Tested to perfection.

Castelli's Free Aero Race Bib Short is the result of four years of Pro-Tour abuse and constant refinement. The name is derived from the Free bib upper, a unique strap design which uses as little material as possible, keeping your chest free to avoid overheating. The sides and back of the short are made from Energia fabric, a highly elastic, stretchy material for totally unrestricted movement. Breathe micro fabric is used on the front panels for further breathability and moisture regulation.

At the saddle contact point, a tougher material called Action micro is used for wear and tear and tear and resistance. Underneath, the new Progetto X2-Air chamois uses a layer of multi-density supportive padding and a layer of soft, antibacterial fabric against the skin. Perforated cells allow it to breathe better than its non-Air predecessor for fast dry times and additional comfort.

The Free Aero Race Bib Short is available in Black/Black and Black/White.

Additional Features:

  • Seam-free inner leg
  • Giro3 single layer leg grippers
  • Progetto X2-Air chamois pad

Note: Castelli tops and bottoms are designed with a performance cut that often runs smaller than that of other manufacturers. Consider sizing-up one size to ensure a comfortable fit — e.g., if you normally wear a Medium, select a Large in Castelli. Feel free to contact us with any questions or concerns.

Great looking pair of bib shorts for long rides. Excellent feel and comfort. You may need to size up, I'm 5'11 and 175 lbs and large fits perfect.

Go 1 size bigger
by BobbyG
SC USA

I'm 5'11 190 lbs. I wear large in most cycling bibs or shorts. I followed the advice of many others & ordered XL. Perfect fit. They are comfy, cool, & stylish. The chamois is great for long rides. Too soon to say anything about longevity but was happy I bought these at % off. $ off brought them into the affordable realm for me. My only knock is the long tag in the rear.

You better order a size larger with these. Once I received the correct size, I kind of like them although you better get used to a new tan line.

Great Bib Shorts

I wore these shorts today on a 3 hour ride in 90 degree weather. They were awesome in the heat and I find them more comfortable than any of my other bib shorts.

I sized up from my normal Large size selection and purchased XL's. I am 185 lbs and 5'10.

Buy these bibs.
by Fossil Jack

Perfect fit (at 5'10 160 lbs. I can fit a medium, but usually wear a large). Excellent for extended distance as well as shorter hammerfests. Very comfortable chamois. The smallest of complaints is that the Castelli scorpion will start to disintegrate over time and use. But you can't go wrong, esp. if you can locate them on sale (it happens!). These were my go-to shorts for many of the 17,000 miles I rode last year.

Good Summer Bibs
by Triall55
Cycling Enthusiast
Laconia, NH

I have worn these bibs for 2 rides so far, one 24 mile's the other 28. I have not done a long ride yet but on these 2 ride's the shorts were very comfortable and the fit was right on. I'm 5'8 and 143 lbs and the Medium fit tight but perfect on the bike. I need to do a longer ride to be sure on the long distance comfort or I would have given 5 stars.

Fantastic Bibs
by Kevin C
Cycling Enthusiast
Vermont

These are great bibs - extremely comfortable and high quality material. Great chamois as well. They do fit very snug - I'm 6' and a very thin 140 lbs and the M is a pretty aero fit (I'm a size S in all other Castelli). My only complaint is that the inseam is a little short - wish the legs were cut an inch or so longer. Anyway, highly recommended.

Great Bib Short
by Shawn
Silverdale ,WA

Good bib. Size up as usual with Castelli. Im 511 and 81 kg and Xl is just about right. The only thing I would add to improve the bib is to beef up the fabric in the short where the chamois is stitched in. That where my last pair gave out

The best bib shorts I've owned

Review for Castelli 2014 Men's Free Aero Race Bib Short
7 of 7 customers found this review helpful.

The material used in these bib shorts is of very high quality. I have around 1000 miles in them and they've been washed numerous times (be sure to hang dry). All stitching has remained perfect and the material shows no signs of pilling. The leg grippers are thin, simple, comfortable and perform great. The mesh straps are airy and the feel of them disappears while riding. The Progetto x2 air chamois really completes the package. I've had issues in the past with chamois that have uneven edges (pod like areas) where they contact the skin. The ultra soft material of the Progetto X2 chamois is flat with any padding thickness variations taking place below the skin contact surface. I've worn these on several century rides and when paired with DZNUTS chamois cream have had no issues. These are and will continue to be my go to bibs for every ride over 60F. Just waiting for the right price to order more!

Most natural and comfortable bib I've owned in 38 years of riding
by Quadrifoglio

Review for Castelli 2014 Men's Free Aero Race Bib Short
1 of 1 customers found this review helpful.

After years of riding $100 bibs, I stepped up for these Castelli's back in January. Bought one pair. I now own four. The most comfortable chamois imaginable! Why do so many manufacturers make their chamois with corduroy ribs and such?! The chamois flexes naturally on the saddle and never feels bulky, yet also provides good comfort. My rides are typically 30-50 miles. They also have good protection up front and I experience no numbness as I have had with some other bibs. The compression on your thighs is firm, but not strangling (I'm XXL with 25 thighs) and the fabric warms up and the fit eases after just a couple of minutes. Excellent construction throughout. Nice bit of graphic flare without being too loud. Love 'em!

Great fabric, not so great fit
by ScottP
Cycling Enthusiast

First, the good stuff. The fabric is great - light, supportive, very breathable. The leg grippers are also well designed - somewhat mesh-like, so they're cool in the heat, and they allow some sunlight to pass through which minimizes the sharp tan line lines. Finally, the flat seams are comfortable and non-chafing.

Now the not-so-good, specifically, the fit. As others have mentioned, these run small, so you'll need to order one size larger than normal. And I did, yet they were still very tight in the quads (everywhere else was fine). The oddest part of the fit was the pad. There's an ample amount of padding at the rear of the pad, well beyond what would make contact with the saddle, and seemingly unnecessary. On the other hand, there's a distinct lack of padding in the frontal area. While some might this free sensation (they are called Aero Free after all), I found it uncomfortable after 50 miles in hot weather. Finally, the padding itself seems very thick (too thick) in the perineal area which hampers long-ride comfort.

As a point a reference, I have several top-end bibs by Assos, Nalini, Squadra and ViFra, none of which give me any problems, even on longer (100) mile rides. These Castelli's are distinctly less comfortable than all the others (some costing much less) and will likely be relegated to short races and club rides. Sad, since I have several Castelli jerseys and gloves and they're among my favorites.
