Roll like a king.

The Topeak Ergon pro team collaborated with Continental in the creation of the X-King 29in Tire, and as a result, have ridden them to success after success. Fast but grippy, the X-King rolls smoothly and quietly despite its pronounced knobs, making it the ultimate all-around tire for anything from cross-country riding and racing to Alp'cross.

Continental included its Protection technology for the non-foldable iteration of this tire. So, you can enjoy the benefit of the smooth yet grippy treads as well as enhanced puncture protection (hence the name). Conti also added an additional layer that encircles the tire to guard against punctures, and unlike puncture-resistant troughs in other brands' tires, this protection reaches wall-to-wall in order to resist damage all the way around.

Don't worry, though, because Continental has been careful to ensure that the added layer doesn't harden the feel or reduce the level of dampening comfort of the X-King. Making this possible is that Continental heavily relies on its proprietary Black Chili rubber compound in order to help the tire be all things to all conditions. And an added perk of this process is that it's succeeded in enhancing the grip of the tire, making it tougher and lighter on their treads. Essentially, the Continental engineers in Germany refined its synthetic rubbers with nano-sized particles to create a compound that reacts to surface objects more quickly, thoroughly improving grip. These particles also form a tighter bond to improve compound strength, lengthening tread life and reducing the chances that lugs will rip and tear. Compared to Continental's earlier-generation tire compound, Black Chili tires offer 20% less rolling resistance and 30% more grip, yet they also manage to improve tread life by around 5%.

The X-King 29in Tire is tubeless-ready, and Continental recommends the use of its Revo Sealant to protect against the odd mini puncture. There are a ton of advantages to having a tubeless set up including the ability to run a tire at lower pressures, and increasing the contact patch and the grip of a tire without risking bothersome snakebites. The Continental X-King II Protection 29in Tire is 2.2 inches wide and has an ideal inflation level of between 50 and 65 psi.

Please note that this tire is being offered in both a Protection and foldable version. More importantly, the foldable version of the X-King does not include the aforementioned attributes of Protection technology.

Responded on

Kernville California. Trail is rideable year round. Perfect single track for 17 miles, or double that for an out and back. Also connects to the Keyesville classic course.(race is in march) the average temperature has been 65 degrees and sunny the last few weeks.

Continental X King 29

  • Gender: Male

These are a good tred desighn tire that hook up in a wide range of terrain. They seem to be wearing well and have not given me a flat yet. The side walls have a lot of protection and that is why these tires are very stiff and need to be ran at lower pressures. The Swhalbes are definitely more compliant and handle better. But then again they have less protection.....nothing is perfect.....

Great tread design

I use this as a front tire and a mountain king 2 for the back. Continentals rubber compound wears evenly and grips well.

Unanswered Question

The option you have of the Protection...

The option you have of the Protection version of this tire is actually an image of the Mountain King II. Don't want any riders to be confused. The folding option is the actual tread pattern for this tire.
