The 32-inch trend is gaining momentum: Schwalbe is officially entering the market for this new wheel size. Starting in April 2027, the G-One RS Pro and G-ONE RX Pro gravel tires will be available in 32 inches—in widths of 50 and 55 millimeters, respectively. Matching tubes will also be available.

But it doesn’t stop at gravel: Schwalbe has also announced various 32-inch mountain bike tires for April 2027. The tire manufacturer plans to release details about the models at a later date.

This move doesn’t come as a complete surprise. The 32-inch size has been under discussion for months and has garnered additional attention thanks to early racing successes. One particularly notable example: Robin Gemperle won the Unbound XL on 32-inch prototypes of the G-ONE RX Pro.

Schwalbe sees the main advantages of 32-inch tires in riding stability, traction, and comfort. After extensive testing, the difference compared to smaller wheel sizes is clearly noticeable, explains Felix Schäfermeier, Head of Product Management at Schwalbe.

The key point for mountain bikers: With the announcement of the 32-inch tires, Schwalbe is making it clear that this development isn’t limited to gravel. Schwalbe plans to announce which mountain bike models will actually be available at a later date.
