I'm looking for the most comfortable bib shorts specially models that reduce pressure on sit bones.

I love Castelli Free Aero Race bibs, but YMMV.

After trying many, Assos is by far my favorite.

+1, I won't wear anything else now, they're great.

I've done 8+ hours in the saddle with zero issues, don't even use chamois cream.

+2.. though I understand the Castelli Endurance 2 bibs uses the same chamois and may sometimes be found for more reasonable prices.

Good point, it's the Progetto x2 pad you want. My winter tights have the same pad. I also like the wide leg grippers, I have big legs, so narrow grippers are uncomfortable.

The pad is the same, but the materials are not. The the front of the thighs on Endurance 2 bibs wears out far faster than on Free Aero Race bibs. I have both, and the Endurance bibs just don't last anywhere near as long.

Good to know; saves me the headache of wasted money or returns.

FWIW, another chamois/bib that I have had success with are the Sugoi RS Pro bibs.

It's a a very personal thing. In the past 40 yrs I've tried many of the options but Assos works for me.

So that would be ones with a nice thick pad, except that puts pressure on the soft tissue, so a thinner, firm pad.

They should fit tightly to prevent bunching and friction, but that is constricting so they should be loose for breathing and comfort.

The straps should fit closely so the crotch stays in place, but the straps should fit loose so they don't cut into the shoulders.

They should have a nice big pad for sitting up on the cruiser, but have a small one that doesn't get in the way when hammering in the drops.


I wouldn't listen to these guys, because they ride a lot and their sit bone areas toughened up long ago so it's hardly a factor for them.

Yeah, it's worth the extra $20-30 for the Free Aero Race bibs.

Pactimo 12hr Summit Stratos is my favorite so far but I have only had about 5 different bib shorts. These are expensive but they have big sales at least a couple of times a year when you can get them 35-50% off.
I also have some other less expensive Pactimo bibs I like. One interesting thing I found was that on my old bike with Sell Anatomic X2 saddle, the cheaper bibs were more comfortable. On my new bike with stock Specialized saddle, the Stratos are way better.

Assos --> especially their upper end (forget the model names)
La Passione --> these are half the price of the upper end of Assos and just as good, although only come in black

The higher end Castellis are supposed to be comparable but i havent tried those - most of my Castellis are the mid-range ones i use for my weekday / indoor rides (90' or less).

I've got 3 pairs of the Free Aero Race bibs, and 4 pairs of Assos. I like them all, but would give the edge to the Assos for comfort, mainly because of the straps.

I just received some Campagnolo Vanadio bibs...hoping they are comfortable. My first pair. Bought them from BOB Shop in the Germany at 6PM their time Wednesday and they arrived here Monday. Quicker than State side vendors.

This is SO PERSONAL. Like asking what is most comfortable saddle.

saddle shape is far more personal, but I understand what you are saying.

I will concede the point.

BTW my body does like Assos but not everyone does well with them.

How do you like these? Any experience with their jerseys, too? I love the look of some of their stuff, but I've also heard that they wear out relatively quickly.

While I understand that everybody's ass is different, it might be interesting to see if there's any more universal opinion as relates to hating/disliking any particular brands (might be more illustrative)?

Bibs are a VERY personal decision.

I wear Segoi RS Pro bibs

I hate dense and/or thick chamois. I seem to get along fine, otherwise.

Endura FS 260 sl ii are my favorites because the customization options give me exactly what I want, plus the bib straps don’t go over the nipple. Just got the Pearl Izumi interval and I have to say that they have upped their game—love the laser cut straps and the material is sooo soft. Pad is a bit thinner than the Endura and I haven’t done a full day in them as yet though.

Assos T.cento_s7 for me. Very comfortable overall. Their "kuKuPenthouse" makes a huge difference for comfort, so much that I'll probably never buy anymore any bibs without a similar "pouch". That being said, excessive amount of seat bone pressure IMHO is mostly an issue of bike fit and saddle choice, bibs may help to certain degree but they will not solve the fundamental problem.
