    Details

    It’s all in the name.

    Castelli’s Free Aero Race Bib Shorts hide their assets in their name. Namely, free speed, aerodynamics, and race-oriented. The Free Aeros utilize a variety of surface textures, fabrics, and time in the wind tunnel to deliver a claimed 10-watt savings at 50kph. This may not seem like much, but those savings add up over even a two or three hour ride, and could mean the difference between enough power for a sprint and pedaling lamely to the line.

    At the core of the shorts sits Castelli’s Progetto X2 Air chamois, with one minor-but-crucial improvement —a softer face fabric. You get all the support and chafing resistance you expect from the Progetto, but it’s a bit kinder to your skin now. We’d be remiss to not mention the lightness of all of the fabrics in the Free Aero Race, in part because they’re comfortable and airy on even the hottest days, but also because you’re going to want to apply a bit of sunscreen at the leg bands.

    • Claimed savings of 10 watts at 50kph due to aerodynamics
    • Progetto X2 Air chamois
    • Giro Air leg bands stay in place without the use of silicone

    Very comfortable bib shorts

    • Familiarity: I've used it several times
    • Fit: True to size

    Find your dimensions on the Castelli size chart and buy them. They have a very comfortable compression fit when riding. Like most high-end race-fit Castelli clothing, they are designed for riding and not walking around or sitting in a cafe. I'm 5' 11", 32" waist and 38" hips. Medium fits perfectly.

    Don't wear well over time

    • Fit: Runs small
    • Size Bought: small

    At first, I absolutely loved these bib shorts, but even with careful handling...always washed in a mesh bag, cold water, drip dry, etc...they just didn't hold up. The fabric on the thigh area on both my pairs started to disintegrate, lost the color and became see through. The leg grippers lost their elasticity pretty quickly. For the price of the shorts they should last longer than one riding season. Disappointed.

    Same exact thing happened to me. I bought four pairs and took great care of them. The thigh panel pretty much disintegrated. Would have been nice to get a warranty replacement. At $199.00 a pop that's $800.00 worth of what I thought was a high quality product down the drain. I've purchased at least $2,000.00 worth of Castelli product and these were great for a time but in the end proved to be a bad investment. Hope the newer versions are better.

    I love the latest version of these bib shorts with the re-enforced seams at the crotch (addressed problem from previous model).

    I have two of the prior model and purchased two of the latest model in November 2015 that have the Carré hem-less straps.

    Castelli addressed the weak seams at the crotch but introduced a new flaw in the hem-less straps by using the Carré material.

    The straps should be laser cut during production to fuse the edges otherwise the material fails overtime like both of mine.

    Any slight imperfection will lead to material failure. When I received both of mine, I saw slight nicks in the curved edges but didn't bother to return them until a month later when the tiny nicks got bigger. It's now 5 months later and one has completed separated. See photos.

    Same issue as others

    • Familiarity: I returned this product before using it
    • Fit: Runs small
    • Size Bought: Medium

    I have two pairs of Body Paint in size medium and love them so I thought about trying the Free Aero. I was surprised that they were considerably smaller than the Body Paint. I could fit into them but they were a bit tighter than I like. Fit aside the real reason for return was they had the issue in the front of the chamois where it wouldn't lie flat. It appears a portion of the chamois material was folded over and sewn in place. It was only on one side, the other side was fine. So back they went before using them. A bit disappointed.

    My favorite bib shorts

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: medium

    I own a variety of Castelli bibs, the Evoluzione (Kiss 3 pad), Endurance X2 (bibs and shorts with X2 Progetto chamois), and these Free Aero bibs. While the others do the job, but the Free Aero bibs are the most comfortable and best performing bibs I own. They are comfortable, fit perfectly, the X2 Progetto chamois is just awesome. While I've typically chosen to save $$$ and get the Endurance X2s, I prefer the Free Aero bibs.

    best Bibs I own

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: medium

    this is the second pair of these I have. Bought my first pair last year and I fell in love. The chamois is super comfortable. I have done numerous centuries in them and rode them hard all year. They still look great, no pilling or broken seams. sizing is typical European so if you like extra room you may want to size up

    Really wanted to like these bibs

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

    I really wanted to like theses bibs. I loved all the materials, the leg bands, the shoulder straps. However, after a few uses/washes the first pair I had developed a problem in the chamois. Part of the chamois pad had become loose between the liner and the lycra near the front of the pad. One email to CC and they quickly and easily sent me a new pair, no problem. The next pair arrived and they had the same issue going right out of the bag. There is no way that there should be loose padding shifting around in the chamois. I definitely feel like Castelli has an issue here. Five stars for CC's customer service though. They are always easy to deal with.

    Unfortunately I have had the same problem. Love these shorts, chamois is awesome...until, that is, the front somehow comes loose and folds over between the short material and the chamois cover. Has to be a problem in production, just hope it gets resolved. And yes, Backcountry/Competitive are great to deal with on warranty issues. Always five stars there.

    Mine are the same way. I guess they all suffer from this issue. I kept messing with mine until I got it to lay somewhat flat and even. Now I don't really notice it much, but I still know its there and this definitely shouldn't happen. Whenever Castelli gets this issue ironed out, I'd love to get a second pair. The materials and design are awesome. Kudos to Competitive cyclist for excellent customer service!

    Bought 2

    • Familiarity: I've used it several times
    • Fit: True to size
    • Size Bought: M

    I am new to cycling. I wanted to get a decent pair of shorts so that I had the best chance of enjoying the sport. These have not let me down. They are comfortable, look good, and fit perfectly. I'm 5'7

    Oh they could be a little cheaper...but oh well

    Glad I bought them

    • Familiarity: I've used it several times

    I researched bibshorts after my previous two pair began to cause saddlesores. To be fair, I did have the last ones (not the same manufacturer) a year or two longer than they were intended to live. They began to loose their compressive character, and I should have been a bit more observant about fit. Free Aero's were on sale and I gave them a try. Started with one pair but after 1 ride jumped on the second as the chamois was superb and the compressive fit exactly as described...they disappear on you. All other reviews from here were spot on including smallish sizing, so that really helped me. Saddlesores disappeared after a reasonable period of time and meticulous hygiene attention. Let's see how long they live! Good deal on sale if you can get it.

    I'll never bother with any other bibs

    • Familiarity: I've used it several times
    • Fit: Runs small
    • Size Bought: xl

    These are my first bibs after many pairs of shorts.
    They are easily more comfortable than my best shorts. I first used them in a 75 mi race and they just disappeared. I never gave them a thought, they just sat there and did their job.
    The straps are a little snug, but I do have a ridiculously long torso.
    I'll never consider any other bibs. They are pricey, but time in the saddle is valuable and these have ruined me for anything lesser.

    Super comfortable, great chamois

    • Familiarity: I've put it through the wringer
    • Fit: Runs small

    Update after numerous rides... New favorite bibs, mainly because of GREAT chamois, super comfortable, no chafing after back-to-back 101/65-mile rides in high heat and humidity, just the right amount of padding, etc. New straps, leg bands are different but I found both really comfortable. Redesigned crotch area is MUCH improved. Last year's left no room for the obvious. Now, fit great. Agree with other review - typical Castelli sizing. I'm 5' 8", 155, order a medium. Wish they would do a Skratch Labs color way like offered last year.

    Super comfortable, great chamois

    1st ride

      Just got these and took them out for an 80 mile ride. I like the fabric on the shorts and the leg band better than the previous year's free aero bibs. I don't think I like the fabric at the top of the straps as much, but all in all I think they are an improvement from last year's model. Typical Castelli sizing. I'm 135 lbs and wear a medium. They fit well but are tight especially around the thighs.

      Free Aero Race - dimpled fabric

      As the name suggests, the Free Aero Race Shorts are designed to cheat the wind, reducing power output requirements by a claimed 10 watts at 50 kilometers an hour. The secret to these gains lies in how the shorts manage airflow across their multiple boundaries and textures — most obviously via the dimpling across the shorts' outer plane.

      Free Aero Race - back view

      The seat and front of the shorts both feature fabrics designed for durability and cooling breathability, respectively, and the entire body is 30% Lycra for a fit that strikes a balance between compression and unrestrictive movement. Castelli also included highly reflective details on the back of the grippers for extra safety.

      Free Aero bib straps - back

      Carré engineered lie-flat bib strap construction for minimal coverage, maximum comfort. Carré is a hem-less strap that lies virtually flat against your skin.

      The base layer is the Castelli Seamless Base Layer - and it is awesome. It looks really small when you take it out of the packaging but the fit is amazing. http://www.competitivecyclist.com/Store/catalog/search.jsp?q=Castelli+Seamless+Base+Layer&s=u

      Progetto X2 Air Chamois

      The Castelli Free Aero Race bib shorts feature a new softer surface fabric on the updated Progetto X2 Air seatpad. The innovative double V construction on the front keeps everything in place without compressing your stomach.

      Castelli Free Aero Leg Band

      The new Giro Air has the same perfectly flat, stay-in-place grip, but with less mass, which no doubt contributes to the claimed overall weight loss of 17 grams and definitely reduces the aerodynamic footprint.

      Castelli Free Aero Leg Band

      Is my ass crack going to show through these after a few months of uses? Just wondering if anyone has had these for more than a few months? The material looks great for breathability but i dont want to run into problems down the road.

      I have had these bibs for about 2 months and have washed them about 5-6 times. I just noticed that the front of the chamois has become dislocated and partially folded over inside of the outer fabric. What is the warranty and is there any way to get them replaced?

      Thanks

      I had really good luck with the Castelli warranty department. Chainlove/Steep and Cheap only offer 30 days, but I think that Castelli warranty is 1 year for workmanship problems. You have to send them in, and they will evaluate them and send you a replacement, if it is a workmanship issue.
