Rated 4 out of 5 by from Nice for Now First you must not use this this tire as a front one .. The sizing is wrong it is not a 2.2 if you need a larger tire order the 2.4 it will be more up to 2.2. This tire was a bit hard to mount tubeless compared the Specialized Renegade control i had previously..This is mounted on a WTB frequency i19 29er. Has a rear tire traction is really good I have no slips in steep climbs and puncture protection for now is really good.. like others have mention though it seems like the tire as really a soft compound. I have not ride it that much and it melts really fast.. Please be patient for tubeless setup the tire took a couple of rides to place itself with the sealant..

Rated 1 out of 5 by from Black Chili compound is not durable I purchased the 29x2.2 X-king Protection for use as a front tire and was initially happy with the traction and low rolling resistance. However, after only about 100 miles I started to notice that the knobs were tearing and large chunks are coming off. The trails I ride in San Diego aren't particularly hard on tires, so I was shocked to see such damage so quickly. As the knobs became damaged traction has decreased. I now have about 250 miles on the tires and they look worse and worse after every ride. I will be taking this tire back in hopes that REI will take care of me. I wonder if this problem is specific to the Black Chili compound conti uses or if all of the X-kings have this problem? To give you an idea of how slowly I wore out my last front tire, I had a Specialized Ground Control 29x2.1 S-works (which is their light weight version) and it lasted me about a year of consistent riding with plenty of tread left when I cut the sidewall on a shard of glass. This included 3 months of riding in the front range in Denver, CO area which is incredibly rocky. Background: I ran the X-king at 24-25 psi tubeless with stan's sealant on stan's rims. I am 150lbs 5'10" and race competitively.

Rated 5 out of 5 by from Black Chili Sticks I didn't purchase these tires to run tubeless, so I can't offer any opinion there. My two primary reasons were to get the extra protection against the cactus thorns we have in central Texas, and because I am very happy with the Conti Sport Contact 5 tires I run on my daily driver, which also utilize the “Black Chili” compound. The tires that came on my bike were, in automotive terms, “all season” tires. They were adequate. I think of a mountain bike tire's tread design as creating “bite”, and it's tread COMPOUND as creating “stick”. The first weekend I rode this tire, I was able to make two steep climbs that I have been working on for eight months. The tire bites in soft soil, and sticks on rock, tacky soil, and even dry, powdery soil. The tire never spun. I'm sure you could make it spin if you tried hard enough, but when applying the proper technique, it works extremely well. As a point of comparison, I have also run the Schwalbe Nobby Nic, and while it has bite, it definitely lacks the stick that the Conti has. Black Chili is not just a name, it works.

Rated 4 out of 5 by from x-king lives up to hype so far Using as a front tire for mostly fire roads & single track -- hard pack dirt, sand & rocky terrain. Has performed well so far and was easy to install with Stan's no tube sealant.

Rated 1 out of 5 by from A joke The tire is definitely not tubeless ready. I have struggled for weeks to keep the thing inflated at riding pressure for more than an hour at a time. Stans sealant and laying it horizontally over and over and over does literally nothing. The foam you see on the tire is just water on the sidewall, no soap. There is so much air escaping through the porous rubber that it just sits and foams until the pressure drops to about 12psi. Avoid it like the plague.
