Just picked these up to run on a new wheelset. Super nice tires! It doesn't look like a high mileage tire, but right out of the box the tread is nice both on and off pavement. 420 grams each, and setup tubeless easily on my first try. No sidewall weeping. I may save these for special events since I like them so much. I added a bunch of new goodies to this bike all at once, so I'm still evaluating them all, but the tires get a thumbs up from me.
These tires seemed bigger than the claimed size, and I measured them at 45mm. It's because of the wide rims I'm running. Had a little leaking overnight, but I pumped them back up and shook the sealant around to seal them up. They held air during the day and I took the bike to meet up with an evening group road ride. I got some strange looks from the skinny tire crowd, but I was keeping up with the group just fine. I ran the tires at 35 psi and they are a dreamy ride on the rough chipseal pavement we have in my area. The casing is very supple. I ditched the road crew and hit the gravel for my last 45 minutes of the ride. The tread is perfect for the roads around here, and the minimal side knobbies do a decent job gripping the corners. I really like these tires, but I doubt they'll have a long tread life. They're made to race.
I'm running the 38mm Gravel Grinder TL and they're a super smooth ride. They measure close to 39.5mm on i19 rims. Easy to set up TL and a very nice ride.
