These are amazing tires. Fast on payment and very good in gravel. Surprised how well they handle wet conditions on the trail. Flat protection so far has been great. Tread wear is not even visible after a few months of Use.
very high quality and supple-riding tire. I wished I held off until the tubeless version was released. Mine is regular, non-tubeless clincher version. Very fast rolling on pavement and decent grip offroad. I would recommend tubeless and wider for burly singletrack or fast descending on rough surfaces. I pinch-flatted riding down the rocky road from Mt. Fromme avoiding enduro riders riding up the smoothest part of the road (and forcing me to go into the rough)
