Essentially the same bib as the Equipe RS Bib Shorts S11, but with a few differences. The RS has bit more room up from than the R, but it's tolerable. The RS has a very thin seam running up the center of the codpiece, and the R does not, so it lays flat much easier despite having less room. On the underside, the front of the chamois of the RS has 24 holes which provide fantastic ventilation. The R does not have these, so it's a better bib overall for cooler rides.

The leg length and S11 compression is exactly the same, as is the strap design / bib attachment. On the underside of the leg openings on the side/back, the R uses a row of 4mm u-shaped grippers, while the RS uses four rows of smaller, 1cm coin-shaped grippers. Both work great and are of course a personal preference.

Other than that, the bibs are almost exactly the same - with the R being slightly less expensive.

This is mainly due to the RS utilizing a more technical, lighter, and breathable strap material than the R.

Can't go wrong with either one.

Unlike most other reviews here, I'd say these bib shorts might not be suitable for everyone. In my case, the thick padding can actually make things worse since it needs to be precisely positioned; otherwise, it creates uncomfortable pressure points underneath. While I've had a few great rides with them, most of the time they've caused discomfort. Many have mentioned no saddle soreness even during long rides, but for me, discomfort typically kicks in after about 5 miles. My bike fitting remained consistent across both good and bad experiences, so it seems my rare positive experiences occurred when I happened to position the padding correctly, while most of the time it was just slightly off.

I have been using this bib short just like the previous version, on road and gravel. The legs are long for protection with good compression and the grippers are wide and hold. The pockets are secure and large enough to hold my iPhone and easy to access while riding. The pockets are close to the thigh when empty and easy to stash wrappers while riding. I actually had to look if my phone was on my thigh because it was so comfortable. This short has everything I need for comfort and ride protection. The chamois is very comfortable and the shorts are abrasion resistant.

I am 6'4", 205 and initially wondered about the fit of these bibs; particularly would they be too short, particularly in straps. Ordered X Lrg/Long. I have to say they have exceeded my hopeful expectations - they fit great! The straps are a little tight, but nothing that I would consider an issue, and this certainly would not prevent me from purchasing another pair. The material and construction is excellent and the pad is superb. I was able to get the "long" length, with is perfect - kudos to Assos for offering this extended sizing.

Overall - despite the relatively high cost, I feel these are definitely worth it and would (will) purchase again. Ordering from BTD is a plus as well - great pricing and customer service.
