Schwalbe goes large with its first 32-inch gravel tyres – but where are the bikes to use them with?
The tyre industry is embracing the new standard for gravel, but it's taking a little longer to win over the rest of the industry, with just prototypes, custom one-offs and small builders willing to commit so far
Schwalbe is set to unveil its first 32-inch gravel tyres in April 2027, offering 50mm and 55mm widths. The move follows a rise in interest for 32-inch gravel bikes, with the initial models expected by autumn 2026. Testing indicates improvements in stability, traction, and comfort, with notable success on prototypes fitted to a Scott gravel bike ridden by Robin Gemperle. Gemperle commented that this larger wheel size perfectly suits gravel racing and Unbound Gravel.
Currently, smaller manufacturers like Colorado-based Mosaic are dominating the 32-inch market, with their titanium GT i55 32 bike. Other companies like Stinner, BTCHN, and Salsa have also released or announced 32-inch gravel frames and components. Major brands such as Specialized, Trek, Giant, and Cannondale are yet to introduce 32-inch gravel bikes, but they are expected soon.
However, the transition to 32-inch gravel bikes presents a challenge for smaller riders. A 32-inch wheel with a wide tyre measures over 80 centimeters in diameter, which could cause handling issues for smaller riders with smaller frame sizes. Wheel geometry needs to be adapted to maximize the benefits of a larger wheel size without compromising the bike's performance. The industry might need to wait a bit longer before seeing a broader range of 32-inch gravel bikes catering to all rider sizes.
