Fair - I should’ve clarified that I asked it to give me the nearest to 2.4” in width. I know some brands do 2.35” etc and not an exact 2.4”.
As for hte Dubnital - is it so much better than the old Race King that we shouldn’t really be considering other tire options? I’m cool if that’s the case. I didn’t read 3000 comments to try and ascertain that.
Still doesn’t solve for including a tire no longer available, excluding Conti’s top tire that is, and getting some of the data / details wrong.
yeah just updated my comment - appreciate your thoughts on the Dub vs. Race King
No, it isn’t better, but it is close. It’s just that it’s available, available in 2.2 and 2.4, and is Conti’s fastest tire and the Race King Protection isn’t sold anymore (unless they decide to do more production runs because everyone loves it as a gravel tire)
Other tires that should be in that list are probably Thunder Burt and Rick. Vittoria Peyote and even Barzo. If you want Maxxis - Aspen and Aspen ST.
Basically my point is AI shouldn’t be trusted in some scenarios - and in this one there were some immediate red flags getting details wrong so I’d use other sources.
(Edit - saw you updated your post with a new table and more tires - but seriously, no I wouldn’t trust gemini or chatgpt here and you’re better off not using them because it’s still getting details wrong. )
Saw you updated this - but it’s still getting details wrong.
Rick is faster than Dubnital and Ray. Peyote is about as fast as the Dubnital. Maxxis tires look generally correct. Rick XC is 100% not the 80% Trail One Tire Choice. Mezcal a Bikepacking Tire? Seriously? (Edit - and all of this is surface-dependent)
Seriously - LLM’s can be crap for this stuff, you’re better off not using them based on the results it’s giving you.
There are better sources.
If an ai summary is available to anyone who does a Google search, does adding said summary to a forum add any value even if there weren’t the questions of accuracy?
If this were true it would be so much easier to fix LLMs. LLMs use a grab bag of words based on similarity patterns found on the internet. So what comes out of them never was on the internet but superficially reads like it was.
@dhengen surprised you didn’t do the obvious thing and let the LLM of your choice summarize this thread for you. that is much more promising than asking it to get the info from random corners of the internet (which likely includes paid reviews, ads etc.)
I actually tried this. The agent can’t see the entire link, just the first 10 replies of the thread. I’d love to know how to get past this, if anyone has done this. I’ve tried this before to get Gemini to summarize entire threads when there are thousands of posts.
NotebookLM may work.
Although I’m not sure it does a great job based on just this thread, but try it out. Fast to play around with it.
That’s how the forum software works. It dynamically loads the content based on how you scroll. Not sure how to get an LLM to work through that.
We are getting off topic but I find this interesting. I prompted the agent to page through/scroll and it would do the first 80 posts and come back with a summary. Then I pushed it to keep going and eventually it’ll do some type of summary of the entire thread but I’m not sure about how much it’s reviewing. It was commenting on 2024/2025 posts. THe agent said it reviewed the major ‘epochs’ of this thread.
For me, it sounds like I can vastly improve my tire selection by goign to Dubnital or Ralph/Ray combo. I do question the grip aspect of these tires but in the right conditions they certainly seem like a winner. I can use any extra watts!
Just adding in here, this is what my LLM gave me
Based on an analysis of the “XC Race Tire Thread” (specifically the discussions from late 2024 through December 2025), the community consensus has shifted toward a new generation of tires, specifically the Schwalbe Rick XC and the Continental Dubnital.
Here is the feedback and deep dive on the best tires in each category based on the forum’s user experiences and data:
Best Rolling (Least Resistance): Schwalbe Rick XC
Consensus: This is widely considered the new speed king. Users report it is “faster on most segments” than the Hutchinson Python Race and significantly faster than the Continental Dubnital and Schwalbe Racing Ray.
Data Point: One user noted that sacrificing the “10 watts” advantage of the Rick XC to run a slower tire is a “hard pill to swallow,” cementing its status as the pure speed choice.
Best Tire Protection: Continental Dubnital (Trail Casing)
Consensus: The Dubnital (which superseded the Race King in 2025) in the Trail Casing is the top pick for durability.
Why: While the “Race” casing is lighter, the “Trail” version is praised as a “daily driver” that is tough and confidence-boosting on rocky terrain where lighter casings (like the Rick or S-Works) might fail.
Most Commonly Found / Benchmark: Maxxis Aspen
Consensus: The Aspen (often the ST or Team Spec) remains the standard benchmark everyone compares new tires against.
Why: Even with newer, faster tires like the Rick XC appearing, the Aspen is still the ubiquitous reference point for a known quantity of grip and speed.
Best Traction (Front Specific): Schwalbe Racing Ray
Consensus: For front-end grip, the Racing Ray is still the “confidence” choice.
Why: Users explicitly mention that while the Rick XC is fast, it can be “sketchy” or “scary” as a front tire in loose corners. The “Magic Combo” for many is a Racing Ray (Front) paired with a Rick XC (Rear) to balance rail-like cornering with straight-line speed.
Best All-Around (Balanced): Continental Dubnital (Grip Compound / Trail Casing)
Consensus: The Dubnital acts as the perfect “modern XC” tire.
Why: It offers a “mild upgrade” to the Racing Ray/Ralph combo—slightly faster, wider, and with better puncture protection. It bridges the gap between a fragile race-day-only tire and a heavy trail tire, making it the best single tire for variable conditions (dry to damp, hardpack to rocks).
| Category | Tire Model | Key Characteristics | Best Use Case |
|---|---|---|---|
| Speed King | Schwalbe Rick XC | Extremely low rolling resistance (-10W vs others); lightweight; fragile. | Race Day Only. Perfect for non-technical courses where raw speed is #1. |
| All-Rounder | Conti Dubnital | Balanced grip/speed; “Trail” casing is tough; “Grip” compound excels in damp/loose. | Daily Riding & Rough Courses. Set-and-forget for most XC/Downcountry riding. |
| Front Grip | Schwalbe Racing Ray | aggressive side knobs; predictable cornering; clears mud well. | Front Tire. Pair with a fast rear (Rick/Thunder Burt) for confidence. |
| Reliability | Maxxis Aspen | Predictable drift; decent volume; clears mud fast; widely available. | Dry/Loose over Hard. The standard “safe” choice for racers. |
| Distance | Vittoria Mezcal | High durability; continuous center strip rolls well; heavy duty. | Marathon/Bikepacking. When finishing is more important than sprinting. |
The “Rick” vs. “Dubnital” Debate: The thread highlights a clear trade-off. The Rick XC is the weapon of choice for pure watts (rolling speed), but it suffers from rapid wear and lack of cornering bite on the front. The Dubnital is the “super-tire” successor to the Race King—it’s not quite as fast as the Rick, but it is far more livable, durable, and versatile.
The “Mullet” Strategy: The most highly recommended setup for a rider wanting both speed and traction is mixing brands/models: Racing Ray (Front) for steering bite + Rick XC (Rear) for maximum acceleration.
AI Summary Warning: As noted in the thread (by user dhengen), be wary of automated summaries that might conflate older data. The “Rick” and “Dubnital” are the specific 2025-era tires driving the current conversation.
I still think that for 2026 a Ray/Rick combo is the ideal choice for me but am still considering going straight Dubnital for more volume.
Anyone have real world experience with these and can provide feedback?
This is what I run out at Fort Ord (Sea Otter). I’d like to run a Burt on the back, but the knobs are just short enough that I get spin out on some of the sandy climbs. Rick has just enough to dig through it.
What’s the Voting Block doing for BRR this month?
I see Continental Trinotal Race Grip 29x2.4 and Schwalbe Thunder Burt Super Race 29x2.35 as the top prospects.
They Peyote is all but a shoe in.
I’m voting for this. Would be helpful to see the estimated impact of the tread design vs other attributes of the tire.
I voted for this last month and will probably throw my vote there again.
I used the Ray/Ralph all season, the Ray was phenomenal - the Ralph on the other hand was questionable to me. I don’t mind the bike sliding a lot but if the Rick either grips more or rolls faster with he same feeling it would be a better choice in my mind.
That said, I really want them to have more volume - I think for me they are just a little narrow and I am highly considering the Dub. I am glad I do not need to make a tire choice for another 2-3 months.
I just finished testing the Scorpion XC RH and here are results across smooth pavement and three different gravel surfaces.
