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, snug fit, perfect cut
rating

My first pair of Castellis, and I'm a believer!! About me I'm 5'9, 168 lbs, with (I think) average thighs.... I bought the Large size and they are snug but not too tight. The shoulder straps feel a bit snug at first, but once on the bike, and after a few wearings, the fit is perfect for me. As some have mentioned the length on the shorts may be a BIT on the short side compared to some others, but I like it, I don't care for some shorts today that seem to hit your knees, so this may be a personal choice. The cut in the front of the shorts is on the lower side which is great for mid-ride nature breaks (as Phil and Paul would say - ha ha ha). All in all, a great investment, and I'll definitely be putting this on my Christmas wish list. More color options would be nice, but that's a minor nit for a great pair of bibs. Get yours now!

These are very comfortable bibs. I have two pairs. I prefer these to non bibs. They sit in place and dont cause chaffing.

Great Overall Fit and Value

This is my first time in Castelli and I am a believer!!! About me I'm 5'9, 168 lbs, 32 inseam, average thighs. I bought a size L and they fit snug but not too tight.... On the bike you barely think about them. Very comfortable, especially in the riding position. While I agree with others that the length may be a bit shorter than some other shorts, I like it.... they DON'T hit the knees like some shorts seem to, which I don't like. Also the front of the bibs is on the lower side, which is a good thing for when you need to take a nature break (as Phil and Paul would say - ha ha!). Overall, a great value - highly recommended!

I wear these bibs 3 times a week year-round with a local cycling group. I love the fit (snug, but not too tight) and light feel of the fabric.

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!

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.

You have to remember to order a size larger then you need since these always run small. I didnt and had to reorder.

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
rating
by Shawn

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
