Item # AAS000C


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.

  • Long-distance/endurance bibs from The Cycling Shorts Company
  • More accommodating fit than Assos' race-fit bib shorts
  • Gently compressive material laid-out in an inimitable pattern
  • Free-floating chamois moves with you rather than against you
  • The playfully christened kuKuPenthouse adds men-specific comfort
  • Since the brand was launched, Assos has enjoyed clandestine popularity throughout the peloton

  • Familiarity: I've put it through the wringer

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.

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.


    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 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.

    Assos were disappointing....

    These bibs fixed many problems I had been having. I typically do 30-70 mile rides with anywhere from 2-4K feet of climbing, for the longest time I've dealt with my business going numb. I've tried many different bib types spent quite a bit for a very precise bike fit from a very reputable fitter. But the biggest fix has been purchasing these bibs. It was hard ponying up this kind of cash but it was definitely worth it. With what I spent trying different bib brands out I probably could have bought 2 additional pairs.

    Didn't even get a chance to wear them

    • Familiarity: I returned this product before using it
    • Size Bought: XLG

    I had 2 day aired these bibs so that I can wear them when I ride this weekend. when I opened the box the first thing I saw is a giant rip in the seat area of them. Either they have been used or someone didn't take the time to check to make sure they were sending out a good product. I am extremely frustrated because not only had I paid extra to 2 day air, I have to pay to return the item.

    Assos T.Cento_S7 Bib

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

    I really wanted to like these bibs given what I paid for them, but had to send them back. I kept them up to the deadline, I kept thinking they must work better than they do. I swapped rides with my other shorts and bibs, but these bibs consistently caused pain. I think the chamois just stops too short, doesn't extend underneath far enough in the front, and these have the kuku penthouse which may have something to do with it. Or maybe the material bunches up, but I was standing up in these bibs before I hit 20 miles. And I bought them thinking they would be my long distance bibs.
    I am 6' 3", 205 lbs, very experienced rider. I got the XL, fit perfectly and were very comfortable until I got on the bike. Overall quality seemed very good, the chamois just did not work at all for me.

    not great

    • Fit: True to size

    I purchased for a 100 mile ride. After 33 miles bruising and intense pain. Not worth the money.

    Assos T.cento-S7 Bib SHORT

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

    Product may be good but problem is padding inside, it is not enough and stitches from padding rubs on your butt, in rides over 50 miles more damaging and causes bruises. I talked to competitive cyclist that i got it from and they did not honor their return policy because it was used. How do I know this expensive item is going to be good or not without putting it in actual use. Very disappointed it is not a cheap item in price to say forget it.

    Assos Bib

    • Familiarity: I've used it several times

    • Size Bought: Large

    I am 6' 1" and about 190 lbs. I ordered a large and I would say that I am on the border line between a large and X-Large. If you have big legs, I would go with the X-Large. I wear XXL in Castelli and Large in LG. I would say the sizing compares with LG.
    As for the bib itself, it is comfortable and I would say more so than my Castelli's. You will have to decide for yourself if the Assos are worth the extra money...

    My favorite bibs

    • Familiarity: I've put it through the wringer

    • Size Bought: XLG

    By far my favorite bibs, great for longer rides. The chamois just disappears and the penthouse is amazing. Very comfortable relaxed fit with slight compression. The front is nice and low for easy nature breaks. I find myself grabbing these even for my shorter rides. They are on the expensive side but worth every penny.

    Jason, for the XLG, what's your waste size. I'm about a 39", 5"7. Trying to figure out what size I need

    My favorite bibs

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

    I love these bibs! They feel like they disappear once I start riding. The pocket in the front is great. The front is also low to make for quick bathroom stops, but it is not too low that my belly shows. The compression is a little light but noticeable. I like the length, not short but not down to the knee - maybe 6-8" above my knees. Everything about these shorts is just right - not too much, not too little. I just can't get over the pocket...I wish every pair of bibs I have had it.

    I am 6'3, 200lbs, 34x34. I think the XL fits great

    Buy Sportful Total Comfort Instead

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

    I'm probably going to be in the minority but these shorts are not worth the money and do not live up to all the hype, to me anyway. The best thing about these shorts is the Kuku Penthouse, it does what they claim and other bibs could benefit with this addition. Otherwise the shorts did not do the job. First the chamois is too small and my sit bones were right on the edge of the chamois at the back end but in the center there was too much padding material on the sides and it hung down on the side of the saddle chafing my inner thighs. Also the transition from the padded area to the side is done with an additional strip of material sewn in which tends to chafe me. The worst part though is where the padding material is left out in the middle for perennial relief. This area pinch my soft tissue so badly I developed two hard peanut size saddle sores....not good. I cannot recommend these bibs.

    Worth the money. Straps are tight

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

    Note: I ride a lot (According to Strava, 14k miles in 2015, 10k and counting this year). Unlike many people I know, I wear shorts out rather than replace them when I crash or when they get moldy. I hope this lends some credibility to my review.

    I see one and two star reviews, but few people mention things like how far they ride and how fit they are. For the record, I'm fit, but I'm not especially fast or powerful and I never raced. I'm a middle-aged man in Lycra (a MAMIL -- if someone calls you this, it isn't a compliment), a bit scrawny, and I ride 50-80 miles at a time, four to five days a week, at 18-20mph on the flats. I've been riding for 35 years and wore Assos in the late 90s and early 2000s. I moved away from Assos around 2005 because no bike store within 30 miles carried it.

    I've ridden about 6000 miles on the Assos t.cento_s7 bib shorts (I'm on my second pair) and I'm basically reduced to a guy who owns one pair of summer bib shorts as all others pale in comparison.

    For me, the design is almost perfect. The straps are uncomfortably tight for me when I'm standing, but perfect when on the bike. I'm 5'8", 145 lbs, and I tried the mediums but they were too big in the middle, so the smalls are best for me.

    I wash these in a washing machine set to 'delicates' EVERY SINGLE TIME I wear them, in a wash bag. I'm surprised when people tell me they rinse off their shorts. Dirty shorts chafe. Period. FYI, I used Ecover wash (recently switched to Assos wash), and the shorts lasted about 5100 miles with no visible signs of wear until they finally gave out due to stress at the back of the right thigh, where the insert is sewn in.

    CON: It's fair to say I got my money's worth, given the high mileage, but clearly other 'cheaper' shorts will probably last longer. Having said that, didn't hesitate to order a new pair and I 'suffered' through a few rides on Rapha Classic shorts, which I would have said were perfect before I tried these.

    Highly recommended.

    Much Needed Relief

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: Medium

    I ride about 250 miles per week, and the limiting factor is usually seat pain. I experimented with numerous saddles but couldn't get past the 3 hour mark with the bibs I'd been using.

    I purchased the S7 Cento earlier today and took them for a 65 mile test ride when I got home. What a huge -- almost unbelievable -- difference these shorts made.

    Not only was I comfortable for the entire ride, but my lap times were even closer than usual. I was shocked when I realized how many minutes I'd been giving up to discomfort.

    The Penthouse is worth every penny. I've done a lot of rides trying to adjust the twig'n'berries, up-down-left-right, slathering on the Chamois Butt'r and keeping my fingers crossed, but often arrived home with some bits chafed bloody. (See photo - yes that's blood.)

    With these bibs, I feel like I can finally start putting in more miles without having to bail due to discomfort.

    I hope you have a similar experience.
