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.

    39:24|
    They were just two kids from Wortegem, riding bikes after school, never dreaming they’d one day end up in the pro peloton together.In this episode of the Castelli Podcast, we sit down with Belgian sprint sensation Tim Merlier and his lifelong friend and trusted lead-out man Bert Van Lerberghe, a duo bonded by years of shared rides, muddy cyclocross circuits, and quiet ambition.From their humble beginnings to the world’s biggest races, Tim and Bert take us inside their journey—through the chaos of sprint stages, the grit of gravel racing, and the deep trust that powers their performance in the pro peloton. They open up about what it means to represent Belgium, the Castelli gear that gets them through the toughest days, and the unspoken connection that only two decades of friendship can build.This is more than a story about speed.
