Bianchi Specialissima - Ultegra Di2

As the pride of the Italian bike industry, Bianchi’s craftsmanship has always been unquestionable. Bianchi Specialissima – Ultegra Di2 12V also proves this in action.

Adopt Bianchi CV shock absorption system Specialissima Disc carbon frame and fork are lighter and can eliminate 80% of the vibration effect at the same time. Therefore, it can give the user a comfortable and light riding experience.

As the name suggests, the ultra-high-grade Shimano Ultegra Di2 12V groupset has a flattering ergonomic design, as well as more precise radio shifting and a simpler braking system. This is enough to make the Bianchi Specialissima even more superior. And a faster, more comfortable ride is more conducive to allowing riders to take places in races.

Here we break down the ride, key features, components, specifications, and other versions of the Bianchi Specialissima – Ultegra Di2 12V.

Bianchi Specialissima – Ultegra Di2 Climbing Review

To evaluate the Bianchi Specialissima – Ultegra Di2, I asked my friends Ethan and Waylon to ride a road race bike to the Northwest Loop of the Arkansas High Country Route, where we would start a three-man race. The race was a three-man race.

Although it is in Springfield Plateau, the paved Razorback Area Greenway is very soothing. The steep hills are not particularly high, though the average Climb of 80 feet per mile is still there.

However, the sweat on their foreheads as the bike climbed told me that Ethan and Waylon were pedaling very hard. I was also encouraged to pedal harder, but not only did I not feel tired, but I also found that my bike was running faster. Afterward, they also said that they didn’t lose to me, but to the light and fast Bianchi Specialissima – Ultegra Di2.

Bianchi Specialissima – Ultegra Di2 Design Reflections

The bike is worthy of being designed for competition, and every detail makes me feel its infinite charm.

First of all, the lightweight Fi’zi:k Antares R1’s Saddle made me feel extremely comfortable during the ride. There is also the WINGFLEX design, which makes me feel like my entire weight is evenly distributed on the saddle. Also, the slightly curved design of the ANTARES is perfect for me with low pelvic rotation and makes me feel like I’m gaining more power.

Not only that, the carbon Reparto Corse by FSA K-Force Light SB25 seat post supports me to easily and accurately adjust the tilt for a more comfortable riding position.

Secondly, the aerodynamically designed carbon FSA Compact HB-RK-222S shock-absorbing handlebars with Black soft Microfiber tape grips. The double damping mechanism makes me feel united in the ride, making me feel that every cell in my body is full of energy, which gives me the confidence to win.

Finally, the Shimano Ultegra Di2 groupset is certainly the perfect partner for racing. The silky smooth radio shifting is simple, so I don’t have to be distracted from the ride. With a faster tuning configuration and a faster drivetrain, what’s stopping me from winning?

Bianchi Specialissima – Ultegra Di2 Flatland Racing

Compared to the more strenuous uphill movement, flat racing is also the most important racing section in general events. We also came to a flatter road for testing.

The radio shifting system is so friendly! The simple and precise operating system makes the whole shifting process very smooth and silky. Therefore, I was only concerned about what kind of force to pedal with and just control the faucet, because the speed was not losing to them at all. Since I was always in the front, unfortunately, I couldn’t see Ethan and Waylon’s arduous riding process.

To its credit, right after Oltre, all Bowdens and electronic shifting cables are integrated within the handlebars and frame with the help of FAS’s ACR system. Not only does this make the cockpit ride cool enough for me, but the fact that it is so aerodynamically designed makes the ride smooth and unobstructed.

Main Features

Frame Group

Unlike the usual carbon construction, the frame and fork of the high-performance Specialissima Disc carbon, with the addition of the Bianchi CV damping system, the owner of the Bianchi Specialissima not only finds it hard to feel muscle fatigue but also gets more energy. If you think it only works to eliminate 80% of the effects of vibration, you’re wrong. Lighter weight, high stiffness, and high strength are equally sought after by Bianchi.

In addition, at only 750g, the carbon disc brake mount won’t waste your power at any time. It delivers power brilliantly to the road, whether it’s on a steep hill or on the flat, to help you win the race. That’s what it’s ultimately after.

One more thing, Bianchi’s signature Celeste craftsmanship with a fully concealed internal alignment design gives the body less air resistance while the bike looks very beautiful and generous.


As a road racing bike, speed is the primary pursuit of the racer. Therefore, low wind resistance and comfortable geometry are just as important as a comfortable, damped body build. And Bianchi understands this, so the Stack/Reach Ratio (1.39, 55cm size) is adventurous enough to adopt an aggressive geometry position in exchange for less air resistance. And the higher reach (Stack 540, 55cm yards) gives the rider a lower windward area while allowing the rider’s center of gravity to shift forward to help them transfer power to the pedals efficiently.

In addition, a steep Seat Tube Angle (73.5°) with a Head Tube Angle (72.5°) is quite common on racing bikes. This is something riders who need to maintain the same seating position for long periods have long been used to.

In general, the geometric posture of the Bianchi Specialissima is on the aggressive side. But the uncomfortable feeling that this posture may bring is perfectly eliminated by the Saddle of Fi’zi:k Antares R1.

Components and Specifications

Shimano Ultegra Di2 12SP Drivetrain

Bianchi Specialissima - Ultegra Di2 Shimano Ultegra Di2 12SP Drivetrain

An integral part of Shimano’s 12-speed road bike lineup, the Shimano Ultegra Di2 R8100’s seamless 12-speed modified Ultegra R8100 disc has a faster, more efficient drive with the strength of the Shimano Dura-Ace Di2. as a result, you get all the benefits of the Dura-Ace system at a cheaper price.

Unlike the previous disc brake versions, the new Ultegra R8100 is purely electronic, handling the shifting process more efficiently and safely. And the CR1632 battery in the shifter has a tremendous electrical capacity that can support 1.5-2 years of riding. And, it is also very easy to charge, directly from the rear of the machine, with no need to reconfigure the bike junction box. In addition, the rear derailleur adds a function button that supports switching between shifting modes (synchronized and semi-synchro) without the need to connect to E-tube.

In addition, Ultegra’s cranks are available in 160-175mm lengths, which also better fit petite, triathlon, and riders with special biomechanical requirements.

“Faster, but not intense” is the truest assessment of the Shimano Ultegra Di2 drivetrain by the majority of riders. Therefore, for road racing, Shimano Ultegra Di2 12SP can be said to be impeccable.

Shimano Ultegra Di2 12sp Hydraulic Disc

Bianchi Specialissima - Ultegra Di2 Shimano Ultegra Di2 12sp Hydraulic Disc

Shimano Ultegra Di2 12V hydraulic disc will always make you feel like road riding has never been more fun. That’s because of the redesigned wireless Ultegra ST-R8170 disc calipers, which have a smaller structure, but the system is quieter than ever and keeps the cockpit cleaner and easier to maintain.

In addition, the tried and tested Servo Wave technology enhances the initial braking point, making braking faster and more precise, taking bicycle road braking to another level. And the optimized brake control system allows you to brake with lighter, smoother movements.

The new Di2 platform used in Dura-Ace and Ultegra also gives users faster, more reliable wireless electronic shifting technology, unlocking the shifter to the rider.

Pirelli P ZERO™ Race Tires

Bianchi Specialissima - Ultegra Di2 Pirelli P ZERO™ Race Tires

Developed over three years, the ultra-lightweight quality Pirelli P ZERO™ Race tire has long been the race tire of choice. As an all-around race tire, it integrates all the advantages of an open tire.

First of all, the FGD lightning-type tire pattern design originates from the technology and analysis of SBK. It ensures that the body is stable enough at any moment, allowing the rider to confidently make all kinds of drastic maneuvers, such as sprinting and hard braking.

Secondly, the Pirelli P ZERO™ Race tire, which is always mixed with the World Tour, has a new SmartEVO compound that gives it an even better performance in competitive races.

The three different polymers give the tire an optimal balance of grip, endurance, and weight. As a result, the lightweight Pirelli P ZERO™ Race tires offer excellent grip on both dry and wet surfaces, while having the lowest rolling resistance.

In addition, the TechWALL+ cord ply technology that adds a layer of high hyper-cut fabric under the table. This gives the tires a stronger box sub-protection capability while still allowing the tires to roll with maximum efficiency.

Therefore, you should trust the common choice of various World Championship competitors. With the support of Pirelli P ZERO™ Race tires, the Bianchi Specialissima – Ultegra Di2 gives you a powerful boost in the race.

To their credit, if you prefer vacuum tires, 2-WAY FIT tubeless ready rims are also supported. But that means you have to pay more bills to maintain it.

Other versions of Bianchi Specialissima

Bianchi Specialissima - Red eTap AXS

If you ask me what is the biggest difference between the Bianchi Specialissima – Red eTap AXS and the Bianchi Specialissima – Ultegra Di2. The names of both already tell us the answer. So rather than the difference between the two bikes, it’s the difference between SRAM and Shimano in terms of groupset and other small accessories.

I have to admit that SRAM’s top-of-the-line Red eTap AXS kit does have superior performance to the Shimano Ultegra Di2. Although both are wireless shifting, it is a lighter and smoother shifting experience. And faster braking is something you can feel directly on the Bianchi Specialissima – Red eTap AXS.

In addition, there is a difference in the shifting logic of the two. You can shop around according to your habits. If you prefer the fast and rough handling of the American style, the Bianchi Specialissima – Red eTap AXS is indeed a good choice. But if you prefer delicate and precise handling, the latter can also satisfy you.

Canyon Ultimate CF SLX 9 Di2 vs Bianchi Specialissima – Ultegra Di2

Canyon Ultimate CF SLX 9 Di2

Although the Canyon Ultimate CF SLX 9 Di2’s groupset all use the more advanced Shimano Dura-Ace Di2 R9200, the Canyon Ultimate CF SLX 9 Di2 does not show a significant advantage in terms of speed.

In addition, it loses out to the Bianchi Specialissima – Ultegra Di2 in terms of other accessories that affect user comfort, such as tires, saddle, and seat post, because the Canyon Ultimate CF SLX 9 Di2 strikes me as inferior to the latter in terms of riding comfort.

Therefore, I prefer the Bianchi Specialissima – Ultegra Di2, and I believe the carbon frame that gives me such a subjective feeling is also because it has shock absorption.

Trek Emonda SLR 7 eTap vs Bianchi Specialissima – Ultegra Di2

Trek Emonda SLR 7 eTap

The Trek Emonda SLR 7 eTap, which tends to be an SRAM sub-top accessory, also has the SRAM Force eTap AXS groupset written into the name. As mentioned before, there is a difference in the shifting logic of the two. Therefore, it’s hard to say which is better than the other between SRAM Force eTap AXS and Shimano Ultegra Di2, we can only say that One man’s meat is another man’s poison.

To its credit, the Trek Emonda SLR 7 eTap is quite passable in terms of racing performance. And the Bontrager Aeolus Pro 37 OCLV carbon vacuum wheelset is used, but that means you’ll have to put in more effort to maintain the tires.

If I had to say which one of them is better, I think the Bianchi Specialissima – Ultegra Di2 is better value for money. Because its damping effect and shifting logic impress me more.

Specialized Tarmac SL7 Pro – SRAM Force eTap AXS vs Bianchi Specialissima – Ultegra Di2

Specialized Tarmac SL7 Pro - SRAM Force eTap AXS

The Specialized Tarmac SL7 Pro – SRAM Force eTap AXS is also a favorite of the SRAM Force eTAP AXS, and frankly, I was a little disappointed with its performance.

Because the same aggressive geometry angle does not bring a speed advantage. And the slimmer, narrower tires (700x26mm) force the bike to have less passing power, again without the speed advantage.

Overall, the Specialized Tarmac SL7 Pro – SRAM Force eTap AXS is still a long way from being the best race bike in my mind.

Focus IZALCO MAX 9.9 vs Bianchi Specialissima – Ultegra Di2

Focus IZALCO MAX 9.9

The Focus IZALCO MAX 9.9, which also focuses on speed and comfort, is also impeccable in terms of both speed and component extraction.

However, I think the Bianchi Specialissima – Ultegra Di2 shows a more refined control of details. Whether it’s the shock-absorbing frame and fork, or the more shock-absorbing seat post and grip, it strikes me as sincere.

Riding a race is a more permanent practice, so it takes enough comfort to give the rider more confidence to keep going. I think the Bianchi Specialissima – Ultegra Di2 does that and makes me feel it is worth every penny.
