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 Shorts
by C Buckley
Cycling Enthusiast
Austin, TX

These are great shorts, I only wish I had tried them sooner! The chamois is the feature that really makes these so nice, specifically the shape and the way the edges of the chamois are thin to minimize chafing. I have previously used the top model Pearl Izumi bib shorts for years and they performed ok but in the last few years my mileage has increased and I was getting more and more irritationchafing resulting in minor sores (especially in the Central Texas summer sweat season when everything gets soggy). These Castelli shorts rival the much more expensive Assos shorts in comfort and chamois performance. The only thing I would change would be to add a bit of length to the bib straps since I am tall and the size that fits my legships is a bit too shorttight from a length perspective ... it's not really a problem when in riding position but noticeable nonetheless.

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

Great, snug fit, perfect cut
by TeamAslan
Cycling Enthusiast

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!

Sizing Is Meaningless
by Anonymous
Cycling Enthusiast
Williamsburg, VA

First off, I am 5'11, 180 lbs. I admit that I am a bit heavier than my usual 165 lbs for reasons I won't bore you with. Losing the extra weight is a priority at the moment. That aside, this appears to be a nicely made, if rather pricey, pair of bib shorts. I say appear because I have yet to use them. The reason? The fit! I studied the sizing chart carefully and came away believing the XL would fit me fine. Wrong. I swear, trying to slip this thing on was like putting on a too small condom. It was so tight I could barely breathe. I don't know how much weight I'll have to lose to fit into this, but it could be at least 20 pounds.

My question for Castelli is who are you making these for? Eighteen year-old professional cyclists? Come on, calling this an XL is like calling a size 8 shoe a 12. And whoever came up with that sizing chart needs to get some real world experience.

Great Overall Fit and Value
by TeamAslan
Cycling Enthusiast

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!

The Castelli bibs are the most comfortable shorts I wear. I am able to ride for HOURS with no discomfort. I highly recommend Castelli bibs. They really do run small relative to their identified size.

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!

Go 1 size bigger
by BobbyG

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.

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

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