Six years in the making.

Assos' engineers worked with their Werksmannschaft factory team riders over the past six years to develop the all-new T.cento_s7 Bib Shorts. These stand as a testament to the Swiss brand's dedication to fit and function perfection, as they are the next generation of the proven FI.Mille. There are four new "mission-specific" models of bib shorts within Assos' technical-feature-laden _s7 lineup, with the T.cento _s7 aligning itself as the long distance, comfort-oriented option. The next level of Assos bib short innovation has officially arrived.

The main Assos-specific textile that makes up the paneling of the T.cento_s7 bib shorts is called Type.439. This fabric is used for the panels of the T.cento_s7, as it's incredibly comfortable and supportive. The material provides exceptional breathability, and it rapidly transfers moisture to its quick-drying outer surface. Additionally, this smooth fabric provides a moderately compressive hold, which, in turn, supports the muscle groups of the legs. As a result, these muscles are partially shielded from the fatigue-inducing effects of muscle oscillation that are derivative of road vibration. Countless prototypes tested by Assos' very own Werksmannschaft (the Assos factory team) riders proved to Assos engineers that this exclusive textile provides the ideal blend of compressive support and low weight. And like the other fabrics composing the rest of the _s7 bib shorts line, Type.439 was finished with an iceColor application, which is similar to Coldblack cooling technology in that it effectively reduces surface temperature in dark fabrics.

Assos engineered these bib shorts to provide a slightly asymmetrical compressive hold that stretches more around your body, rather than vertically. This tuned stretch works to firmly secure the shorts in place while down in the cycling position, feeling more dialed while sitting in the saddle than while standing upright. This feeling has long been known to Assos' devoted followers as the signature "click on" fit. This Advanced Ergonomic Pattern Design (AEPD) fit is ever-present with the _s7 line, and it's been further enhanced by its new Y7 bib strap design. While the _s5's straps were spot-on from a comfort perspective, this latest generation's straps have been moved outward in the front slightly for better support. For example, while positioned over the hoods or down in the drops, traditional bib straps generally create a gap away from the torso between the collarbone and upper hips. But by aligning the straps outward, more along the obliques, the straps hug the torso, mimicking the body's movements without any gap, regardless of on-the-bike positioning.

Now for the heart of the T.cento's technological dominance: the chamois. While we're always reluctant to use the phrase "game changer" in anything we describe, the research and development of the chamois might just warrant an exception. Assos is calling it the "kuKuPenthouse." Yes, that is the name, and we'll get to its meaning momentarily. But first, as with all of the _s7 collection, it wears the new amethyst color. According to Assos, this purple hue was chosen to pay homage to the clothing of Roman emperors, English monarchs, and members of Japanese aristocracy, as the historically-significant color highlights what it calls the "most technically advanced cycling shorts on Earth."

As the top-tier chamois within the _s7 line, the kuKuPenthouse received every one of the new technical innovations to emerge from Assos' extensive product testing. The engineers began with a 10mm-thick memoryFoam material. This was first introduced with the venerable _s2 FI.13, as its shock absorbing composition returns to its original position, "filling the gap," every time pedaling position is changed in the saddle through the shift of weight. The memoryFoam features multiple layers, with its superAir and waffle composition making up the first two. This perforated design works to increase breathability and to shed weight. Additionally, this dimpling, combined with the ultra-soft microfiber top sheet, effectively pulls moisture from within the layers below, which allows it to dry much quicker than the previous _s5 chamois. Once Assos got the chamois layup to their standards, the engineers began rethinking the way a traditional chamois is attached to the shorts. This led them to what they are calling the "goldenGate," which involves interrupting the stitching along both of the chamois' side panels, allowing a more "three-dimensional" freedom of movement in this sensitive, rotational area. Additionally, because the seams are eliminated, friction is minimized even further. But if that weren't enough, Assos went ahead and bonded its lightly-padded anatomical side flaps over this short-to-chamois junction, making the transition against your skin as smooth as possible.

And while the aforementioned is impressive, the true magic of this chamois is located at the front, as Assos removed the section of padding where a male cyclist's genitals would normally contact the chamois. In place of the padding is a soft, brushed microfiber layer, which creates a "nest," or cradle into which the genitals are comfortably supported, free of the chamois' foam padding. This is where the kuKuPenthouse name is derived, which is truly a first in chamois construction. Pressure is thus eliminated in this area, and ventilation is increased substantially compared to a traditional chamois. The overall chamois design was then finished off with a "rearTerminal" at the back — where the chamois' rear portion meets the lower back fabric panel — by fitting a smooth layer of durable and wicking microfiber in this high-stress moisture collection zone.

The Assos T.cento_s7 comes in a claimed weight of 185g. The leg panels were finished off with new low-volume, calibrated-stretch superFlat grippers to keep the cuffs securely in place, and small Assos logos accent the shorts throughout. They are available in seven sizes from X-Small to TIR and in the color Black Volkanga.

A must for the epic rides!

  • Familiarity: I've put it through the wringer

Rider info:
Cycling genre-longer distance road and mountain bike rider

The Assos T.cento_s7 bibs are the quintessential bib for the endurance or epic rider regardless of road or mountain.

While I'm not a elite athlete by any stretch of the imagination, I do like to push myself on longer rides and get the max elevation gain or distance that I can. Having a chance to use the top tier products from the best companies, it is a bold statement to say Assos is the best of them all.

The 10mm chamois(when used with the Assos chamois cream) makes any long distance effort in the saddle tolerable. Metric centuries seem like a walk in the park. 5+ hour rides in the mountains may burn out the quads, but the rear end is sitting on clouds. The quality of the product is second to none. Even the unwrapping of the box which contains the bibs is an experience every one should have at least once in their lives.

The urban myths are true. If you a longer distance rider, get the best your hard earned dollar can get. This is truly a bib for the discriminating rider.

If you have any other questions, feel free to ask me direct at

Hi Jaren, what size did you get? I'm 5'9" but weigh 173lbs with 33" waist. Any idea what size I'll be? I've been using L for my other Assos bibs but I'm thinking of sizing down.

Unanswered Question

How does the length of these compare to the old Fi.Mille_s5 longLeg? One of the things I loved about those was the longer length.

Worth the extra cash!

  • Familiarity: I've used it several times

Been looking for a pair of bibs I didn't have to continually adjust during my long rides....Found Them! Tried all kinds of bibs and couldn't find one that worked. These do the trick! Chamois is perfect. Never even noticed I had them on. Wear the same size as all my other Assos bibs. Going to get a back up pair soon!

Love at first ride, but wait for it...

  • Gender: Male
  • Familiarity: I've used it once or twice and have initial impressions

to see if they last. If they do I will be sold for good. Started training for 70.3 and IM and I have had all kinds of discomfort staying down in the aero position. I tried a new saddle and it helped, but adding these shorts to the equation it has made the remaining discomfort a non-issue. I was able to ride my longest ride of the last 2 years today and stayed comfortable down in the aero position for more than 95% of the ride.

Conflicting feelings

  • Familiarity: I've used it several times

This was my first Assos purchase, and I have some mixed feelings. They're quite expensive, of course, which made me reluctant.

The other negative is the care of "handwash with our detergent". I especially didn't like not knowing that until they artived. Saying nothing of the legitimacy of that care, that's enough of a pain to make me reluctant to actually wear them.

But... You put them on, get on the bike, and you forget they're there. They're that comfortable. I've actually only worn them a few times, and only for long rides (shortest was 70ish miles). No complaints about performance.

I don't know if I'd buy a second pair, but they do ride nice.

Update: Right after finishing writing that, I noticed that the price had dropped by $40. Two days later, there was a special for a free Uno_s7 jersey with the bibs, and I bought a second pair. And yes, I'm laughing at myself for that.

Responded on

I always machine wash my Assos bibs with no problems.

Poor fit

Purchase large, don't fit. Purchase extra large still don't fit. xxx large too tight. All other bib shorts from other manufacture fit me as large. Assos need to be up front and clear that their shorts are not made for normal size American cyclist. It's really nonsense. I just want a set of bibs that have great padding. Don't care about over expensive fabric!

not what they used to be

  • Gender: Male
  • Familiarity: I've used it several times

I have a pair of the older F.I.13 S5, and I love them. The new S7 is not the old S5. The S7 has a bulky and wide pad that is simply too much. The pad comes so far forward that the front of my upper thighs are chaffed after only 50 miles. The leg bands are large too, and not as comfortable as the older model. The quality seems the same. Overall, I think Assos needs to focus on what works and stop wasting money on incomprehensible marketing. These bibs are not worth the money given the design mistakes.

Responded on

Not worth the cost.... so I guess that their "incomprehensible marketing" worked!
The extra thick chamois seemed like a good idea but it is so thick that it rubs inside of thighs when sitting on saddle... this may ease with time and use but, more likely I will be retiring my pair early! The KuKuPalace, though, seems to be an improvement. It's a little disconcerting at first but is comfy, ending a problem that I experience with chafing and other chamoise folding, annoying and painfully grabbing hair and pinching tender bits..... so they are good, not great.

I hate to justify 368 dollars....

  • Familiarity: I've put it through the wringer

BUT.... Out of all the bibs I have bought, used, questioned, etc, these work for me... I'm not a Garmin/Sharp rider or a BMC groupie... I'm fat, i just started riding and logged 3500 miles my first year.. my first double century was in these and they absolutely rocked.... no chafing, no complaints.... Again, i hate to say that a 350+ bib did it because i don't think i will ever be able to justify another pair of these to the Mrs.(even if they cured cancer and i had the type), but that being said, long mileage, they work; humid conditions (and i'm from Florida so i know humid) the Kuku penthouse works, these are the best fu@*ing bibs i own and i tried everything from LG to Castelli and i own several iterations of Assos.... Gotta try them if you're looking for luxury and can justify the price... (Archer's Oscelot Babou is probably still not included...;)

i love assos, but . . .

  • Familiarity: I've put it through the wringer

ok, so i literally have 10 pairs of assos bibs in my drawer. pretty sure my wife has no idea how much these things cost, because if she did, there might be a discussion. in any event, the cento was the first of the s7 line i purchased. at first, i liked it. it felt good; the penthouse was comfortable, etc. at that point, i was riding for a couple hours. then i started training for longer rides/races. i was riding for 5 hours plus. about the same time, i bought a couple pair of the campionissimo bibs. i continued to rotate the new bibs (most of my assos is the s5 line), and when i got to the cento for a long ride, i was always irritated down there. this never happened with the old s5 bibs unless i was wearing my old xlg sized bibs. for better or worse, all this long distance caused me to lose some pounds. anyway, i put the old xlgs aside but always preferred the s7 line, which was all straight xl. but they don't fit that way. the centos fit like a larger size. there's too much fabric between the legs; it bunches up and causes irritation. it's a problem and a bummer . . .

also, someone asked if there is a bib replacement program. i crashed in a pair of s5 bibs last year. tore up the bibs pretty good. i sent them to assos and they sent me a new pair. now that's customer service. that's why i love assos, but i can't say i love the cento bibs.

Assos and my body do not mix

  • Familiarity: I've put it through the wringer

I recently upgraded my cycling gear for the first some in 10 years! I'm on the bike again like I was in college logging 250 to 320 miles per week. When it came to bibs, I decided to go all out with these.

The bibs are flawlessly constructed. Seamless panels, excellent leg grip, great seams...for construction quality there is no comparison.

General Fit:
I'm 5'9 weighing 148 to 154 depending on the day. My height is more in my torso than my legs. My waist size is 29 to 31 depending on brand. My jacket size is 38R. so according to Assos I should be a medium. So I order a medium and a small just in case. The mediums were too loose. The smalls seemed to be just right. The bib straps are just right with the smalls where as the mediums felt like they might slide down my arm over the course of a long ride. So I kept the smalls.

Fit on the Bike:
Everything seemed to be perfect with these bibs until I actually wore them on some long rides. I developed extremely painful saddle sores / brush burns right in the crease of my leg exactly where the inner chamois-pad ended. At first I chalked this up to my old saddle (specialized toupe). So I replaced it with a new toupe. I started to use chamois cream on my body and on the chamois. I completed a professional 3-D bike fitting. Nothing helped. The burns and sores continued. every time in exactly the same place where the bib padding ended inside the microfiber. I've finally come to the conclusion that while these bibs are extremely well made and clearly well designed, they are not appropriate for me or my body type.

Fantastic construction. Excellent materials. Extremely comfortable off the bike. Extremely painful and irritating on the bike especially on long rides (75 to 150 mile).

I wish there was a way to test drive products like this so as not to waste money on the promise of a great fit.

Is there any sort of crash warranty?

It's true - it works

  • Familiarity: I've put it through the wringer

Bought these in preparation for a cycling trip (~8 days, ~700 miles). The shorts are incredible. The first couple of times I was not completely sold as I've generally worn relatively thin pads before and the chamois felt awkward. However, as the trip progressed, the extra thickness on the Cento were well worth the expense. The penthouse for the kuku is awesome - hard to describe in words without risking having my comment removed by the profanity filter. For long days on the saddle, these are my go-to bibs. In fact, I would use them everyday but I'm treating them like gold. I am 5'10" or 5'11" in a good day and weight around 175lbs. Bought a size Large and fits well; however, I have the nagging feeling a size M may work just as well if not better.

5 5

Now what do I do with all my other bib?

  • Familiarity: I've put it through the wringer

As others have said the kuku penthouse makes all the difference in terms of comfort. This is my second pair of Assos bibs and I only wear the other brands when these are in the wash. As the other reviewer mentioned unless you are doing 50-60 miles and up I would stick with the other models. You get what you pay for with Assos and for those who scoff at the price, its only because they have not worn them. My only regret is that I did not get the Campionissimo instead, they are more money but unless almost all of your riding is 50 plus miles the padding is more than you might need. I am now saving up for them....

5 5

Most effective bib for distance.

I am normally a Capo fan. For shorter rides, i.e. under 40 miles I have been very happy with capo, but between 60-100 miles I was looking for better support and less pain. The Kuku Penthouse is a ridiculous name and an awesome idea that works well in practice. The biggest improvement though is the golden gate concept which really is amazing. Once the chamois is in place it literally stays there the rest of your ride. No more shifting the legs trying to adjust it back into place. My only complaint vs. my Capo's is the chamois has a very narrow sweet spot, but as long as you center it properly it works great. Otherwise the fit and finish is fantastic, although my capo's are very nice too. I'm not sure these benefits justify the premium price tag but for me they are my new distance bib of choice.

5 5

Like a glove

I got these today and was skeptical about the improvements over previous bibs. After trying them on and taking them for a short ride today found that they put a smile on my face. No doubt the pad is thicker but not intrusive. the areas that are usually sore in the beginning of my rides were not noticeable . I can't wait to take them out for a long ride for the final evaluation. I think these will be my choice for the dirty kanza and the bumps ahead .

Great shorts, but ....

  • Familiarity: I've put it through the wringer

These bibs are very expensive to say the least. Then again, your contact point with the bike can make or break a ride, so the money may be well spent. I wore these for 10 hours on a 300K brevet the day after I got them and was very impressed. I'm 6' and 163 lbs --- the size large fit well.

One note of caution: the pad is VERY thick. It's extremely comfortable, but If you are sensitive to saddle height, you may want to be careful. I lowered my seat height by 3-4mm to account for this pad thickness. It seems like a drag to have to do this every time I put on these bibs. Most of my other bibs (Castelli, DeMarchi, Capo) have substantially thinner pads and are much more in-line with each other. The Assos pad is a real outlier for thickness.

I also own one of the original Fl.13 bibs (which do last a long time if you take care of them), and it has always pulled a bit in the front of the crotch, even in the cycling position. These bibs do the same, and I find myself numb part of the time. It's not a deal-breaker but worth mentioning.

Will these work on a tri bike?

Expensive, but worth every penny...

  • Familiarity: I've used it once or twice and have initial impressions

I'll just say right off the bat, I never thought in my wildest cycling dreams I'd be dropping over $350 on a pair of bibs. I've worn Pearl Izumi Pros and Castelli Endurance bibs for the past six years and been content with them but there were always small gripes about them. Irritating seams on the bib straps, not enough room for my junk, legs too tight, bulky seams, etc. Well, recently I was going to purchase two pairs of the Castelli bibs (which have been my "go-to" bibs for about two years) but came upon the insane realization that I was finally in the position (finance-wise) to try out a pair of (nearly) top of the line Assos bibs. I was very hesitant to say the least. But when I really considered how much cash I'd spent on my helmet, eyewear, jerseys, and shoes, it seemed like a no-brainer that I shouldn't spare any expense when it came to arguably the most critical aspect of my kit.

To cut to the chase, after my first ride, I'm sold. These are, hands-down, the most comfortable bib shorts I have ever worn. In fact, I'm still wearing them now (yes, sweat is soaking into my chair). The chamois is insanely comfortable and the nifty little "treasure pouch" is a god-send for someone who has always felt cycling shorts were too constricting up front. If you're on the fence about getting these shorts, don't wait, order them immediately.

Can someone help with sizing for bibs?...

Can someone help with sizing for bibs? Both the Assos site and Competitive Cyclist base it on height. Is that how most people go with? I'm between 5'8"-5'9" but recently just went from 200 lbs to 175 lbs (waist size reduced from 38 to 34). My thighs are still fairly big, though.

Recommendations greatly appreciated. I'm not sure if I should go for Medium per the recommendations or Large.

Best Answer Responded on

Hi Gino. Our #s are close. Based on the info you have provided, I think the size L would fit you best. My advice? Try the L. If for any reason you don't -love- the fit, return them for a size M. Good luck.

Responded on

Thanks! I tried both and the Medium came out a better fit overall. It provides more compression but does stretch to accommodate my body size.

inseam length

  • Familiarity: I've used it several times

To clarify, regular length is 10 inches according to Assos. Long's are 4 cm longer. These are equivalent to the Mille regulars.

Responded on

There seems to be some confusion on this issue because the old Mille_s5 model came in two lengths. My observations:

1. The new T.Cento_s7's do NOT come in two leg lengths like the old Mille_s5 model did.
2. The new T.Cento_s7's are of normal/typical length (the same as bib shorts from Castelli, Capo, Pearl Izumi, etc.) I own a pair in size L (I'm 5'10"). They completely cover my quadriceps. They extend down to within 1-2" of the top of my patella when standing (within 2-3" when properly positioned on my road bike). T.Cento_s7's do not run short in the leg in any way.
