Just as fast as racing naked.

While they already fit like a second skin, the Free Aero Shorts go a step further and incorporate dimpled fabric at the outer panels to move air much like the surface texture of a golf ball. The seat and front panels are constructed from a breathable fabric so you won’t overheat. Both fabrics are 30% Lycra, which lends a compressive quality to the fit to keep your legs rejuvenated. All the seams are flatlock stitched to minimize chafing.

The bib shorts are held in place by Castelli Carré straps. This design features breathable mesh that culminates in Carré fabric in a yolk over your shoulders. This keeps the straps tight, yet comfortable, against your torso to avoid unnecessary wind stifling bulges.

In subtle Italian style, the shorts feature Castelli red accents on the leg grippers, reflective squares on the rear of the legs and iconic scorpion logos.

Here's what others have to say...


Excellent quality!

  • Familiarity:I've used it several times

The product is of excellent quality in terms of material, workmanship, and design. I am about 5'-10"/165 lbs and bought a large. Normally I would buy a medium. The large still fits tight but is comfortable when riding because of the material. I have found with Castelli products you can easily select a size up and have a good fit.



  • Familiarity:I've used it several times

I have this bibs for less than 3 months ..Were great when new with tight fitting and compression feel...In less than 3 months have become really soft and they stretch too easily out of position...Not impressed for the cost..Chamois is great ..


Quadzilla Beware - Runs Small

  • Familiarity:I returned this product before using it

I usually wear a Large in Castelli bibs. I read the reviews and decided to size up and went with the XLs. These things are still too small and I'm 6'/190(33waist/32inseam) with muscular thighs/butt. I like my clothing snug/race fit, but these bibs are very constricting on the legs and crotch. If I went with the XXL, the length would be longer than I like. Really bummed...these things are quality material and well made.


Perfect fit and feel.

Im 6�3, 185lbs, 34/34 pants and this bibs fit and feel perfect. Nothing more to say :-)


awesome bibs

  • Familiarity:I've used it several times

This bibs are great but run smaller then other Casttelli ordered med but had to exchange for lg. The chamois is great and your butt will thank you. I have used them on three 30 mile rides and they performed very well.


Sweet Bibs

  • Familiarity:I've used it once or twice and have initial impressions

These bibs are freakin' sweet. Haven't used them a ton yet, but if your like me, you know a good thing when use it.
