Castelli Free Aero Race S Kit Men's Cycling Bib Shorts
The Castelli Free Aero Race S Kit Bib Shorts are their fastest and most comfortable race-focused shorts to date. They are at home in the turmoil of a fast-paced peloton, the Tuesday evening pace line, or the steady efforts of long, endurance training. Castelli's Forza2 stretch fabric offers precise and supportive comfort, moving smoothly with every pedal stroke. Forza2 is also aero-optimised, with a claimed percentage reduction in CdA of 3%, letting you get up to and hold speed with ruthless efficiency.
The bib straps are minimal, with a lightweight, flexible construction that delivers a barely-there feel and optimal breathability. Low-profile leg grippers keep everything in place, so you can focus on race tactics and interval splits.
Progetto X2 Air Seamless seat pad
A pro-level seat pad designed for maximum comfort during endurance training, interval sessions and the efforts of racing. Against the skin, a seamless skin-care layer feels luxuriously soft and reduces rubbing and abrasion. A saddle-shaped layer features progressive damping and support, with high-density foam and gel inserts ensuring total comfort throughout a ride.

About Castelli
At the front since 1876.
Castelli has been at the front of cycling apparel since 1876, founded in Milan as the original maker of pro race kit. From the first cycling jerseys to today's WorldTour-proven aero garments, the brand has spent nearly 150 years putting innovation onto the backs of the fastest riders in the world.
Castelli outfitted the first organised cycling teams in Italy and has been a constant presence in the pro peloton ever since. The Scorpion logo appears on more WorldTour podiums than almost any other apparel mark.
