32-inch by Schwalbe
The first 32-inch gravel bikes will hit the market at the start of autumn 2026 – now we're introducing our first gravel tires in the new size. We're launching the G-ONE RS PRO and G-ONE RX PRO models in 32 inches, in widths of 50 mm and 55 mm.
In addition to the gravel tires, we'll also be offering various MTB tires in 32 inches. All tires will be available from April 2027.
Available from April 2027
G-ONE RS PRO
50-686 and 55-686
G-ONE RX PRO
50-686 and 55-686
Feel the benefits
At Schwalbe LAB, we've thoroughly analyzed and extensively tested 32 inches to objectively assess the benefits for as many riders as possible. We were initially skeptical ourselves, but the tests clearly show: "Anyone riding on 32 inches feels a difference", says Felix Schäfermeier (Head of Product Management at Schwalbe).
SCHWALBE LAB
The Schwalbe LAB is the driving force behind innovation in the bike industry. Here we develop, analyze and test new technologies – always with the goal of setting new standards. Just like our recent MTB radial tires, which set a completely new benchmark in performance.
Results from our practical tests
- In practice, test riders experience noticeably more stable handling and an increased sense of safety.
- Schwalbe athlete Robin Gemperle won the XL category of the world's most famous gravel race, Unbound Gravel 2026, on prototypes of the G-ONE RX PRO. He says: "I still remember one observation clearly: compared to my normal tires, I quickly noticed I was faster through corners and had more control on every surface."
- Especially on varied, rooty and rocky terrain, 32-inch tires roll better. This provides more traction while also increasing comfort.
- This is what makes 32 inches interesting – the size opens up new possibilities across segments, not just for purely performance-oriented riders.
Assessment and outlook
Our gravel tires G-ONE RS PRO and G-ONE RX PRO will be available at specialty retailers from April 2027 – along with matching tubes. We're also working on additional 32-inch tires. We'll communicate specific model announcements and technical details at a later date.
