You’ll have to give us an update on how they ride and their durability. What ID does your wheel have? I’m guessing 25mm.
Will do. Yep 25 mm Reserve rim
Finally, the new tires have been announced! Let’s hope the Dubnital (terrible name, by the way) meets expectations and turns out to be a wider version of the Race King.
According to Continental’s website, the Dubnital in the Race Casing with the Rapid compound is being marketed as their new “race tire.” However, there’s no mention of the available width anywhere on their site. Does anyone have more details on this?
Moving away from the Race King branding is so silly. Easily one of the most well know XC tires beside the Mezcal’s world wide 
Interesting to see a surface structure again on the side walls. We will see if these are designed on purpose and have similar aero effect as it is assumed with the Race Kings.
Am I reading the Continental press release correctly when I conclude this means there’s finally the 2.4” Race King ProTection that the MTB world has wanted for years but that we’re not getting the narrower 2.0” version we’d all hoped for in the gravel world?
That’s how I see it.
From their own press release:
“The new tires replace the iconic Race King, Cross King, and Mountain King ProTection models”
Time to get rid of those icons!!
Am I reading this right - that is a 29x2.0 tire that weighs 350g and is faster than the 700cx45mm Terra Speed? Wow.
That’s it, yeah. Also like 10 year old backstock of some kind.
Even width to 50 Tracer but a bit taller profile. Cat 2 and 3 gravel next assuming I don’t destroy the tires.
Just wrapped up off road Chung Method testing on the infamous Maxxlite 29…. Definitely NOT in the BRR database.
Finished up testing on the new Pathfinder TLR Fast Gravel 700 x 45 for anyone interested!
Do you have plans to test the Schwalbe tyre line up? they are very popular in european races - not sure about US. R Pro, RX Pro, RS Pro would be great. I feel they may be as quick as the caracel, but available in 50.
funny how 700 x 50 seems some kind of tipping point in tyre designation. Maxxis calls their maxxlite 29x2.0" instead of 700x50. MTB tires are traditionally in inches wheras roadtires are traditionally in cm. Gravel converges between the two. When can the world agree that the metric system is superiour to the imperial system 
thanks @jkarrasch for all your free data and testing!
Hear hear!
On that note - do you have a donations link for us to support this work? I feel like you might have mentioned something further up the thread but that was before I really started to understand what exactly it is you’re doing and, if that’s the case, I’m probably not alone.
I know you’re taking primarily donations and loans of tires, but if we can all fling you some pennies to help cover your (presumably high) sealant usage, other consumables, and a bit of consideration for your time, then I’m sure there are a growing number of us who would love to help as much as we can. (Particularly those of us outside the US who aren’t really in a position to send you any tires.)

My requests list would also include one or more of those Schwalbe Pro 50s fairly near the top.
Tufo Gravel Thundero 48 is the other one I’m really curious about - prior to the 2025 releases this seemed like the go-to for most likeminded riders who are still limited by frame clearance. That includes me for another season so I’d love to know how it stacks up against the Tracer 50 and the G-One R(S)(X) Pro 50 in particular. I’d loan you my set but I’m in Scotland so that’s probably cost prohibitive!
Also want to see that new Caracal Race 45 lined up as soon as it becomes available this Summer!
Yep. Setup a Patreon HERE
I’m definitely planning on doing Thundero 48 and one of the Schwalbe 50s.
Terreno XC race 2.1 next.
What I REALLY need is someone to send in a set of the new 2.2 Contis… I might have something really spicy to compare them to.
Oh it’s a tipping point for sure. You can even see it in bead to bead tire width measurements. On that note I am likely saving cat 3 tests for tires 29 x 2.00 and larger. Too much puncture risk smaller than that.
You can kinda see manufacturer resistance to 29 x 2.10 but if a good one came out it would be a killer.
There are two kinds of countries in the world…those that use the metric system and those that put a man on the moon.
