaks coming from the tan sidewalls. This was noted on both tires with less than 20mi on them.
