Schwalbe G-One RS Gravel Tire Test – Gravel Bike Tires – Tires
The Schwalbe G-One RS is the latest addition to the German manufacturer’s line of gravel bike tires. This new tire is specifically designed for gravel racing and features a lightweight carcass and directional tread pattern, delivering fast rolling performance and good grip.
Schwalbe claims the G-One RS is its fastest gravel tread yet, with 20% less rolling resistance than its G-One R tyre.
My two months of testing were on the rocky, very muddy roads of this year’s Unbound Gravel and also included gravel riding in Colorado and Utah.
Details and specifications of the Schwalbe G-One RS
- Claimed weight: 505 grams
- True weight: 518g and 522g for our 700c x 45mm test tires
- Claimed width: 45mm
- Actual Width: 45mm on a 25mm internal rim
- Tubeless Ready
Designed for speed
In keeping with the race-focused theme, the G-One RS is built on Schwalbe’s Super Race casing, first used on the Pro One tubeless road tyre. It features two overlapping 67 TPI plies laid under the tread and a V-Guard belt to prevent punctures.
The sidewalls are constructed with three ply to balance abrasion resistance with compliance. The tire is then coated in Addix Race dual compound rubber with a tougher rubber in the center and a softer, grippier rubber around the edges.
The G-One RS features directional tread – a design rarely seen in gravel tires. This two-in-one approach delivers many of the benefits of specific front and rear tires in a single tread pattern.
In the case of the G-One RS, the front tire is designed to be mounted with the edge knobs angled forward to provide cornering grip, while the rear tire should be mounted in the opposite direction to allow the Scaled center and paddle-shaped edge. knobs to provide climbing traction.
Performance of the Schwalbe G-One RS
My time testing the G-One RS began with an afternoon tire swap before Unbound Gravel. I bet Schwalbe’s last gravel tread would be just enough to see me through whatever Mother Nature threw at us on race day.
The G-One RS is available in 35, 40 and 45mm sizes to suit different courses. I chose to test the wider option, which is true to size when mounted on 25mm internal width rims. I settled on 26 psi front and 28 psi rear for my 150lb/68kg rider weight.
Given that my first ride on my pair of test tires was one of the most grueling gravel race courses, I learned a lot in a short time.
My first impression of the G-One RS was how quiet it rolled over pavement: the sound of silence was an early indicator of how fast this tire was rolling over gravel.
Durability was paramount in my mind while testing in the Flint Hills of Kansas. The belted construction prevented any sharp flints from piercing the tires, and the three-ply sidewalls didn’t make wear worse either.
Post-Unbound, on my less demanding gravel roads in Colorado and Utah (which are often smoother with more dirt and sand than rock), the soft, high-volume case did a great job of dampening braking bumps.
Meanwhile, the edge knobs work as advertised, providing reliable grip on hard and loose on hard turns.
The G-One RS is not a tire that I expected to do well in wet and muddy conditions and, as expected, it performed poorly in thick mud. However, this can be said for all gravel slicks and semi-slicks of similar design.
The other weakness of the G-One RS is loose, sandy climbs. Small edge buttons and minimal center scaling can’t do much. In these conditions, the tread is not deep enough to provide the bite necessary for good traction.
With these limitations in mind, the G-One RS is still a tire I would recommend to anyone looking for a race-ready gravel tread.
How does the Schwalbe G-One RS compare to the competition?
The G-One RS sits in a tight middle ground between slick-center tires like the Specialized S-Works Pathfinder and Vittoria Terreno Zero, and more aggressive gravel racing favorites like the Panaracer GravelKing SK, the Maxxis Rambler and Schwalbe’s own G. -An R.
The closest rival to the G-One RS is Vittoria’s Terreno Dry. Both tires feature unidirectional fish-scale tread patterns across their centerlines with small but effective edge knobs.
The G-One RS is a 700c affair only available in 35, 40 and 45mm widths. Vittoria, on the other hand, offers the Terreno Dry in 31, 33, 35 and 38mm sizes in 700c, as well as a 650b x 47mm option.
There are also 29×2.1-inch and 29×2.25-inch versions of the Terreno Dry that will fit a handful of gravel bikes, like the new Lauf Seigla, but are primarily intended for cross-country mountain bikes.
Schwalbe has fewer widths for its G-One RS, but its options are more in tune with today’s gravel market, especially the high-volume 45mm version I tested.
Also, having raced both the G-One RS and the Terreno Dry at Unbound, I think the G-One RS is the better of the two tires, based on the softness of the carcass and the higher volume options. available.
Another tire that could be compared to the G-One RS is Specialized’s fast-rolling S-Works Pathfinder.
The Pathfinder is slightly narrower at 44.5mm when mounted on a 25mm wide rim, but it’s lighter on the scales with a measured weight of 441g compared to our Schwalbe test tire the heaviest at 522g.
In terms of ride quality, my back-to-back qualitative tests suggest the G-One RS is at least on par with Specialized’s premier gravel tire, with more predictable cornering grip and increased traction on loose climbs.
In my experience, this makes the G-One RS a better set-and-forget gravel race tire.
However, if climbing traction and cornering performance are at the top of your buying criteria, you’re better off looking at knobby tires such as the Panaracer GravelKing SK and WTB Resolute.
Schwalbe G-One RS result
Schwalbe’s latest gravel tire has withstood the worst conditions I’ve encountered. The carcass is supple and snappy, and the semi-slick tread performs well over a wide range of gravel road conditions.
The G-One RS is a better one-quiver gravel race tire than many of its peers and the width range is suitable for hard to medium-thick gravel terrain.
