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 constituting 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 in 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.

The right feel

  • Size Bought: M

I purchased the Equipe S7 and the Cento S7 together and I am very impressed with both. As the Cento is a more race fit - more snug, with a slight heartier feel and very streamline fit to the body, the Equipe is slightly more relaxed and extremely comfortable for long days - given i can fit into a large in both but ride in mediums by choice because I prefer a snug fit. The Cento S7 is simply top quality. Another killer feature in all Assos is the fabric of the bib straps. All seamless and lay quite well, proving to be comfortable for hours on end. I feel these will last quite some time and I am very please with how they fit and feel.

Best Bib!

  • Familiarity: I've used it several times
  • Fit: True to size

I bought here in CC Giordana Forma Red, three different pairs, I thought it will be difficult to find better bib until I bought this bibs, really confortable, light for long rides and keep me dry in really hot conditions (Cancún, Playa del Carmen, Tulum......)

T.cento - Long ride happiness

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: Medium

I’ve been putting off upgrading to great bibs for a while but I knew it had to happen. I went for the best and these did not disappoint. Excellent materials and construction. The chamois is very comfortable. These fit my legs and body well. The front pouch is luxe.

Even though I have long legs, I was ok with the length hitting me just below mid-thigh. They stayed in place no problem.

I went on the smaller size of my M-L size range due to the T.cento being cut a little more comfortably. The medium is perfectly snug.

Two long rides in. Great bibs.

Chafing short shorts

  • Familiarity: I've put it through the wringer
  • Size Bought: XL

Came in a really fancy box.. which probably took $10 to produce. The chamois is thicker than any bib's I've owned, borderline comical butt pads. These bibs did not get a break in ride, first wear was the dk200. They fit true to size in sholders but the length of the shorts is shorter than normal. The jumbo butt pads didn't seem to help much and when I finished the ride the stitching that goes around the thigh is very coarse and chafed my legs bad. Will review again at 1k miles.

After less than 2.000km during 7 months , I got a big hole under the chamois. I always hand wash my shorts and take good care of them.

Awesome Bibs!

One of the CC staff recommended that I try these bibs. I asked for "the best, no matter the cost." The bibs came to my home very fast and I put them through their paces on a few very HOT rides. I immediately loved the feel of the fabric, the look, and the fit. The straps actually hug your torso in racing position. The chamois is bar none the best I have felt on my bottom. Sometimes you have to pay the bucks to get quality like this. I have tried all the other big name brands over the years, and these are keepers for sure. Make a great investment and BUY these bibs!

It is a sad day.

My 4 1/2 year old, 13,000+ mile T.cento bib shorts have finally given up the ghost. Well, not entirely. But the padded strip that protects the backside against the seam that joins the "wings" to the chamois has come unbound. These were my favorite bibs. They did Dirty Kanza and, when I got off the bike, my backside was the only part of me that didn't hurt. Nobody makes bibs better than these! But . . . there's a silver lining on this cloud. I bought the bibs in January 2014 for $399. Today, Competitive Cyclist has NEW ones listed for $299! Still expensive, but worth every penny!

Another great Assos Bib

  • Fit: True to size

Ive used Assos since 2003 and ive never been disappointed. In fact i still have a pair from then that i still use. The latest iteration are superb as well. I usually save this pair for my rides over 50 miles and they perform great. Not to tight, very comfortable. And the kukupenthouse is great, though my wife says they should have called it the “cockpit”.

Chamois not holding up

  • Familiarity: I've put it through the wringer
  • Size Bought: XL

These are my favorite bib shorts but I'm rather disappointed that the material covering the chamois is wearing out prematurely. Small holes are appearing in the fabric. I always hand wash all of my bib shorts and jerseys with Assos Active Wear Cleanser. All my other Assos shorts are holding up very well. But these are not going to last a full year.

Simply the best

  • Familiarity: I've put it through the wringer

It’s easy to assume that one product is pretty much the same as another but Assos is simply better. When you buy the product, there is a small booklet that explains some of the reasons why it’s better but anybody could write that kind of brochure. I find the comfort is well beyond any other bib shirts that I’ve ever worn. If I’m just going for a short ride, I use one of my others but anything that has me in the saddle for a period of time warrants Assos.

Best bibs I've ever worn. I honestly can't fault them from a materials, fit, or aesthetic standpoint. They're not cheap, but I would class bibs in the 'you don't wanna skimp here' category. Please let me know if you have any questions about sizing. You can reach me at

Absolutely the most comfortable bibs I have ever used. They really shortened the length of the inseam, hits about mid thigh. They look absolutely RIDICULOUS.

Agree. Comfortable, too short, and look ridiculous.

The rear terminal looks like missing sewing ,don’t be sad like I was,it’s intentional. Best fit, form and functionality I will be purchasing another pair to phase out my castelli and be a true Assos cyclist 🚵‍♀️

Worth every penny

Have 3 rides on these bibs all in the 60 plus mile range the shorts fit well and the chamois is the best yet.

I rarely write reviews but I had to this time. I have tried a lot of bib shorts and can say that most are pretty good. This bib short is by far the best. It's unreal how comfortable they are. Some would balk at the price. I say you get what you pay for.

Premium quality; premium price.

  • Familiarity: I've put it through the wringer
  • Fit: True to size

As a cyclist for nearly 30 years, I've worn clothing from a lot of different manufacturers, and while there is certainly some fantastic clothing out there at a fraction of the price of Assos, there is still nothing quite like Assos. They've been on the forefront of cycling apparel technology since riders started making the transition from wool shorts and jerseys to Lycra and other synthetics.

The T.Cento is positioned as Assos high-end "comfort" bibs, which means that they are a little heavier material than the Campionissimo (and thus will last longer), and also have a slightly more forgiving cut for the larger-sized of us.

And as long as they last under normal use, they are well worth every penny.

Update 8/23/2018 - still going strong!


    These are my everyday bibs and I couldn't be happier. I'm surprised to see some riders having issues with wear on them - I haven't seen any on my three pairs.
    These bibs do have a 10mm chamois with the kuKuPenthouse, which is one of the best things that has happened in cycling on the past 5 years;) Designed for long-endurance riding, so the compression is more relaxed than the Equipes, or the Campionissmos. The inseam is shorter as well, so those that care about that tan line, beware. As with all Assos gear, the fabrics used are super nice and the construction is top-notch. Please reach out to me if you have any questions on these or any other Assos piece.

    I’m having problems with all my bib shorts. The cuff at the bottom of my pants roll up after washing several times. Years ago the cuff had an elastic internal band to keep pant in place and keep cuff from rolling up externally. Do these bib shorts retain a flat cuff over many washings? I don’t mind paying top dollars but don’t want to have a problem that I have with Shimano, Castelli, etc.

    I have not had any issues with these rolling up. Happy to help get you in the right pair and size. Feel free to email or call me. / 801.204.4545

    Short shorts

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

    I've been a long-time user of Castelli, but felt like trying something different in the upper end. So last fall I bought a pair of Assos tk.Tiburu knickers, and an Assos long sleeve jersey, and love them both. So I figured I'd now get some bib shorts from Assos, and bought these. I really wanted to like them, and while they have some nice features, there's other things that leave me disappointed. I'm 5'10" and weigh 155lbs. Large is my correct size but the inseam is shorter than any other bib shorts I've worn (Castelli and Giordana). Also, the straps while high quality, feel heavy and too short and stiff, which I feel while riding. They should be something you never notice when riding. They use the same straps as the heavier weight, colder weather knickers, but should use a lighter weight more perforated strap IMO. Having said all this, overall the shorts are high quality and the chamois is comfortable. I've only worn them once, and will decide if I keep them or not.

    No competition for long rides

    I can't imagine doing a century or long ride without these. The chamois is thick and luxurious. My only complaint is that the inseam is short for my taste; I'm 5'11" and mostly legs. I prefer the length of my Giordana bibs, but the chamois is second to none.

    I agree, the length is a bit short for my taste. I'm barely 5'10" and I have these in L.

    Assos really needs to lengthen these bibs. It's the only issue I (and many others) have with them!

    Assos were disappointing....

    • Familiarity: I've used it several times
    • Fit: Runs small

    Wanted a premium pair of bib shorts, so I thought would buy the best. Wanted these to work but it wasn't in the cards. Pad was a little thin, they run small, with short inseams. I've worn the bibs for approx.. 8 - 12 45 mile rides and the padding seam busted. The material felt great but the padding left a little to desire. Overall quality was nice, but not $275.00 nice. I'm 6'3", 255lbs, will return these and try something else. somewhat disappointed due to Assos being a premium garment.
