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.

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.

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.

Fantastic Bibs
rating
by Kevin C
Cycling Enthusiast

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

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

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!

Very comfortable, high quality bibs
rating
by Salemrider

I have had these bibs for the last two months and they are very comfortable, fit well. I was a bit concerned about the sizing, I'm 5 ft11 12, 210 lbs. I purchased the XXL and the fit is just right. Nice chamois, good ventilation, feels like you are riding naked but with support in all the right places. Very high quality materials and workmanship. I like the different materials used in the construction of these bibs, the right material in the right places, especially the shoulder straps, nice and flat. I will absolutely buy another pair. Western bike delivered them fast and the price was great. I can always count on great service from Western.

My preference for Castelli goes way back. Once you're dialed in, no need to break the chain. Free Aero Race Bib provides you all the details you'll find in more expensive bibs. Price point is relative to one's budget, but I've learned quality workmanship will drive higher return on investment for many, many miles.

The most comfortable bib shorts I have ever had. No pressure points, excellent chamois, and very durable. Latest purchase is my 4th pair, the first pair purchased is still in use and exhibits very little wear. WesternBikeWorks offers excellent pricing making these shorts a good value.

Review for Castelli 2014 Men's Free Aero Race Bib Short
3 of 4 customers found this review helpful.

I have many different bibs from most major vendors. I've used these bibs for about 1 year maybe 30 times. The stickers are all delaminating (most other manufactures have figured this out)--gentle wash, never used dryer. And, the pad is holding up okay. Frankly, I think Capo for same price point is probably a better buy, at least for me.....

Paid a little extra to get these shorts, it was well worth it. They work flawlessly and fit comfortably. I am 5' 11 185 and the XL fits great. I did not realize this is part of Castelli's Rosso Corsa line.
