I only have 500 miles on this set of tires. No issues great tire.I have only ridden on dry hard pavement with light moisture. Grip is great. Rolling resistance was minimal. Not any more difficulr than any other tire to put on. Matter of fact easier than some. These replaced some Schwalbe marathons. The Terra Speeds are much lighter and faster. The schwabbe served their purpose of zero flats in 2500 miles. I bought them to replace some gravel kings that I had five flats on the rear tire in 3000 miles. I would buy the Continental Terra Speeds again. Jury is still out on durability, but I think they are keepers.
I just completed my second Unbound. Previously, I rode Schwalbe G-1s and prior to that, GravelKings. Both were OK - but I've had punctures and fortunately, it self sealed and I could keep racing. My riding buddies convinced me to try Maxxis Ramblers - so, Unbound was the debut. I went with 40mm given it had rained heavily two nights prior. They performed well in fast loose terrain and were comfortable on the long race. I just came home and cleaned my bike - to my surprise, there were literally zero cuts, gashes etc. None. Tires look brand new. I have never seen this after Unbound. I am a convert.
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.
Bought on sale for a climbing century. I was concerned I would not be able to use it with my Shimano 9150 DI2 since it was not recommended. I run a sub-compact (50/34). It worked in all gears but didn't want to risk going big-big gear option. So I set my DI2 to full syncro mode and limited gear options to drop down the front to 34 when gearing down (higher up on the cassette) on the rear cassette from 27. This avoided the big-big gear selection that put a lot of stress on my rear derailer. Worked great!
