As others have said, unfortunately they don't seem to be anywhere near as durable as the gp4000s (which I have always used in the past), I've only done a couple of hundred km on them and there are already some significant cuts on the rear tyre. I could just be unlucky, but I have been riding the same roads that I always ride, and I'm always pretty careful about riding through any debris on the road so I think it's more likely the tyres. I will be changing to a set of gp4000s after these ones are dead.
Well I've done almost a full crit season on the ultremos now and I'd say that they are great tyres for racing. Unfortunately the rear was completely shredded after 2,000km so it has gone in the bin and been replaced with a GP4000s. The front is still good though and I have been really impressed with how it feels while racing, I think I will stick with the ultremo front and gp4000 rear combination for a while. I don't think I would recommend them as a durable training tyre if you are on the heavy side (I'm just on 80kg), however my partner hasn't had any trouble with hers so they may be fine if you are on the lighter side (she is about 53kg).
