The X-King is Continentals variant of an all-purpose mountain bicycle tire. The X-King matches the difference between the Continental Race King and Continental Mountain King. I have been using the X-King RaceSport on the front wheel of my MTB for nearly two decades and have been pleased with the grip and opinions it gives. I picked the X-King since I presumed rolling resistance could be quite near this Race King RaceSport.
The Continental X-King Is Quite like this Schwalbe Rocket Ron (inspection). Both wheels have marginally wider spaced knobs when compared to some Continental Race King or Schwalbe Racing Ralph. After analyzing the Rocket Ron, it is clear wider spaced knobs does not necessarily mean rolling resistance will be greater. Additionally, after analyzing a great deal of tires, casing structure as well as the rubber compound appear to be the dominant factors which affect rolling resistance.
Among those things that is obvious once you compare the Continental Rate King II (inspection), Race King(inspection) and X-King side by side is that the Speed King and Race King use the identical casing structure. The Speed King and Race King step very near the promoted size. The X-King on the flip side, while using the exact same 2.2 score, is considerably smaller and obviously has a different structure. Additionally, this is evident when glancing the wheels: The Speed King and Race King collapse under their own weight while the X-King can support itself and resembles a wire bead tire.
All rolling resistance evaluations are conducted on our rolling resistance test system. Read our The Evaluation page for a detailed explanation about how we examine tires.
Do not forget to have a look at the review pages to make it simpler to compare all of tires which were examined.

The X-King employed for this evaluation has a burden of 564 g, which can be marginally more than the advertised weight of 555 g. I already mentioned that the X-King is little to get a 2.2 sized scooter. The measured diameter of the casing is 53 mm, the maximum width of these knobs is 52 mm, the height of the scooter is 51 mm.
Knob height in the middle of this tread is 2.5 mm (like Race King and Rocket Ron). The knobs in the edge of the scooter have a height of 4 mm, which can be greater compared to Race King (2.5 mm), but slightly lower than the Rocket Ron (4.4 mm)
Following a remark on the Vittoria AKA inspection, I analyzed the X-King before and after eliminating the mould hairs. The X-King is among the hairiest tires I have had in my palms. Cutting the mould hairs led in ~1 watt less rolling resistance. All information in this review will be using the mould hairs eliminated.

Rolling resistance is greater than I anticipated – most Continental bicycle tires have an extremely low rolling resistance. I anticipated the X-King to be near the Race King and Rocket Ron, but in fact, rolling resistance is greater than both those tires. In an air pressure of 55 psi, the X-King includes a 2.1 frequency higher rolling resistance when compared to the Race King and 0.4 watts higher when compared to the Rocket Ron. In 25 psi, this drawback develops to 3.5 and 3.2 g respectively.
Although the X-King, Race King, and Rate King have been defined as with a 3/180 shell, it appears the more compact X-King carcass does not possess the exact same low rolling resistance as the shell utilized on the Race King and Rate King. After assessing and celebrating the two tires, I guess that the X-King and maybe the Mountain King are constructed to some more heavy-duty spec.
The outcomes of the puncture tests again demonstrate that the X-King casing is significantly more powerful compared to the Race King casing. The X-King scores 10 points at the tread puncture resistance evaluation and 6 points at the sidewall puncture test. This is a little greater compared to Race King and Rate King, which both scored 7 points at the tread evaluation and 4 points at the sidewall test.
I anticipated the Race King (inspection) and also X-King to be quite close from the rolling resistance and puncture resistance evaluations as both possess a 3/180 casing along with the exact same compound. Additionally, I established this to the Schwalbe Racing Ralph (inspection) and Schwalbe Rocket Ron (inspection) evaluations -both wheels have a very similar rolling resistance. In fact, there are far more differences between the X-King and Race King than simply the tread pattern. The X-King includes a 2-3 watts higher rolling resistance, but in precisely the exact same time scores much better from the puncture tests.
2 decades back, I made the tough decision between the Continental X-King and Rocket Ron as a front tire. I picked for the X-King since I already knew the Race King needed an extremely low rolling resistance and presumed the X-King to be quite near this Race King. I have been quite satisfied with the X-King, did not have any issues with it and use is quite low, but I’ll try out a Rocket Ron as it wears out. I will give it a score of 5 / 5 since I really do like it and it’s served me two years without any problems.
