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.
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
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.
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.
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.
I use the shorts for my longest rides. Very comfortable 4+ hour rides. Only negative recently is that
Castelli is making their straps a little short. I have several versions of these shorts and it seems the straps
are getting shorter with each pair. I'm a tall rider so not a problem if you are average sized.
Most comfortable bibs I have ever worn. Great cushion, but it doesn't feel like a diaper. Tight fit, so it doesn't move while riding. I got a size medium and have a 32" waist.
