I purchased two of these tires in a 28mm width primarily for road use. The good: Easy to install, good grip, holds the road nicely when cornering, good speed, and after about 500 miles the tire seems pretty durable (no punctures). The bad: Based on my purchase QC seems to be an issue. One of the two tires is not round. It feels like there is a hop in the tire on my rear wheel, very similar to how a plug would feel in a tubeless tire after you just fixed a puncture. It's not a horrible hop, the tire is still quite ridable. On less than perfect roads the hop is much less noticable and sometimes disappears altogether. However, I would not purchase these tires again.
I've been riding Schwalbe One HS 462 road bike tires on my road bike for about 5 years now; they have great rolling resistance and I can't remember last time I've had a flat on these tires. I have had the Continental Grand Prix 5000 tires and the Schwalbe One tires are head and shoulders above the Continental. Easy to mount and remove. And I buy nothing but Schwalbe tubes as well.
