Leadville actually has corners though, I don’t think I’d want it, at least on the front

Yeah, agree on the front. Even though there isn’t much technical corning at leadville, there are enough “pucker” turns on those fire roads (and bottom segment of powerline) at high speed that a little grip up front is nice.

Bummer they won’t fit my Enve MOG. I have plenty of room with width but the tire is too tall and rubs the seat post.
Was maybe going to run these at my upcoming race but these results have me second guessing…
Maxxis Reaver HYPR-X 700 x 45 RESULTS
Possibly the most relevant round of testing I’ve done for this particular thread… finally got protocol dialed in for a 45 mm tire on rough gravel!

FYI this tire is neck-and-neck with a 28c Pirelli road tire for the final spot in BRR voting this month. It falls off the list if it doesn’t win, so if you want to see it drum-tested you should stick your vote in before the end of tomorrow.
(sort of seems irrelevant at this point since we’ve got so much more info from 2025’s gravel tire hero @jkarrasch, but still might be of interest to some?)

Hah, I actually think I still voted for the Reaver HYPR X on BRR even though I tested it on pavement also.
New 45 and 55 mm Schwalbe RX PROs came in yesterday btw

I got a race series this winter that is basically 50/50 gravel and road. Wondering if going for something big will be a negative. I was thinking 2.2 terreno xc front and 48 tufo thundero rear

I don’t think there’s a good argument for the 2.2 Terreno XC in front, it’s too slow even accounting for suspension losses. I also think the tread design is pretty bad for pavement/hardpack. The center to side-knob transition is hard and feels like a wall when getting into even mild lean angle.
Thundero 48 front/rear would seemingly be a better choice. Or Thunder Burt/Race King -level tires in the front/Thundero rear.
Are you clearance limited at the rear?

I can fit a 2.4 up front and 2.1 in the back. I am a fan of dubs they have a lot of cornering grip.
I was very content with the 50mm rx pro cornering up front, at least compared to path finder and thunder burt.

I’ve been running a 50 rx pro front and 45 in the rear for about two months or so now. I can’t imagine going back to my trusty Pathfinder Pros or honestly anything else. They roll very well and are pretty grippy when ripping down chunky or loose gravel/dirt. They are fast and corner well.

How chunky is the gravel? I would run the thundero as mentioned or even something in the 45 range that is fast rolling if its not too chunky.
Pretty mild gravel. Its during the winter so I assume mud could be a concern.

50 mm RX PRO is an easy choice here.
re the Terreno XC race… there is a new version of that out. Mega fast.

I am sometimes faster with a tire which has good grip but may be a bit slower in general. It depends on the course, cutting through corners can save more seconds than rolling faster on straight parts.
I did run Specialized Pathfinder Pro for a very long time. They are done and I‘m using older tires (Schwalbe G One Bite) for the moment. They have so much grip! By testing standards they are slower, still I‘m beating PRs here and there. (Not a scientific test though.)

I think the confidence a tire gives is something that can’t show up in testing. Like you said… it may be a “slower” tire but if you have the confidence to rip through corners you are going to be faster every time.

Has anyone tried the Schwalbe G-One R Pro 50mm, or in any other size, that can share their experience? I plan to use them for both pavement and gravel, 50/50.
I’ve had a few minor cuts in recent tires (Michelin Pro 5 35mm, Conti gpx 5000 S TR 32mm, Schwalbe G-One RS Super Race 45, in gravel bike; Aspen 2.4 in MTB bike) only happening in pavement, probably from glass shards. In the case of the Aspen it was were the casing rolls in contact with the road, between knobs. These minor cuts were sealed during the rides, but when using rollers they reopened and sprayed sealant. Putting a small plug sealed the cut, but then the tire was bumpy when using rollers. I had to patch the tires myself, as LBS did not want to patch tubeless tires intended to still be tubeless.
I’m not looking for a slick “endurance” tire that may have extra protection for cuts, just trying to avoid tires with much higher rolling resistance.
So I’m looking at the G-One R Pro 50mm (only in transparent). It looks like the knobs are tight enough so that the casing won’t roll in contact with the road, and BRR numbers look good, with even lower rolling resistance than the RS or RX siblings of same size, and may be a better fit for my use case.
I ran the G-One R in 45mm a few years ago and liked it at the time. It held up well but I wasn’t riding it in regions known to be particularly hard on tires (ie. Not flint hills or NW Arkansas). I moved on to a bike that could fit bigger tires and have mainly run Thunder Burts or Race Kings in 2.2 ever since but I did just put in an order for the G-One RS in 55mm. The RS is known to be very fast, especially when you have pavement sections mixed into your gravel ride or event. I’m very curious to see how it handles versus the Thunder Burts I’ve been using.

The bicycle station just released a video saying the 55mm g one is faster than the race king on their Enve mog. While not tested they say it’s faster than the thunder burt too.
