Have 1200 miles on these on my Specialized Tarmac in size 30, very few other choices in this size. As noted, they are very hard to mount; the master bike mechanic who put them on fought with them for way more than it took to get the Conti 5000s on, but so far they are wearing well. I have had a few small leaks in front tire, but the tubeless healed itself.
So far these are looking good, the Conti 5000's never made it past 800-900 miles on my rear (I ride on lots of chipseal roads) and they have good grip and handling.
These are not easy to get on the rims. I didn't do them myself, I had a local shop mount them for me and the mechanic (he's a master) struggled to get them on. I had the tubeless fail 3 times after sitting, but the 4th time was the charm. I really like these tires for my winter riding and switched from the usual Conti 5000's because those are not durable enough for winter riding. I have about 500 miles on them and really like them, ordering a second set now.
Finally got the tires mounted and up to pressure on my Krysium rims. We will see if I can get them stretched enough to get them on my Zipps. The jury is still out on how they perform on the road.
