WTB and Stromm target aero gains with new gravel tyre project

Aero focus moves to the tyre

WTB has teamed up with Stromm to create aerodynamic gravel tyres featuring 'vortex generators', according to road.cc. The move lands in a gravel market where speed-focused design is becoming more visible, with the source pointing to Factor's recently launched Elara as another example of brands pushing aero concepts into gravel equipment.

The significance is less about one product claim and more about where the design conversation is going. Gravel racing has traditionally forced a balance between traction, comfort, durability, and rolling speed. If brands are now putting aerodynamic shaping into tyres, it suggests the search for marginal gains is moving beyond frames and wheels into parts of the bike that used to be discussed mostly through grip and puncture resistance.

That matters for racers because gravel equipment choices are increasingly being shaped by the full system, not isolated components. WTB entering this space with Stromm reinforces that aero gravel is no longer just a frame-design trend.
