Schwalbe G-One Allround Review: The Best All-Round Gravel Tire for Bikepacking?

What Is the Schwalbe G-One Allround?

The Schwalbe G-One Allround is a tubeless-ready gravel tire designed for mixed terrain — part of Schwalbe's broader G-One family, which ranges from the speed-focused G-One Speed to the aggressive G-One Ultrabite. The Allround sits in the middle: a closely spaced centre tread that transitions to more pronounced shoulder knobs, built to handle both tarmac and gravel without demanding a terrain commitment upfront.

It's available in 35mm, 40mm, and 45mm widths, in both folding and tubeless-ready (TLR) versions. The version tested here is the 40mm TLR with MicroSkin casing and Addix compound — the configuration I recommend for most riders.

How I Tested the G-One Allround

I've put 4,200 km on this tire across five countries — France, Spain, Portugal, Germany, and Austria — over multiple trips spanning two years. Conditions included alpine passes, Iberian gravel tracks, Atlantic coast roads, Portuguese cobblestones, and Pyrenean doubletrack. I've run it both unloaded and fully loaded with bikepacking gear.

I also run a comparison reference: every terrain section was ridden before or after on at least one other tire (Teravail Rampart, WTB Resolute, Continental Terra Trail) to ensure the observations are relative, not just descriptive.

On Tarmac and Hard Pack

The G-One Allround is not a fast tire on tarmac. On long paved climbs or into headwinds, you'll feel the rolling resistance — it's noticeably slower than the Schwalbe G-One Speed or Continental Terra Speed. What it does deliver is predictable, stable tracking: no squirm, no wander, confident braking. On routes that mix 30–40% tarmac with gravel, that's a reasonable trade.

On hardpack and compact gravel, the closely spaced centre tread rolls efficiently and the tire feels planted. It accelerates quickly from this surface and holds speed well.

On Gravel and Dirt Roads

This is where the G-One Allround earns its name. The tread transitions smoothly from packed to loose surface — the kind of unpredictable mix you encounter every few minutes on a real gravel route. Shoulder knobs engage when you lean into corners without feeling vague or grabby. In wet conditions on limestone and shale, it maintained grip confidently.

What makes it good here isn't peak grip — it's predictability. The tire communicates clearly as conditions change, which matters more on long days than raw traction numbers.

On Technical and Loose Terrain

Here I'll be honest: the G-One Allround reaches its limits on genuinely loose or rooty terrain. The shoulder knobs are not deep enough to provide real confidence on wet singletrack, sandy switchbacks, or steep descents with loose surface. If more than two hours of your daily riding involves technical terrain, you'll want the Schwalbe G-One Ultrabite, WTB Resolute, or Maxxis Rambler instead.

Loaded Touring Performance

Under full bikepacking load — handlebar roll, frame bag, rear rack — the G-One Allround stays composed in a way that lighter-casing tires don't. The MicroSkin casing is stiff enough to handle extra weight without sidewall fold or vagueness. Over three weeks of loaded riding in the Pyrenees, I never once questioned the tire's integrity. That's the real test.

"It's the tire for riders who want to think about their route, not their rubber."

Schwalbe G-One Allround Durability

Over 4,200 km, I had one puncture that sealant couldn't seal — a piece of wire, which defeats most tires. The tread wore gradually and evenly. I retired the rear at approximately 3,000 km due to centre tread wear; the front was still usable at trip end.

The MicroSkin casing showed no cracking or sidewall delamination. Tubeless setup was straightforward on DT Swiss rims — first-try bead seat with a floor pump, no compressor needed — and pressure loss between rides was minimal (1–2 psi over a week).
