Schwalbe’s G-One RX Pro is a new addition to the brand’s highly rated gravel race tyre line, which has been updated for 2025.
It features a new tread pattern claimed to balance speed with performance in rocky and muddy conditions, paired with a construction said to increase puncture protection and reduce rolling resistance compared to the previous G-One tyres.
In testing, the G-One RX Pro has proven capable in pretty much all conditions and is surprisingly speedy. There’s very little to criticise.
Schwalbe G-One RX Pro tyre details and specifications
The G-One RX Pro sits alongside the G-One R Pro and G-One RS Pro, with the three forming Schwalbe’s top-of-the-line gravel race tyres.
The G-One R Pro is the brand’s all-rounder tyre, with the G-One RS Pro aimed at hardpack – the G-One RX Pro is essentially a souped-up G-One R Pro.
It has the most aggressive tread pattern of the three, and at first glance, looks more reminiscent of a winter tyre than a summer one.
What Schwalbe describes as its “boomerang-design” centre tread is designed to offer low rolling resistance, with teardrop-shaped intermediate knobs either side of the boomerangs, which are claimed to improve structural support under load.
On the edge of the tread, you’ve then got alternating bigger teardrop and rectangular knobs, which Schwalbe claims improve grip and stability when cornering quickly on challenging terrain.
They feature Schwalbe’s new Race Pro construction, which has been developed to offer lower rolling resistance and improved rider comfort, while boosting puncture resistance. This replaces the Super Race construction found on the outgoing G-One tyres.
The carcass uses a 67 TPI (Threads per inch) casing and three-layer sidewalls, but has been widened, along with the V-Guard vectran puncture-protection belt.
The Addix race compound has also been tweaked, with Schwalbe claiming a 10 per cent reduction in rolling resistance and improved grip on the shoulders.
The G-One RX Pro is available in four sizes for 700c wheels – 40, 45, 50 and 55mm in ‘Black’ or ‘Transparent Sidewalls’ (tanwalls).
The 50mm transparent tyre on test is claimed to weigh 615g and came in at 617g on my scales. That’s lighter than the Pirelli Cinturato Gravel M, which weighs in at 706g, but heavier than a Vittoria Terreno T50 at 590g (both in an equivalent 50mm width).
Schwalbe G-One RX Pro tyre installation
I set the tyres up tubeless on a set of Fulcrum Rapid Red 500 wheels on my Niner RLT 9 RDO gravel bike with Muc-Off sealant.
The tyres were very easy to install onto the rims – almost disconcertingly so (there were barely any popping noises of the bead seating onto the rim), and both sealed at 25psi / 1.72 BAR using only a track pump.
The Fulcrum rims have a 23mm internal width and the tyre measured 48.01mm at 25psi / 1.72 BAR – rather narrow.
I then moved the tyres onto a pair of DT Swiss GRC 1400 Dicut wheels on a 3T Extrema Italia. The tyres were tougher to install here – I needed to use tyre levers to pry both beads onto the rim and I had to manipulate the tyre carefully to get it to seat with a track pump.
These rims have a 24mm internal width and the tyre measured 48.52mm at 25psi / 1.72 BAR – again, on the narrow side.
Schwalbe says it designs this particular tyre around a 25mm internal rim width, which explains why the tyre was undersized on my two test rims.
How I tested – wide gravel tyres
For this loosely titled ‘wide gravel tyres’ test, I pitted four 50mm tyres against each other.
This included two mixed-terrain options (Vittoria Terreno T50 and Schwalbe G-One RX Pro), hardpack rubber (Pirelli Cinturato Gravel H) and a tyre that straddles the line between gravel riding and cross-country mountain biking (Continental Terra Adventure).
Having conducted many tyre reviews for BikeRadar, I’ve developed a methodology for my testing.
After being weighed, each tyre was set up tubeless and tested on the same Fulcrum Rapid Red 500 wheels on a Niner RLT 9 RDO gravel bike, as well as at least one other wheelset on a different bike to reach a definitive judgement on how easy or difficult they are to install, and how wide they inflate.
Each tyre was subjected to a mixture of short and long rides across a range of surfaces, in both wet and dry conditions. All of the tyres were tested on a 70km control loop in the flint-infested Chilterns, before being tested in at least two other environments to get an idea of what conditions the tyre excels in – because the perfect gravel bike tyre for every terrain type doesn’t exist.
The tyres were assessed for rolling resistance, grip, puncture protection and value for money across both wet and dry surfaces on varied terrain. I’ve ridden each tyre for at least 500km, and while that’s not enough to comment definitively on durability, it has given me a flavour of what you can expect.
Since the tyres occupy different genres, I’ve drawn comparisons between them where I can, but I’ve also drawn on my wider experience with other tyres outside this group test, making more pertinent comparisons where applicable.
Schwalbe G-One RX Pro tyre performance
I tested the Schwalbe G-One RX Pro tyres through unseasonably dry conditions around my usual trails in Bristol and the Chilterns in the UK, as well as a day trip to the Salisbury Plain.
After some experimentation, I settled on running 25psi / 1.72 BAR for the front and 27psi / 1.86 BAR out back for my 74kg weight.
I found these pressures were suitable for all of my off-road exploits, although they were a little squirmy on the road – but this was a compromise I was happy to make.
The first thing I noticed about the G-One RX Pro was how fast they felt for an all-terrain tyre – there’s a night-and-day difference between these and the Vittoria Terreno T50, and I think they just pip the Pirelli Cinturato Gravel M.
They don’t feel quite as fast as a hardpack-specific tyre, such as the Pirelli Cinturato Gravel H though, and I validated this opinion by testing both tyres on Salisbury Plain, famous for its American-style smooth hardpack tracks.
Independent testing from BicycleRollingResistance.com found a 45mm Schwalbe G-One RX Pro generated 18W of rolling resistance at 33psi / 2.28 BAR.
That’s significantly less rolling resistance than a 45mm Pirelli Cinturato Gravel M (21.7W at 31psi / 2.14 BAR) and although not an apples-for-apples comparison, better than a 50mm Pirelli Cinturato Gravel H (21W at 31psi / 2.14 BAR).
In theory, that makes for a seriously speedy tyre, but it’s important to note these tests were carried out on a steel drum in a laboratory and not in the real world, which may be why I didn’t feel the G-One RX Pro rolled as fast as the Cinturato Gravel H.
In any case, the G-One RX Pros impressed on pretty much every surface I tested them on, from the root-infested Chiltern trails to aggressively rocky sections around Bristol. They do everything really well.
That extended to wet and muddy terrain, too (albeit in summer conditions), and the G-One RX Pros were unfazed by the odd mud patch.
The only type of terrain I was able to catch them out on was on loose, steep climbs, where I thought the tyre lost traction more easily than the Pirelli Cinturato Gravel M and Vittoria Terreno T50.
I’ll take that for their top performance everywhere else, though.
That performance potentially comes at the expense of long-term durability, however. I swapped the tyres over to the second wheelset at the 530km mark, and noticed two cuts in the rear tyre and one that had gone through the carcass.
On the front tyre, there was a thorn that had fully pierced its way through, but the sealant had done its job and plugged it.
There may well be an element of bad luck to this, but it’s something I can’t ignore. I couldn’t detect any loss of tread height on either tyre.
In terms of value, the G-One RX Pro is not a cheap tyre. It's dearer than the Pirelli Cinturato Gravel M in the UK and mainland Europe, at £64.99 / $84.90 / €72.90 / AU$99.95, and the Vittoria Terreno T50 at £54.99 / $58.95 / €58.95 / AU$72.99.
They justify their premium over the Terreno T50s with their significantly improved overall performance, however. The Terreno T50 does everything well, too, but never excels.
It’s a close call between these and the Cinturato Gravel M. On the one hand, the Cinturato Gravel Ms offer better puncture resistance and durability, and measure wider than their nominal size (a good thing if you have the clearance), but I think the G-One RX Pros just pip them for outright speed and they’re significantly lighter, too.
Schwalbe G-One RX Pro tyre bottom line
Schwalbe’s G-One RX Pro tyres are a seriously impressive addition to the brand’s top-of-the-line gravel offerings.
They perform brilliantly on almost all terrain and could probably be used all-year round, outside of the thickest mud, where a specialist tyre will perform better.
These are speedy and grippy tyres, although it’s important to note they’re positioned more as race tyres, which is something to consider if durability and puncture protection are your top attributes.
Alongside the Pirelli Cinturato Gravel M, the Schwalbe G-One RX Pro should go right to the top of your list if you’re after a premium mixed-terrain gravel tyre.
