Q & A


The Castelli Free AR 4.0 jersey FZ is part of the Rosso Corsa range meaning it has been designed specifically for speed and performance. To bear the Rossa Corsa logo, a product must represent a categorical breakthrough in technology; so when you wear a Rosso Corsa product, you know you're getting an unfair advantage. Thousands of hours have been spent figuring out ways to save thousandths of seconds at every stage of the race. This dedication has always been part of the Castelli legend.

Like all jerseys in the Rosso Corsa range the Free AR 4.0 is lightweight, aerodynamic and a perfect fit. Castelli claim that the jersey saves approximately 12 watts at 40 km/h compared to a normal race-fit jersey. Combined with an excellent moisture management the Free AR is one of Castelli's most comfortable jerseys of the summer.

The jersey is easy to get on and off thanks to the full length zipper while the silicone gripper at the waist and Giro3 arm elastic guarantee a close fit for improved aero-dynamics. The jersey is finished with 3 rear pockets to give you east access to any essentials and reflective strips on the back to keep you visible in low light conditions.

Note: Castelli clothing is sized small, Tweeks Cycles recommend you select one size above normal for an athletic fit, or two sizes above if you prefer a more relaxed fit.
