Q & A


Although the Castelli Aero Race 5.0 jersey is a significant leap forward in aerodynamics and weight, Castelli have chosen to keep the 4.0 model in the line because it's one of the most comfortable all-around jerseys they have ever made.

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.
