A piece of Italian history.

The story of the Cento1 is synonymous with the story of Wilier. The Cento1 reinvented the road bike, and reaffirmed Wilier's role in the Italian dominance of the peloton. Now, the Wilier Cento1 SR Road Bike Frame is your chance for a sample of modern history. Fully loaded with technological innovation, superior ride quality, and a blisteringly fast geometry, the Cento1 SR is the only legitimate choice for anyone looking for the best that Italy has to offer.

Before the SR, little had been changed on the Cento1 (Chen-toe-uno) since Alessandro Ballan won the 2008 World Championships on his, and that's because Wilier got it right the first time. In fact, before the SR, the Cento1 was was widely consider to be among the most balanced framesets in the world. The reason was simple, the tight-wheel base geometry was coupled with a comfortable, tapered head tube. And this head tube's height acted as the stabilizer to an otherwise over-excited frame geometry. In other words, this juxtaposition creates a bike that remains comfortable over the long haul, but drops the hammer in the quick moments of an attack. Much of this remains true today with the SR, however, Wilier has added doses from its other top-offerings in order to make it the most balanced frame in the contemporary Wilier lineup. Now, elements from the Zero.7 and Twin Blade have been incorporated, creating a new breed of bicycle that places an equal focus on aerodynamics, comfort, and power delivery.

Along these lines, the Cento1 SR benefits from one of the most effective power delivery systems on the market -- the combination of oversized, asymmetric chainstays and the Wilier-developed BB386EVO. Don't get aggravated at the thought of another 'new' bottom bracket design -- the proprietary design is compatible with all leading cranksets. Developed in cooperation with FSA, the BB386EVO is a competitor-dwarfing 86.5mm wide and has a diameter of 46mm. Wilier estimates that the new bottom bracket increases rigidity by 30%, and reduces power dispersion to almost zero. Additionally, this shell's width provides Wilier with the ability to widen the seat and down tube diameters by around 20mm. And as simple logic tells us, this drastically increases rigidity, while also promoting an efficient power transfer to the rear triangle. But, this also permits Wilier to decrease the tube's wall thickness, further shedding grams. You'll also find that the BB386 EVO was developed to use press fit bottom bracket cups, eliminating the need for alloy inserts in the shell. Of course, this also shaves a good deal of unnecessary weight. Altogether, Wilier credits BB386 EVO with increasing overall torsional rigidity by 133% and rear triangle stiffness by around 115%.

Now, you'll still find that many of the Cento1's key elements remain on the SR. In fact, Wilier found that crucial details like an integrated seat mast and the material flow over the frame were too vital to disregard. In terms of the latter, you'll notice the top tube and seatstays of the frame are molded from one continuous piece of carbon fiber that flows seamlessly into the top tube. This design, along with the seat mast, createa rigid rear triangle that delivers direct power transfer with minimal energy dispersion. Additionally, it creates a highly predictable sense of stability on high-velocity descents.

To ensure rigidity and the confident level of handling, the Cento1 SR has been constructed from a 60t Mitsubishi high-modulus carbon fiber. The 'T' in 60t refers to ton, as in it can withstand 60 tons of pressure per square millimeter. Wilier used strong carbon fiber, because the stronger the carbon, the less is needed. Thus, Wilier was able to strike the perfect balance between strength and weight.

Other new differentiators for the SR include a stiff, multifunctional 3D derailleur hanger, a 3D integrated cable routing plate under the bottom bracket shell, and an integrated adjuster plate for your internal cable routing. Most importantly, however, is the SR's integrated fork. Easily the SR's most distinguishing feature, the down tube is angled upwards, while the top tube accommodates the head tube's downward angle in approach to the new fork. The ideology behind this can be explained simply. Traditionally, the aforementioned juncture shared a geometry with that of a triangle, while the new design resembles that of a square. And simple logic tells us that the expanded surface area of a square is stiffer than the poignant angle of a triangle. This technology has been proven with the Twin Blade, and it greatly reduces the SR's aerodynamic footprint.

The Wilier Cento1 SR Road Bike Frame is available in the colors Matte Black and Red and in six sizes from X-Small to XX-Large.

  • 60T carbon fiber

Among the Best of the Best

  • Familiarity: I've put it through the wringer

I have owned a lot of the most revered bikes in the world over the past 5 years, and have spared no expense to do so. Never did I think that I would ever find a bike that I love as much as my Parlee; enter the Cento1 SR.

Not only providing one of the stiffest platforms I have ever ridden, the handling is confident and accurate without being overly fast; and for a frame that is this efficient, the weight is incredible!

The comfort exceeds that of any other race bike I have ever ridden or owned; it is truly impressive.

In addition to the being a spectacular ride, there aren't any strange component proclivities that prevent use of any common parts. The one exception to this is the bottom bracket; though the only crank standard eliminated is BB30; all others work perfectly. The stiffness that the BB386 Evo bottom bracket shell provides is well worth the small restriction on crank selection.

This is easily one of, if not the best bike I have ever ridden or owned.

Among the Best of the Best

.....most awesome....

  • Familiarity: I've used it several times

Not quite sure how to do this as I usually don’t do reviews, however each time I ride the SR1 I feel the massive urge to share. Started out for my road bike needs with a super six years back, then bought a pina paris & now the SR1 & to sum it up right upfront - I arrived, I so did. This bike is simply beyond amazing. Not sure where to start, as the SR1 does everything so much better than my previous ones, it’s amazingly stiff and yet so super comfortable & compliant without holding back/filtering out road information. As I am running this 386BB with ultra torque adapters I only can imagine how it would transfer power with a full blown 386 crank set. It’s super stable (not lame) on high speed descents, yet super agile when needed without being nervous. The most amazing thing which always makes me want to ride more is that this bike simply disappears under your butt & becomes one with you. You’re not riding a bike, the bike is becoming an extension of you moving on wheels. Many thanks to Wes Branham

, Brett & Mike at Competitive to make it happen & Wilier for a magic layup of 60 ton carbon. Riding the SR1 has been nothing but a revelation.

.....most awesome....

Hey Jo, since you had a pina paris, how are they compared in terms of comfort and stiffness?

Mike, sorry about the delay........not sure if it makes sense, however the SR1 is stiffer and more comfortable in my opinion, have to say though that i run it with Schwalbe one tubless in 25.......the pina had 23 with tubes, which was comfortable, but did not feel as it would transform pedal stroke into straight forward motion like the SR1.......i recently ran it with some 23 tubed on zipp 404 and that was very direct in terms of road feel, but still would not call it harsh.......dang, i love that bike!

Great follow up to the Cento1

  • Familiarity: I've put it through the wringer

Around 6 years ago, I was the first employee at Competitive Cyclist to try out the original Wilier Cento1. My first impression of the Cento1 was very good. I was taken aback by the ride quality, lateral stiffness, stability and comfortable ride quality of the Cento1. Also, the pure beauty of the Italian design was breath taking. Especially when compared to the Cervelo R3 that I was riding at the time. I was so impressed with the Cento1, that I sold the R3 and purchased the Cento1 as quickly as possible.

After I had transitioned on to other bikes, I always missed the perfection of the original Cento1. So, when I went to build up a new road bike this year, I was excited to try out the Cento1 SR. The SR delivered the same performance of the Cento1, but with a stiffer bottom bracket and head tube. The rear end of the SR is not quite as compliant as the original Cento1, but running wider rims and lower tire pressure more than makes up the difference.

As built in the photo below with a 6800 group and Reynolds Assaults, the total weight of my SR comes right in at 16lbs with pedals and cage.

I would suggest the SR for any rider that is looking for a high performance race bike, or a rider who enjoys all the benefits of a fast race bike, without any negative effects. If you are looking for a super plush ride, the Wilier Zero.9 may be a good choice. The SR and Zero.9 use the same carbon and are the same price level, but the Zero.9 uses more traditional round tubes and a seat post, with a bit more give in rear end for vertical compliance.

Please hit me up if you have any questions.

Great follow up to the Cento1

Regarding the weight. It states that the frame and fork are 1450gr, but actual weight states 1900gr. That's almost 1/2 kilo discrepancy (1.1lbs) . Is this correct?

Best Answer

Thanks for the question about the Cento1 SR. The frame and fork weights are from the manufacturer. Many of these companies take the lightest, unpainted, frame without any parts and weigh it before paint and claim that weight. Frame and fork weights are just reported from Wilier.

The ACTUAL weights are what we weighed with everything included when we shoot the photo- Bottom bracket, headset, mast topper, and anything else. They will vary a bit but 1.1 lbs is a bit surprising to me too.

If you are interested in building a bike up, let me know and I’ll get you a quote with our best pricing or answer any other questions you might have.

this bike sneaks into my favorites list

  • Familiarity: I've used it several times

A fully race-able bike that give you comfort for the longer hauls. I almost always forget this frame when I'm noting my top frames so I wanted to write a review hoping people will see it and put in in consideration with the F8, Empire, Bianchi, Cervelo and the likes. I was able to first ride the Cento1 when it first arrived in the US and wanted one right away. I will put the performance up with about any bike made, and will cost you considerably less. They led the way with aerodynamic frames and now it's all the rage, seems Wilier is always a step ahead. All this and I'm still happy climbing on it. I will say that if racing is your top priority I would go for the Zero.7, it's the little more aggressive edge you would be more happy with. If you have questions on the ride, sizing, anything on the Cento1 contact me directly at

This bike is a rocket. So fast, but still comfortable for the distance. I was hesitant due to the ISP but I accredit it for some of the long distance comfort. The BB shell on this thing is massive and along with the asymmetric chain stays you end up with crazy power transfer. I think the Ferrari comparison is rather apt, especially if you're a fan of top gear- This bike demands to be ridden and is extremely responsive- it's not twitchy but you'll definitely want to pay attention when you're at speed. Plus when you pull up at a stop light everyone in the group ride gets a little jealous. I also love that you don't see this bike very often. Definitely some pride in ownership


Sweet Ultra Machine

  • Familiarity: I've put it through the wringer

I had CC build a C1SL for me after a lot of research. I was coming from long miles on a "gentleman's bike" (a 2004 Specialized Roubaix) and although I wanted a more race worthy ride I didn't want to be crippled riding it at distance. Most US designed race bikes just hurt after 70-80 miles. The result was spectacular. The Wilier is actually MORE comfortable than my Roubaix, and every gram an aggressive race machine. With the same wheels/tires, I consistently ride 10-12% faster for the same amount of power, and most of that is because of the stiff power transfer, as well as a more aero riding position that is simultaneously easier on my back and neck. After roughly 1.5 seasons and 5100 miles, I've put it through the crucible on two double centuries, several 250+ mile training days, 4,000 ft screaming descents, and my first ultra - a 410 mile, 29,000 ft confirmation of this bike's lineage that started in the Dolomites. It is that rare combination of stiff and supple, and looks damn sexy in the peloton to boot. Only two words of caution. Definitely get a pro fit before you start cutting on the integrated seat post, as another writer mentioned. And straight out of the box, get a better, stiffer derailleur hanger. The original installed on my bike was soft as butter, and it took almost 1,000 miles to figure out why the bike wouldn't hold a tune for more than a day or two and shifted poorly accordingly. CC was super helpful. I called them 3 or 4 times and asked a million questions as I agonized over dropping $5K on a new bike. They answered all my questions, and had a lot of other suggestions as well. The Wilier is the closest thing to a Ferrari on two wheels and two cranks. It never disappoints.

What hanger did you use? Mine has a stripped bolt.

Ride like Jens

  • Familiarity: I've put it through the wringer

Yes, that Jens! This review is for a Cento 1 SL (not the SR), but the differences will be minimal. Shortly after I had CC build up my C1SL with Campy Chorus/Shamal wheels, I did get to ride with Jens (along with my son who is in the picture), and it was no trouble riding at his pace. OK, so it wasn't a race, just a Gran Fondo in TN; but this bike (I was upgrading from a Wilier Izoard w/Force) was an easy pedal for a metric century on the hills of southern TN with this 50 year old body. The major difference I've noticed is the stiffness of the BB, so much more of the power is transmitted with this bike than any other bike I've owned or ridden; especially when riding up the hills in TN or on the Hilly Hundred. But don't worry about the ride being harsh - it's a very comfortable ride for long distances. I've now ridden this bike over two thousand miles, and still haven't found anything I'd change. Can't recommend it enough. My only recommendation is to get a professional fit before cutting the integrated seat mast - I did the full Specialized Body Geometry fit and the results have been spectacular.

Ride like Jens

What an awesome ride.

    This bike is significantly stiffer than the 2009 cento uno that I had. Being a heavy rider (220 lbs), climbing usually reveals where a frame will flex and this frame is stiff at the bottom bracket and across the top tube. There's very little twisting at the head tube and with every pedal stroke the bike simply drives forward. The ride is still smooth and comfortable and I can't wait for the next 2000 miles on it.
