Castelli Free Aero Race S Men's Cycling Bib Shorts

The Castelli Free Aero Race S Bib Shorts are their fastest and most comfortable race-focused shorts to date. They excel in the elbows-out, high-speed exhilaration of a surging peloton and the lung-bursting efforts of training. Castelli's Forza2 stretch fabric gives 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 and flexible construction that gives a barely-there feel and allows optimal breathability. Low-profile leg grippers ensure everything stays in place, letting you concentrate on race tactics and interval splits. 

Progetto X2 Air seamless seat pad

A pro-level seat pad engineered for maximum comfort. A plush and seamless skin-care layer feels super soft against your skin and reduces the chances of abrasion and irritation. A saddle-shaped cushioning layer features high-density foams and perforated gel inserts, giving progressive damping and support precisely where you need it most.

Impressive Bib Shorts. Great compression right down to the knee. Usual very comfortable seat pad. Shoulder straps are a little short, so sizing is crucial. Good value for money against similar competitors.

I can thoroughly recommend these Castelli bib shorts. They are extremely well made, comfortable and supportive, thanks to the quality of the material, tailoring and fit in the shorts and padding. I have now used them on fast, flat club rides, as well as longer hilly, endurance routes. They also help the rider to remain cool whilst cycling on hot summer days, which is a major plus point! They are definitely my favourite and best quality cycle shorts, which I would happily buy again.

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.
