Chose these tires for several extended bikepacking trips on varied surfaces. They have met all expectations, rolling smooth and quiet on paved roads, holding traction on gravel turns and providing plenty of traction on single track. Some wear after about 1000 miles, but still lots of life.
I purchased these for a set of training tires. They are specified by Continental to weigh in at 660 grams per tire. Both of mine weigh 770 grams a piece. They set up tubeless fine, and will work, but that is quite a bit of extra weight to push around. I also bought the 'Protection' series for my next race, and those weigh in at the specified 605 grams. I'm not sure how Continental missed this weight issue. I wrote Western Bike Works and they confirmed the 770 grams for the 'Performance' series tires. Bottom line These will be fine for training, but I wouldn't use them on race day.
Replaced the Maxxis 2.2" tires that came on my Santa Cruz Chameleon with these (2.0") Contis, it transformed the bike. I mostly ride xc. These tires (with tubes) weigh less than the Maxxis tubeless setup the bike came with. They roll unbelievably better at the same inflation. (I also run these tires in a 26x2.2 on my '97 Santa Cruz Heckler.) These are ideal Summer tires for around here. Love them.
I use the Race Kings on a Trek Superfly for mostly gravel riding. The tires are great for gravel work - not sure how they would hold up on a cross country MTB trail. I'm on my second set & no problems with the tires at all - no flats & plenty of miles ridden before they show any appreciable wear.
Swapped these onto a Trek DS for snow and trail riding. Great grip aired down a few PSI. Exceeds bike manufacturer width allowed but works perfectly. Great in the snow and mud.
I ride some basic local single track trails & dirt access roads. These tires are exactly what I needed to replace the road friendly tires on my dual sport. I now have adequate traction to climb hills without spinning the tires. If I don't have adequate traction, I probably need to dismount the bike anyway.
