These are great bibs. I wore specialized SL bibs for many years before I decided to try these, and I wish I hadnï¿½t waited that long. Iï¿½ve been using three pair for three months and they could pass for new after many wearings and washings. And most importantly, they are very very comfortable!
These are typical of high quality Assos products; well made and seems like they will last for quite a while. I bought these as a marginally lower cost option to compliment a pair of GTS summer bibs (which are fantastic by the way), as they seemed to be quite similar in construction and fit. I tried them on when they arrived and all seemed well. However once I rode in them the first time, I felt as I had made a huge mistake. My issue is with the leg grippers/bottom of the shorts, which for some reason start to rub on the backs of both knees after about 30 mins of riding. Iï¿½ve tried adjusting where the shorts sit by pulling up higher or shifting myself around but nothing Iï¿½ve done resolves the problem. Iï¿½ve washed many times at the suggestion of customer support and that has not helped either. Iï¿½ve resolved to only wearing for shorter rides or just accepting that theyï¿½re going to annoy the crap out of me if I do ride much more than an hour.
This is a very specific issue, so take it with a grain of salt. You may fare better, but honestly Iï¿½d just go with the GTS bibs if considering both.
Though $30 more than previous years Mille bibs, these are definitely better built. The X-Frame straps are cooler on warm rides, the chamois is a tad wider which helped me, the leg grippers are much better than the old school silicone bands, and lastly the junk cradle is a bit better. I have done several 4-6hr rides in these and really just forgot about them where in the past I would have to readjust the chamois to get the seams off my sit bone. I use these for endurance MTB and I have used Pearl Izumi, Giordana, Jakroo, Bioracer bibs as a comparison.
Some changes to the straps I was not sure of. After a few rides, don't notice a difference between these a few older pairs of S5 Mille. They make great stuff and the best sign is you don't think about the bibs when you are riding, you just ride. Would buy again, and these guys get things out quick and keep you informed.
From day one I have never thought about them. Zero hot spots. I'm riding 6 days a week on a trainer or outside. Max trainer sessions of 4 hours. I do use shammy cream. Can't speak for the other models but these took a few weeks for my tummy to get used to. There was a little chaffing from the upper seam across the waistline. All good now though! Bought size medium. 5' 10'" 160#
