I have been wearing Cento bibs exclusively for several years now. The cento bibs have the most padding, 10 mm rather than 8, of any Assos model which I prefer. Also the straps on the Cento model are particularly wide and comfortable. The evo are a noticeable improvement over the s7. The front kudu pocket is a lycra type material rather than fabric, the padding is black and the straps even better than the s7, which themselves were excellent wide and comfortable. Note that the sizing is based on height and not weight or waist size. The bibs fit better if not bought larger than recommended, the padding will seat, position better. I'm 5'7 and medium is the recommend size for me and fits me better than large (which I also own). Although the s7 are still being sold and are a bit cheaper, I feel the evo are worth the additional cost. When Assos makes improvements, the improvements address technical issues and are not simply cosmetic marketing.
The old saying YOU GET WHAT YOU PAY FOR fits these bibs to a tee. I have been cycling for 12 years and have tried all the top brands out there. These are pricey but will never buy another brand. From the first ride i took to then wearing my pearl pro and Garneau there is no comparison. I now have 2 pairs of the cento evo and 2 pairs of the rsr9. Both are great but i like the cento best. They run a little small like a lro bib normally does.
These are very well made shorts that are super comfortable over a long day on the bike. I've done a few double centuries in these now and I'd have a hard time going back to anything else now that I know how comfortable bib shorts can be.
The kukuPenthouse is about the most ridiculous marketing term I've every heard, but, you know, it actually works. With my other shorts, I get pressure points and chafing around my privates on longer rides. With these shorts, I don't even notice the shorts.
Everything about them is well made and comfortable. Since they're my most expensive shorts, I generally save them for longer rides, but I think I've worn and washed them at least a few dozen times and they seem as good as new.
Now if Assos could figure out a way to make my legs feel the same after 150 miles as they feel when I start the ride, I'd be in seventh heaven.
