Description

Tomorrow's industry standard, today.

You'd be forgiven for thinking there's an echo in today's bib shorts market. It seems that Castelli's competitors are always exactly one year behind, suddenly developing the same innovations that featured on Castelli's previous models. So, with the release of the new Free Aero Race Bib Shorts, we're pleased to once again present tomorrow's industry standard, today.

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. Like with a golf ball or some deep carbon rims, these dimples manage the turbulent lamina of air that runs along the shorts' surface, preventing its premature release into pockets of drag-inducing dead air.

Castelli found itself unwilling to part with the Progetto X2 Air Seat Pad, so it returns with only one, minor change: its surface is softer, which means it now presents a more gentle face to your perineum. It retains its bacteriostatic properties, seamless construction, four-way stretch, and ventilating, perforated foam layer. The perforated viscous comfort inserts also enjoy an encore performance, so your sensitive areas will enjoy riding over all manner of terrain.

Those may be the only returning features of the previous model — not even the materials used were safe from Castelli's obsessive need to tinker. 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.

The bibs' wide open, non-stifling design also returns from the previous model, but the bibs themselves now comprise two materials. The straps are mesh 3/4 of the way up, but — like any good domestique — the mesh lets a yolk of Castelli's innovative Carré material summit your shoulders. Carré is a hem-less strap that lies virtually flat against your skin, so there aren't any wind-grabbing, stegosaurus ridges from bib straps bulging out of your jersey. The liminal seam between mesh and Carré is also reinforced, so you don't have to worry about any wardrobe malfunctions while hoisting the trophy on the podium.

Last year's model featured Castelli's upgraded Giro3 integrated grip bands at the hem, but it shouldn't surprise you at this point that Castelli has upgraded these yet again. 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. The new band is wider, almost equaling the length of a typical Euro-slammed road stem, and every square millimeter of the material acts as the gripping agent. No silicone gel print here.

The lower mass means the leg bands are also pretty transparent, which may initially be a turn-off, but will likely take off as it appears in the pro peloton. In this case, it's important to note that "pro" isn't short for "UV protection," so we recommend a bit of sunscreen applied a few minutes before suiting up. As a final touch, Castelli included highly reflective details on the back of the grippers for extra safety, just in case you get caught out at a time when sunscreen won't do any good.

  • Racing bibs for the discerning cyclist
  • Aerodynamic features for a claimed savings of 10 watts
  • Gently compressive material reduces long-mile fatigue
  • Lie-flat cuffs and bibs reduce drag from transitional ridges
  • Race chamois is lightweight but comfortable in long races
  • Castelli's tailoring is fit for professionals and recreationalists alike

I had to size up to a large (5'11 170lbs) but fit is good. Solid construction and appropriate padding. Great for long rides, racing. Truth be told these are more versatile and functional than Rapha mid level bibs. Would definitely buy more.

I wanted to like these, but they had enough mixed reviews that I returned them before riding in them. The chamois has a funny infold in the crotch, that seemed to flatten out when trying them on. I was going to give them a try riding, but then the pad seemed asymmetric, and did not cover my left ischial tuberosity except for the thinnest portion of the pad. I tried rotating the legs and repositioning the shorts, but nothing worked. When I took them off and examined them by folding the chamois in half, the two sides were different. For that reason I returned them and suspect this was a problem with quality control. Otherwise, I loved the fabric and thought the fit was great.

After riding with these for a season something weird happened with the chamois/pad. Floating around inside the chamois there is now a gel blob that can cause problems when it migrates to the wrong place. I've never had a pair of bike shorts do this and I care for all of my stuff the same way. Unfortunately I shelved these things and pulled out some older bibs in the meantime but they probably failed right around the 12 month mark. Otherwise nice fabric, good leg grippers and fit is a tad small (I wore large and I'm 5'10" 170). I was definitely hoping to get another season out of these things.

I purchased these as a hopeful step-up from the Velocissimo, which I have found to be very comfortable for long rides of 125-200 miles. I had heard great things about these and while they were on sale I jumped on it and got a pair. Sadly, one ride out in them and I knew they wouldn't work. after 75 miles I hated the pad and had the sore butt to prove it. It was a good . try, but I went back and got another pair of Velocissimo. I am 5'11" 178 and usually wear a medium. I sized up to a large on these and they fit great. Just a bad pad.

First of all, super comfortable fabric. Feels like a second - better - skin. Compelled to write a review because I crashed wearing these. Went down hard on my left side. I knew before I even got up the skin on my hip was GONE. Not so much as a thread pull on the fabric. Seriously. NO DAMAGE, Not much fun peeling them off after another 22 mls, but ...yeah, great pc of equipment.

I've worn these on three century rides, and they are the most comfortable bibs I own. If you're in the market for bibs give these a try. You won't be disappointed.

Great bibs

Caught the $149 sale and crossed my fingers on fit. I selected the XL based on tech specs and reviews. My sorpasso cold weather bibs are a L but are form versus race fit. Same chamois in both. The suspenders are on the tight side with the aero bibs but tolerable. Rode 32 miles the day I got them and am happy with the new piece of kit. I’m 6’2” @ 200# with a +|-2#. Also these bibs are made in El Salvador. This is where I think the variations in fit happen. All of my cycling kit is from castelli. Manufactured in Romania, Morocco and El Salvador.

I was on the fence about bibs. Not anymore. These Look great & feel even better. One word of caution: Castelli’s run small. At 6’ and 195 lbs, XL is plenty snug. And it’s the suspenders where I notice it the most. My Castelli CX suits are XXL and I could’ve gone either way with the bibs.

This is my go to bib. It can take a beating also, I have fallen twice (cornering at low speed) and they have no visible wear or damage. They run a bit small, so size up. The length is perfect in my opinion, and once the gripper at the bottom of the leg is in place it is not moving. The Progetto X2 Air chamois is great. no complaints.

I like super euro tight fitting race kits. These fit the bill. The inseam is a little shorter and the fit is tight. Runs "small", but only if you like US sizing. If you do, size up one size and you will be happy, but the inseam may still be a little shorter than most Americans are used to. Great bibs though, high quality with a great chamois.

I have been a long time fan of Castelli ever since I tried there Kiss chamois back in the early 2000's. These new Aero Race shorts stay true to that quality and fit that I have come to expect. The new Progetto X2 chamois is awesome. The shorts fit snugly but very comfortable and I am glad I sized up. If you do the measurements and follow the chart you should be good to go. I will be purchasing another pair soon, to replace my worn out Kiss shorts.

are these back to normal fit; like pre 2016? I used to get 2 bibs per year, same ones every year. Then in 2016 they changed something, made them super tight with a weird fitting chamois. Returned them. 2017, same. I've worn the hell out of what I have, and havent found a good replacement bib from anyone else.

Beautifully made but because it is a little small (I ordered a medium and probably should have ordered a large-I am 5'7", weigh 170 with a 34 waist). The shorts are fine on my trail bike which has a wider seat, but my road bike which has a Fizit seat becomes uncomfortable after about 30 miles. When I order another, I will get a large. The quality of construction is well worth the price.

These bibs are super sweet. The fit is really nice, and the chamois is more comfortable than most. Pretty simple bibs, nothing too fancy, just super fast!

What is the inseam length on these?

These are great bibs, but I wish the inseam was an inch or so longer. I'm 6' with a 34 inseam, and the Medium is cut just a hair short for my liking. Still highly recommended, however.

Approximately 8 inches for size M, btw.

I typically wear the LG line but was in the market for bibs with higher quality chamois. The Progetto X2 chamois in these bibs is definitely a step up from the LG Airzone and and a little more forgiving than the LG 4Motion . I definitely feel the difference with a more comfortable ride over longer distances (50+ miles). I am 6' 1" 190 lbs and settled on the XL (I usually wear a L in the LG's). These still have good compression on my rather slender thighs but I wish the straps were a little longer and wider. But so far these are the best bibs I have used.
