Super fast, but nevertheless with a good grip, the X-King was developed with the Topeak Ergon mountain bike professional team. Despite pronounced studs, the X-King rolls off smoothly and very quietly. No matter if you are on your own or in a team, with Race and Mountain King, the super-light X-King easily covers many uses, ranging from cross country/race to Alpcross. The X-King simply leaves its competitors behind. Its Black Chili Compound offers a solid grip and is self-cleaning. The shoulder lugs provide absolute stability in curves negotiated at high speeds. With new RS and ProTection carcass versions, puncture resistance is better than ever.
Provided for review from Germany are the Mountain King II in 2.2. and the X-King also in 2.2. Both of these are the made-in-Germany tires with Black Chilli compound and ProTection sidewalls (an added puncture protection layer makes it more resistant to cuts, purportedly adds a damping effect and also makes the tires tubeless ready – the downside is a bit of added weight) I’ve ridden them mostly on technical rooty British Columbia trails with sand, mud, steep downhills and climbs and in all manner of conditions.

Strengths: These tires off a real nice pattern and a very smooth ride. They were great through the warm and dry summer months... They seated themselves into place easily on my Flow rims with a floor pump..
Weaknesses: Well, now that things are getting a little moist (wet leaves, roots and the like), these guys just don't seem to hold as well. They are starting to slip out on me when wet. It's not that bad. Maybe they are just a really nice summer tire?
Ive put about 400 miles on these and I really do like them. They took a little extra time to fill with sealant. The sidewalls leaked pretty badly for the first week or two. I usually have to put 3-5 lbs in them every week or so. Initially it 10-12 lbs a week. There are ,y first tubeless tires and I am very impressed. I am never going back to tubes.
