Fast and grabby.

The Continental X-King was developed in conjunction with the Topeak Ergon Team. The tire’s low rolling resistance makes it extremely fast, but its promounced lugs give it excellent trail-holding capabilities, as well. Low, ramped center knobs roll quickly but also provide good brake and acceleration traction. The larger, more aggressive side knobs provide cornering traction to make the X-King a fantastic all-arounder.

The X-King uses Continental’s innovative Black Chili compound. Black Chili compound reacts to surface irregularities more effectively to provide additional grip and lengthen tread life. By the numbers, Black Chili reduces rolling resistance by 20% while adding 30% more grip and improving tread life 5% over Continental’s earlier-generation tire compound.

  • High volume
  • Black Chili compound
  • Available in 2.2 or 2.4

Here's what others have to say...


Weak Sidewalls

  • Familiarity:I've used it several times

These don't perform (grip) as well as my mostly worn out Specialized Ground Controls that they replaced. Now, at 5 months, I realized why the sidewalls always look wet! It the Stan's seeping through! I lose about 4 lbs. of pressure on a 2 hour ride.... I used to hold Continental in high regard.... :(

I don't recommend and will not buy again.

Weak Sidewalls

Fast and smooth

  • Familiarity:I've put it through the wringer

I agree with Kevin's review below (posted Oct 24, 2013). I've been riding my X-King 2.2 protections this past year on both front and rear on my Niner hardtail. The front is holding up well but the rear tire looks like the pic Kevin posted, complete with a missing knob. They hold air pretty well despite visible seepage of sealant on sidewalls (which tells me it's doing its job). It's a great xc tire - fast and smooth, but a bit skittish in the loose stuff. I live in Utah and they're great on our mountain trails (Park City, Snowbasin, Corner Canyon, etc). Yesterday evening however, I barely finished the weekly Snowbasin race with about 10 lbs of pressure left in the rear tire confirming it's now time to replace. I'm considering a pair of Conti Mountain Kings.

Great tubeless option

    This is my 3rd time buying this tire. It's a great tubeless tire that performs well in all terrain! You can't go wrong with this tire!


    Oddly narrow tread

    • Familiarity:I've put it through the wringer

    I got a set of these as a gift during the winter. They set up tubeless on KOM i25s fine - I did need a compressor to seat them, but they seal well enough to inflate from zero with a floor pump.

    Initially I was a bit underwhelmed. They don't have great traction when it's muddy. I know it's not a mud tire, but other manufacturers' full knob XC tires have been more versatile for me.

    As conditions dried out, I started to like these tires better. Not that it's that challenging to make a tire that grips well on hero dirt. I do like the volume, although the 2.4s only measure 2.3" on my rims. One thing that's very odd to me, though, is that the carcass actually measures wider than the widest measurement I can get over the knobs. At 550 miles, there's quite a lot of wear to the rear sidewalls, and the cords are working their way out through the rubber. The tire has also been weeping sealant a little bit, though it's still holding pressure okay. Finally, I'm tearing the corners off some of the knobs, and undercutting them some.

    I won't be buying another set of these - I think the tread on a mountain bike tire should protect the sidewall better than that. They might sit a little better on a narrower rim, though.

    Unanswered Question

    Hi, To confirm, is this Continental's...

    Hi, To confirm, is this Continental's "Protection" version of the tire? The weight listed on your webpage is not the same as Continental's website.



    Fast Rolling, Not as Durable

    • Familiarity:I've put it through the wringer

    Disclaimer: I’ve only ran this tire as a rear. I really want to like this tire, but I’m on my second rear tire and not sure I will be moving on to a third. The pros of this tire as a rear is that it’s fast rolling, lightweight, and offers pretty predictable traction. The major downside to these tires that I found out was their durability. I was never really able to trust these tires since they would let me down in the most elementary of situations and loose air. The Protection casing, while lightweight with a high TPI, did little to protect against sidewall punctures and wear. I did not suffer any punctures into the thread area however. Tread wear was alright for a rear tire, but I think compared to a Trail King front tire you will be replacing 3 of these to every 1 of the Trail Kings up front. During aggressive descending with this tire, it is possible to shed side knobs quickly (as seen in the photo). When it comes down to it, I was probably over using this tire as I wanted a fast rolling tire without too much of a weight penalty, but the durability was not acceptable. I would save this tire as a strict XC tire, otherwise look elsewhere if durability is a concern.

    Fast Rolling, Not as Durable

    Your picture with the miss side knob looks shockingly familiar. I just found a similar issue on my front tire. Disappointed by Continental.

    How many hours/miles on the pictured tire? Not for nothing, but it looks pretty well 'loved'.


    I don't have the exact mileage, but this was maybe 2-3 months of use (maybe 300 miles).

    I have about 1,000 miles on my x-king protection 2.2 and my tires look good. The rear is worn much more then the front but I say I can probably clock another 400 miles on the tire. I ride in mix, hard pack, rooty and rock gardens (with some sharp edges) in Raleigh NC including some trails in west NC. I really like the tires and have not complains about it.
