In the meantime, I have had to toss 2 Pro Ones due to side wall cuts, and a third Pro One due to the casing getting damaged - all within less than 1000km of riding. So i decided to try the regular Ones (a little more puncture protection and tan side walls): 3 flats in 500km and they feel noticeably sluggish on the ride. They sealed each time, but this experience has put me off Schwalbe for a while now..

Back to the original post - the Gravelking SKs most definitely do NOT ride too well on the road. I got a pair and sold them after 2 rides, as they were noticeably slower on tarmac. The Gravelking slicks, on the other hand, are a fantastic all-road tire. After I use up the above-mentioned POS Schwalbe Ones, i am going to use them as my training tire.
