It's been a few yrs since I've had to buy bibs but they were Mille GT in a size Large. From Competitive Cyclist.

I have a pair of these bought a year ago from Wiggle. Only bought them because they were very much on sale for $85 so thought this was a shot at trying Assos. I like them.

I got my Cento Evo order in this evening. I was able to try on the Mille locally and even the XL was pretty tight in my stomach. The large was pretty ridiculously too small on me. I'm dropping weight, but who knows how long it might be before I drop enough to make a big difference with a cut like the Mille.

I knew the Cento was supposed to be cut a little looser in the stomach so I ordered the XL anyway. I'm a little surprised by just how much looser they are cut in the stomach vs the Mille that I just tried on. I'm not sure I could comfortably fit in a large in the Cento, but the cut in the front is actually a bit loose. If I had to choose I would go with more comfortably loose than too tight, but it does make me wonder how much weight I will drop before they may seem ridiculously too loose in the front.

I think I may keep them though. If I do happen to manage to drop a significant enough amount of weight that they just no longer fit then I may deserve another pair of Assos and maybe I'll try those Mille again at that point and see if the cut of them is more favorable.

Edit: I did just retry these on with a direct comparison to how my Pearl Izumi bibs fit that I'm more accustomed to. I had one pair of PI in XL and one in large and I'm starting to fit back into the large again with those now that I've dropped some weight. I have literally never paid a bit of attention to this before now. The Pearl Izumi (Elite Pursuit - neither are the Pro line) - have a cut that goes all the way up to my belly button, but most of that upper section is part of the bib strap material that is just a mesh type of fabric. There's just a strip of more constrictive lyrca type material that goes up to the belly button that provides coverage for the stomach without being overly constrictive, but keeps things snug all the way to the top. The mesh is very forgiving.

These Assos Cento and the Mille are cut differently in that regard. They both come up short of the belly button by an inch or so and there is no mesh in the mix. It's all lycra. While standing upright the Cento seems a bit loose, but I notice that if I go down into more of a riding position that my stomach is going to hang down just enough that they are no longer loose fitting. My guess is that must be the goal of the design. To be as nonrestrictive as possible in the riding position for longer days of riding.

Like a leather motorcycle jacket - it doesn't look exactly right while standing upright because the cut is designed for a riding position.

They do feel otherwise like they are a great fit compared to the cut of the Mille which is obviously made for guys who are already very slim. According to a BMI chart for my height I should weigh about 153lbs tops, but I've never come close to that even when I was in high school. I might have been 160lbs at my peak condition. I'm about 181lbs currently. If I get down to 153lbs I will be glad to put these Assos on Ebay or put them in the closet in case I ever do need a larger size to get my weight back down.

I'm pretty anxious to try these on a 100 mile day ride. I did my first full century since 2016 last week. It was a brutal and miserably hot experience . Looking forward to it hopefully getting a little easier again.

Hello,
Could someone tell me the dimensions of the st.100 CENTO bib shorts XL ? I'm interested in an offer, I usually wear XL bibs, but these shorts are different in size than others...

I've edited my previous post...too big picture ?

Worked now. Not sure.

Have a pair that are at least 4 years old, with many miles in them. Just did a century last week and they felt finey on the hinie.

Bought my first pair of Assos last month. They're the entry pair, Reform P3. ended up having to exchange them to a larger size. They're pretty comfortable, probably the most comfortable straps on a pair of bibs. I find them still a bit snug/tight right along the top of the thigh. Not terrible but just enough I notice it. So far my favorite bibs are from Attacus

Since no one so far seems to have these shorts, I’ll say I’m XL in most Assos. 6’2 (190cm) 42” chest 32” waist (the shorts could easily handle wider) with long and probably mid diameter quads.

I will chime in on the design, build quality and comfort/performance of nearly all Assos products. If you shop the sales that are often shown by Assos, it helps to pay 30% less, but of course not all of their product line is at discount. As we used to say regarding tools, buy the best and cry once. I have never been disappointed with anything from Assos - shorts, jerseys, base layers, gloves, hats, sun glasses, and recently their MET Assos helmet. And the stuff lasts forever, mostly.

I also have a number of Rapha products, cargo bib tights and shorts and yes, the external pockets are very nice. I have not had the same good experience with all of their product line, whereas I have with Assos. In particular, on three different Rapha jackets and jerseys, the zipper has failed (it is a YKK). Often it as after the 12 month warranty period and Rapha would not repair or replace the item, but offered me a discount on a new replacement, but only after I complained to a supervisor. For a wind front jacket that was now reduced in price to about 170 Euro, I felt burned. I bought it last year and used it for part of the winter, then pulled it out this year for winter and it was perhaps 14 months after initial purchase (directly from Rapha), so outside of their 12 month window.

For what it is worth, I have returned stuff to Pearl Izumi for warranty repair, sometimes when the jersey or jacket or other is a number of years old (5 or more in some instances). No questions from them; they either repaired the item or replaced it.

Castelli are also very good with customer support.

My worst experience has been with Gore Wear cycling products. I had two pair of gloves fail with stitching coming undone, the palms wearing off, etc. I could not return the product to the shop where I purchased it because they were no longer in business. After months of writing to Gore, they told me, sorry, not our problem since you bought them from a retailer. I will never own another Gore product regardless of sale prices that I may see on 2nd party web pages, such as Bike24. Just send the customer the same or similar product and say 'sorry that your experience was not good with our product(s), try these and we hope you are satisfied.' Again this builds brand loyalty and cost the company very little and in return they will get free advertising and I would always promote them to others in the cycling community.

Customer support is where it is at, and when a company does not support their consumers, particularly with premium priced products from Rapha or Gore, they loose consumer loyalty and hell, customer support even if the company or vendor feel that the customer are wrong, is the best form of advertising that a company can make. Hence I will buy products from other companies who support us - the consumer - and never Gore, and seldom Rapha. Yea, I like Rapha stuff and it is stylish, but it is pricey and their return policy has burned me on three occasions. ok, off my soap box...

I'm just going to add the fit will be always somewhat personal. We're all built slightly different, the bikes we ride are different, the saddle is different, position we find comfort in is different.
Too many variables to have a perfect piece of bibs fit everyone just right. However, with Assos bibs I have not been unhappy yet. I have the Equipe R, RS, RSR and Mille GTS C2 all
in same size L and all fit great. These are pricey no question, but you can get decent deal if you're patient enough. I tried other ones from other brands and my conclusion thus far
is Assos fit me best. I never wanted to spend this much on bibs and tried some budget options, I really like Rivelo Honister, I think for the price these were best ones out there and I could
easily skip any other budget or mid-tier bibs for these. I could do century ride in them and was fine. However, once you put Assos on, well, the comfort is just at another level.

To each their own, I guess. About 5 years ago, after reading and hearing about how much people love Assos bibs, I shelled out $260 for a pair of EQUIPE RS Bibs. Meh. They chafe. The chamois isn't much better than other bibs. Maybe I bought the wrong design or model, I don't know. Or probably it's just me.

I hardly wear them. Instead I wear The Black Bibs which cost less than half as much, and I love them.

So I'm an outlier, it seems.

Wow. Never had chafing from about 6 pairs at all different price levels. I guess we’re all different

Just to clarify, it's the shoulder straps that chafe me. They just don't fit me right. Yes, we are all different - Nice for everybody else that they love them so.

Ah I usually wear a mesh base layer under the straps.

I actually think the straps are the best part about them haha
