Schwalbe G-One RX Pro Review – Fast Gravel Tire for Rough Terrain

Schwalbe G-One RX Pro – English Overview

Let’s talk tires – specifically the latest addition to Schwalbe’s gravel lineup: the G-One RX Pro. The name already sounds fast, and that’s exactly what this tire is meant to be. First introduced in fall 2024, I’ve had the chance to ride it throughout spring 2025, covering around 1,500 kilometers. That gave me a solid impression of what this tire can do – and how it sets itself apart from others in the range.

A Brief Word on Schwalbe – Race Proven Heritage

My first experience with Schwalbe in the gravel world dates back to 2019, when I rode the original G-One Allround in 35 C. At the time, that was considered a “big” gravel tire – and one of the first purpose-built for the genre. Since then, I’ve ridden Schwalbe tires on and off and was generally happy with them.

With the gravel boom, however, many strong contenders from other brands emerged – and in many ways, models like the Allround or Bite began to feel a bit outdated. But Schwalbe wasn’t asleep at the wheel: over the past two years, they’ve introduced three new gravel tires, each designed for specific terrain – the G-One R, RS, and Overland. Today’s focus: the brand-new RX Pro, pictured above.

The RX Pro on Dirt – Schwalbe’s Go-To Tire for Rough Terrain

The RX Pro feels like Schwalbe’s answer for riders looking for a bit more tread – or needing it. While the company hasn’t officially stated this, to me it seems clear: the RX Pro is positioned to replace the older Ultrabite. That tire had a pretty aggressive tread pattern with large, chunky knobs – a bit too much for my mixed riding, where long stretches of pavement lead to gravel trails.

Still, the Ultrabite had its fans – and the RX Pro now builds on that legacy in a smarter way. Compared to the R, RS, or Overland – all of which feature low to medium tread – the RX Pro stands out. It’s more aggressive, with wider spacing between the knobs and a clearly off-road-oriented design.

You can tell what this tire was made for at a glance: grip, and lots of it. The center features triangular knobs for forward traction, while the pronounced side lugs deliver secure cornering. It’s the kind of tire that seems to shout, “Take me off-road!”

First Impressions – Bumpy Start, Strong Finish

As mentioned above, I was never fully convinced by the old Ultrabite – mainly because I tend to avoid heavily treaded tires. They often feel unbalanced between on-road and off-road use. That’s actually what I loved so much about the Overland: a true all-rounder you could leave on your bike no matter where you’re headed.

Still, there’s a first time for everything. So, I mounted the RX Pro – which, like every Schwalbe tire I’ve used, went on in record time. Two or three minutes per wheel, and done. Especially for wider tires, Schwalbe makes mounting ridiculously easy.

Sharp-eyed readers might notice I ran the RX Pro with tubes. Not because I flatted – I just have too many bikes and swap tires too often. Going tubeless every time would be a mess. If this were my only bike? Sure, I’d run tubeless. But even with tubes and 2.0 bar of pressure, I’ve hammered this tire across rocks, roots, and rubble – no issues so far. Knock on wood.

Back to the actual ride feel. My honest first impression?
Not great.

Okay, maybe that sounds dramatic – but we’re talking about gravel tires here, so let’s allow a bit of flair. My cockpit felt like a jackhammer, and the noise? Let’s just say I sounded more like a fighter jet than a gravel bike. I even thought my headset might be loose – that’s how harsh the vibrations were during the first 50 km.

But then something changed.
Around the 150 km mark, the noise on tarmac dropped noticeably. It seems like the knobs just needed to bed in. And off-road? That’s where the RX Pro really comes into its own. The mud-shedding ability is excellent thanks to the wide knob spacing. Once the ground firms up again, the tire clears quickly and keeps rolling. In corners, it offers noticeably more control than the RS or Overland – it almost feels purpose-built for messy, technical terrain.

Still, my original concern remained: asphalt performance. Even here in Switzerland, with its stunning gravel options, paved stretches are part of most rides. Whether it’s getting to the trail, connecting two sections, or heading home – I need a tire that can handle tarmac without feeling sluggish.

And here’s where the RX Pro really surprised me – in a good way. On pavement, the tire feels surprisingly fast. Not just subjectively either – I checked the data from Bicycle Rolling Resistance (BRR), and sure enough, the RX Pro performs exceptionally well. The only tire ranked higher was the P Zero Race TLR SpeedCore 40 – a full-on road racing tire. That sealed the deal for me.

I suspect Schwalbe achieved this with a smart combo of compound and knob layout: the central knobs are all level, creating a smooth rolling surface with minimal resistance. Hats off to them.

RX Pro vs. Overland – Which One Fits Your Ride?

The Overland has long been my go-to Schwalbe tire. A solid all-rounder that handles everything from tarmac to forest roads – and almost as quiet as the RS Pro, despite having more grip. So how does the RX Pro compare?

It’s noticeably faster and about 70 g lighter. It’s not entirely silent on pavement – you do hear it – but it’s miles quieter than, say, an Ultradynamico Mars. Not as stealthy as an RS or Overland, but still well within what I consider comfortable. If I had to choose right now, I’d go with the RX Pro. The speed advantage is real, and the bit of hum is totally manageable.

What both tires share:
– Easy tubeless setup
– Excellent puncture resistance (almost identical in BRR’s testing)
– Overall reliability

When it comes to durability, I’d give a slight edge to the Overland – it spreads the load over more, smaller knobs. A fun fact here: Josh Allgeier rode from Germany to South Africa on two sets of Overlands without a single puncture – around 20,000 km in total!

Tested at the Unbound Gravel Race 2025

Here’s a fun little badge of honor: at Unbound 200, the biggest gravel race in the world, the RX Pro took both 1st and 2nd place. The winner ran an RS Pro up front, while the runner-up used RX Pros front and rear.

Looks like the pros agree: if you’re heading into rough terrain, the RX Pro is currently one of the best options out there.

Strengths & Weaknesses – The RX Pro at a Glance

👍 Pros
✔️ Confident ride feel on almost all surfaces
✔️ Outstanding grip off-road, while still fast on tarmac
✔️ Surprisingly quiet after the knobs wear in
✔️ Excellent mud clearing in clay and wet terrain
✔️ Comfortable and resilient

➖ Neutral
➖ Would love to see wider versions (e.g. 2.1″ or 2.25″)
➖ MSRP is €75 – but street prices around €50 feel fair

👎 Cons
❌ Not the lightest tire – but that’s expected with this tread

Final Thoughts – Who Is the RX Pro For?

The Schwalbe G-One RX Pro is exactly what Schwalbe promises it to be: a rugged, high-traction gravel tire for riders who like it dirty – in the best way possible. And they really nailed it.

If your rides include a lot of rough terrain but you don’t want to completely sacrifice road performance, this tire should be on your radar. It’s durable, surprisingly fast, easy to mount, and available in common sizes.

And for those of you who made it all the way to the end… let’s just say: Schwalbe might have another trick up their sleeve later this summer 😉
