KASPER ASGREEN | Gabba R Explained: Wind Tunnel Data & Aero Speed

In this final episode of the year, we explore the full story of the Gabba — one of the most influential innovations in cycling apparel history.

From a brutal Classics race in 2010 that changed how the peloton raced in cold and wet conditions, to the latest evolution, the Gabba R, this episode traces how a single idea became a category-defining product.

Recorded after a wind-tunnel session in Milan, this episode features Kasper Asgreen, who shares real-world testing insights from training and racing in some of the harshest conditions imaginable.

We break down the aero data, explain how the Gabba R can be faster than an aero jersey or even a road suit in certain positions, and dive into the technology behind its waterproof, breathable, and highly elastic construction.

Cycling history, marginal gains, and real performance — all in one episode.

Happy New Year, and enjoy the ride.
