Bontrager Aeolus XXX 4 Tubular Road Wheel

Aeolus XXX 4

The do-it-all workhorse, a carbon road wheel with a 47mm depth that is fast and stable for everyday aero.

Crosswinds? Not so much

On the open road, wind comes from all different directions. That’s why we redefined a high-performance wheel to be one that does more than cut through headwinds in a wind-tunnel. Aeolus XXX is optimized for stability in real-world conditions, even the strongest crosswinds.

Confident all-weather braking performance

Confidence to ride your fastest requires absolute confidence in your ability to stop. The all-new Laser Control Track massively improves braking performance for stopping power directly comparable to alloy rims, even in wet conditions.

Ultralight American-made carbon

From a flat sheet of carbon to an advanced aero wheel, all in Trek’s Global headquarters in Waterloo, Wisconsin, USA. OCLV XXX carbon combines premium materials and high temperature resins with industry-leading domestic manufacturing.

All-new wider shape

Aeolus XXX benefits from a wider 21mm internal rim and all-new shapes optimized for each depth and intended use. The result is that classic Aeolus ride quality with best-in-class aerodynamics and stability at all three rim depths.

Superior aerodynamics

Unlike many of its competitors, Aeolus XXX is optimized for aerodynamic performance in wind conditions of all types. We designed and tested over 10,000 shapes to ultimately land on three depths that lead the industry for speed, stability, and weight.
