Castelli has applied the Rosso Corsa treatment to its gravel range for the very first time with the launch of the Unlimited Speedsuit and Unlimited Pro 2 Jersey.
The Rosso Corsa label is only applied to Castelli’s highest-level products, each representing the pinnacle of technology and innovation for athletes who demand the ultimate in aerodynamics, comfort, and performance.
The Unlimited Speedsuit and Pro 2 Jersey take everything Castelli has learned from years at the cutting edge of road racing and applied it to gravel.
The Unlimited Pro 2 Jersey, which also forms the upper part of the Unlimited Speedsuit, provides a close-to-body, aerodynamic fit, with a CFD-optimized shoulder fabric and seam construction designed specifically to reduce drag at high speeds.
The Air_O Stretch body fabric strikes an optimal balance of breathability, comfort and performance, whilst providing UPF 30 protection and blocking 97% of all UV rays. A rear pouch has also been integrated to keep 1.5L hydration bladders and hose loops stored safely and securely, complimented by three open pockets and a zippered security option.
The Unlimited Speedsuit pairs the Unlimited Pro 2 Jersey with Free Aero Race S Bibshorts – Castelli’s fastest and most-comfortable Bibshorts to date. The Shorts are constructed from an aerodynamic Forza2 Stretch fabric, delivering a 3% decrease in CdA, and feature a Progetto X2 Air Seamless seat pad, providing comfort on even the longest of rides.
The Shorts have been optimized for gravel by adding nutrition pockets to the front, central quad position of the leg, allowing quick and simple access to gels and bars whilst eliminating the aerodynamic drag that side pockets generate.
Castelli Global Brand Manager Steve Smith said: “With the popularity of gravel continuing to grow and the racing getting increasingly faster, the time was right to take all our Rosso Corsa knowledge and experience, and take it offroad.
“Feed zones in gravel racing have become increasingly risky and stressful, but with our Unlimited Speedsuit incorporating hydration pouches and nutrition pockets, riders should be able to fly through them risk-free.
“The Unlimited Speedsuit and Unlimited Pro 2 Jersey are just as fast as they are functional; both are the result of over a decade of relentless innovation in aerodynamic efficiency.”
The Unlimited Speedsuit’s unrivalled characteristics have already been race-proven. Castelli Spirit of Gravel Cabal rider Rob Britton wore a prototype to victory at the 2025 UNBOUND XL.
He said: “I received the Unlimited Speedsuit the day before UNBOUND, and as well as fitting really well, the leg pockets worked a charm – nothing moved around – and the hydration pocket was dialed. I was also able to replace the bladder quickly during the race.
“My favorite thing about this suit is that it’s comfortable, as well as being super fast. I’ve used it in nearly every race since my UNBOUND win and it’s definitely progressing what’s possible in gravel racing.”
The Unlimited Speedsuit is available in two colorways: Vivid Orange/Hot Sauce-Black and Mango Mojito/Black/Ivory.
