Castelli Free Aero Race 4 Bib Short

The Free Aero Race 4 is a high-end bib shorts made for road bike racing. The design was created for speed, providing the best performance for cyclists with specific performance goals. Its aerodynamics have been greatly optimized. Since it is a performance bib and has been improved by the observations made by professional teams, it has been designed to give comfort on long rides. Do not forget that the pros drive 30,000 km per year, and that for them, an exit of 4 hours is not even considered a long exit. Thus, the Free Aero Race 4 bib shorts were created for racing at the highest level, but all its features make it an ideal cycling short, whatever your goal.

The 2019 model features a new leg gripper that still features a lie-flat raw-cut edge but now has vertical silicone stripes to keep it in place without restricting stretch. The updated seams improve the fit and make the shorts look even better. The bib straps allow the construction to stay cooler, lie flatter and are more durable. It features the new Progetto X2 Air Seamless seat pad with the softest surface fabric you've ever felt.
