Look great, love the concept but they are way way way too tight. I've spent years mounting tubeless tyres on my mountain and gravel bike and this is the first tyre that's almost brought me to tears. Plan was to run them on my campag sirocco with tubes and then put them onto my new hunt carbons when they arrive. Took me a week of swearing and broken tyre assets to stretch them onto the rims, but they never quite settled. Taking them on and off always left one part of the bead not seating correctly and the net result was a pronounced wobble that was quite un-nerving. Maybe they would have been better tubeless on the hunts - but to be honest i didn't want to risk it and the thought of being stuck at the side of the road unable to get the tyre off to stick a tube in. Now replaced by goodyear f1s which went on by hand and went up on a trackpump.

Reviews
Bought a few weeks ago but it's taken this long to get the tyres onto the wheels - incredibly difficult to fit. I had to take them to a shop which also struggled for a week or so! Probably because the fit is so tight, the seal is currently weak and there is a lot of air leakage overnight. They look great on an all black Madone SLR and once they stretch to fit, I'm sure they will be fine.
