This review is the for 40c tire. Inflated on Enve G23 wheels and after riding, they settled in at 40mm @ 34psi. Weight was 465 & 473. I am still experimenting but using the SRAM PSI app as a guide, running them at 34 f, 36r. Coming off of Specialized S-Works Pathfinders (42) provided an excellent comparison of 2 of the fastest tires. The G-One RS are clearly faster tires as evidenced on ride times and power meter readings. The G-One's are supremely Supple, despite the narrower width, on firm smooth dirt/gravel (Steamboat) they feel very similar to a challenge tire and significantly quieter than the PF's on paved surfaces. They have fantastic grip on steeper climbs and braking was better than the PF's. The side lugs work well for added grip and stability. They corner very well, and you can feel the side lugs engage in loose stone/sand when angling the bike. The PF's (inflate to 45 on G23's) do have a slight edge for compliance when the roads get rougher but the G-One RS's more than make up for any lost time once things become smoother and didn't feel out of their element, just not as compliant. Overall, the G-One RS's are faster and even more supple and smooth on hardpacked Dirt/gravel surfaces (grade 1-2) but aren't as compliant on Grade 3 surfaces as the PF's, but still do a good job on those conditions. The rebound (hysteresis) of this tire is exceptional and undoubtedly part of what makes this tire so fast and supple. Riding on moderate washboard, it felt stable and composed, equal to the PF. I give the G-One higher overall scores. If you ride on smoother, more consistent surfaces and ride on sections of paved with some grade 3 surfaces, these tires are exceptional.
I bought some of these second hand, low miles, in size 35mm. They were destined for an "all road bike" and/or an older cross frame I was building up with limited clearance. Otherwise I'm on the "bigger is better" train for gravel bike tires. But seeing as the 700x45s are unobtanium, I was pretty happy to have had a good reason to run 35s. Let me tell you, these tires are fast af. They have a super sticky and soft compound that feels premium, I'm not sure how long they'll hold up. I haven't run them on any really gnarly stuff yet, just a couple gravel rides, some play around on buff xc trails and a bit of loose dirt road descending. I will say they are not the most confidence inspiring in terms of grip. But they are 35s, and I'm not expecting much. I'd say they perform about as well as a 35 slick would + a little extra. Run them a tad lower pressure and I think they will perform admirably but not astonishingly well. There are other tire choices if that's your bag. They were designed for the SBT course and I think they'd excel there and in similar conditions. I myself raced SBT on Challenge Strada 36mms and thought they were just right.
I got these tires for racing at SBT GRVL, as I wanted something fast, but prefer to have some grip rather than a total slick. I could not have chosen a better tire. I rode the 100 mile Blue course, composed of mostly well groomed, wide gravel roads, but the course does have a few trickier sections. There was primitive, non-technical single and double track, some silty, rutted Jeep road, and a single descent with ruts, bumps and some bigger loose rocks. The tires inflated out to 40 mm on my Roval 25 mm (inner) width rims, and I ran them at 35 psi R and 33 PSI F. They ended up being fast everywhere, including on the road sections which were mostly flat and downhill with lots of fast drafting. The ride was supple and very comfortable. And, they had enough grip for me to pretty much be passing folks everytime we came to any descent with cornering, as I was confident in both the grip, and the feedback the tires gave as to when they might start to slip a bit. These are highly recommended for fast gravel riding and racing in mostly dry conditions.
I rode DK200 on Donnelly MSO because of their ruggedness and left them on for a year after. I wanted to find something more supple and faster and the reviews of these were great. They lived up to the hype. A fast tire but not only that they grip exceptionally well. I was taking turns faster and I'm not a daredevil. Also they pumped up to the exact size: 40mm. My other 40's pumped to a shade under 42. So these are true to size listed.
Just finished MidSouth on these and they are as advertised. People were flatting left and right. A few times I hit some chunky gravel at speed and thought for sure I was about to flat but they just kept rolling. Fast and durable.
I replaced my Rene Herse Bon Jon Pass with the Schwable G-One RS and it was major step change in performance. The G-One RS are quiet and quick on the tarmac and feel super confident cornering on the dirt.
Bought the 40s. They didn't feel as snappy and responsive as other tires that I've ridden. Definitely not as supple either. Only put 100 miles on them before switching back to my Tufo gravel thundero.
The 'best' gravel tire for you depends in large part on where you live and how you like to ride. I've tested dozens of tires and have talked to product managers and winning pro racers and test-lab engineers about various models. I do most of my riding in the often-dry state of Colorado and the American west, and the G-One RS is my favorite, hands down.
