Pro Rider Approved — Castelli Free Aero Race 4 Bibs

The fourth iteration of the Castelli Free Aero Race bibs receive major upgrades for increased comfort, fit and durability.

The Castelli Men's Free Aero Race 4 Bibshort features a new leg gripper design with vertical silicone stripes to keep it in place without restricting stretch.

The seams have been updated to improve the fit and make this bibshort look even better on you, the rider. The bib straps have been re-engineered with new fabrics and construction to enhance airflow, durability, and smoothness against the body.

Impressively Soft and Seamless.

The revised Free 4 Aero Race Bibshort also receives the updated Progetto X2 Air seamless seat pad featuring the softest surface fabric you've ever felt in a seat pad.

You'll be glad Castelli ignored the old saying, If it ain't broke, don't fix it, because the Free Aero Race 4 offers pro status upgrades.

Features:

  • Vortex dimpled fabric on legs.
  • Forza fabric on inner legs with 38% Lycra® content.
  • Cooling stripe mesh engineered minimalist bib.
  • Giro4 leg gripper elastic for better grip distributed over larger area.
  • Supportive Doppio V construction in front.
  • Flat-lock stitching.

Great race bibshort and surprisingly comfortable

This bibshort is a great addition to my cycling clothing, because it fits great, is comfortable, doesn't move around in the legs, and is fairly minimalist when it comes to the straps. The seat pad is comfortable even at the 50 mile point, and I've ridden in some fairly hot weather without any sense that they're too hot. The only downside is that they're a bit pricey, but if you can catch them when Castelli is running a sale, they're definitely worth it.

Most comfortable functional bibs I've ever owned.

I ride about 200 miles a week in pancake flat Florida and these bibs have been the most comfortable shorts I've ever worn. Very pricy but in my opinion they are worth it. They wash and wear well and have held up for a few months now. I do not put them in the dryer and I think that gives them a longer life. The leg grippers are the best I've experienced functional and comfortable. These shorts are also very stylish and good looking. I now have a total of 5 pairs for each matching Jersey.

sublime

These bibs fit me so well I feel like they make me a better cyclist. They certainly help me cycle greater distances in comfort. They cost a lot, but the quality does not disappoint. Your lower regions deserve the best shorts you can get, so be good to yourself and don't cheap out! Fit is a personal thing, but the pad shape, texture, and overall construction are perfect for me. A word on sizing. I'm 5'9", 152lbs. I tried to go with a medium, but the bibs were too short for my torso. The shorts were pretty tight too, but I think they would have broken in. I exchanged for a large, and haven't regretted it.

Love them, they run small

Great bib, so comfortable! I normally wear medium and had to return for a large. The large is even slightly small, but I like tighter vs baggier, so I'm super happy. I just ordered a second pair.

Improved Pad and More Breathable

I have been using Castelli bibs (Body Paint 12 and Free Aero) for 10 years. I wear the large size (5'8, 150 lbs, 32 waist). The new Aero Race 4 bib-short shows Castelli's dedication to continually improve their shorts. The pad feels more substantial and comfortable when on the bike. The shell materials just fit great and feel more breathable. The grippers are vastly improved with excellent hold (vertical series of tacky stripes). The stitching on the seams and attachment point on the shoulder straps are improved- no frayed threads. I wash them in a mesh bag using detergent with no fabric softeners and dry on a towel warmer. After 20 rides all good- even the Castelli logo shows no flaking. The blue and the grey colors are subtly different than the standard black and compliment many of my team jerseys. I prefer these colors over the black. Highly recommend. JT

Comfortable to wear & comfortable on the bike!!

First time with the Progretto X2 seat pad - love it. Went with the compression version of these bibs & they are more work to get on, but after 50 miles of pedaling you can tell a difference.

Wonderful bibs!

They are soo good! I've had a hesitancy ordering Castelli clothing online because everyone always gripes about the sizing. The first pair I bought I did size up. To be clear they still fit and I thought everyone was right but since then I've ordered a couple more bibs in my normal size medium. I'm here to say that you should order your normal size if you feel you have a slimmish build. They are snug. It takes an extra second to pull them into place while getting them on but that is how they're designed to be. The right size feels a million times better once your into a bike ride. The pad is wonderful and probably my favorite I've come across in my cycling life. For reference I'm 5'10" and 160lbs.

The Comfort and fit of these bib shorts make me feel like a stronger rider.

These are my third pair of Castelli bib shorts but my first set of Free Aero. They were an upgrade for me but I bought them on sale at a great price. I'm 5'7" at 150 pounds. Like my previous two pairs of Castelli bibs I went with the mediums. Yes, like all Castelli bibs they are really tight when I first put them on but soon after the first ride, they seem to conform to my body. Most of my rides are in the 30 to 50 mile range and the comfort of the Free Aero bibs is really great. The combination of comfort and compression kind of makes me feel like a better sand happier rider.

Nice fit, nice pad

The new pad is very nice, and I like it better than the previous Castelli pads. The fit up front is much better too. Straps are comfortable and work well. I'm 5'7 132 lb and have worn medium Castelli bibs in the past but this one is a small and fits perfectly. Snug, but that's my preference.

Great fit and performance but poor stitching

I am a fan of Castelli bibs. The fit and compression on these bibs are perfect. I am 5'9' 160lbs and ordered a medium. The reason for not giving the bibs five stars is due to the fact that the stitching was coming out before I wore them. I only realized it about two months after buying them because I ordered in the winter when they were on sale and did not get them out to wear until the spring. Thankfully they are double stitched so they are no serious issues.
