What we like about it: For top aero bikes, it’s not simply about stacking hardware, but more about the design of the bike details, so I think the tried and true SystemSix Hi-MOD carbon frame, Cannondale SystemSix Hi-MOD Ultegra Di2’s ever-evolving ride geometry makes more people recognize.
What we don’t like about it: It’s for a narrow crowd, and it takes a lot of movement to get the full performance of the Cannondale SystemSix Hi-MOD Ultegra Di2 very well.
Rating: (4.9/5)
Introduction
It’s a time of limits, and every field is constantly striving to push the limits. Athletes are pushing the limits of their physical abilities and skills, while bicycle manufacturers are trying to get even one percent better through the use of new materials and innovative designs. It will cost them a fortune, but I think it’s worth it. Because it represents the determination of mankind to continue to develop and progress.
As a veteran cyclist, I’m not only passionate about training myself physically and technically, but I’m also obsessed with the latest, top-of-the-line bike innovations. Now I present to you Cannondale’s latest and greatest aero bike, the SystemSix Hi-MOD Ultegra Di2.
Below I break down the Cannondale SystemSix Hi-MOD Ultegra Di2’s riding performance on the road, key features, components and specifications, and other versions.
Cannondale SystemSix Hi-MOD Ultegra Di2 Riding Performance
First: The Perfect Aerodynamic Design
Even though Cannondale SystemSix Hi-MOD Ultegra Di2 has been updated several times, every time I see it, I still exclaim: “It’s so beautiful!”. It was a wind tunnel-tested perfection with all the redundant parts deleted. Every part of it was designed to get the least amount of air resistance during the ride.
Some of you may think that I’m not a cyclist and don’t need anything aerodynamic for my daily commuter rides. In all honesty, I thought the same thing earlier in my life. But as I learned more and experienced more models, I realized I was wrong.
Aerodynamics can take a toll on your ride as long as you ride faster than 15 km/h, a speed that almost everyone can reach.
As speed increases, air resistance increases exponentially, so an excellent aerodynamic design is essential. And the Cannondale SystemSix Hi-MOD Ultegra Di2’s Customized Airfoils represent a custom truncated airfoil shape for each part of the frame, fork, and seat post, which effectively reduces drag in the yaw range.
In my riding experience, there was a very noticeable sense of efficiency. Not only was the pedaling efficiency, but also the bike was much smoother during the glide. Especially when coasting downhill, I even had the illusion that someone was not pushing me forward from behind.
Second: Continuous Optimization Of SystemSix Hi-MOD Carbon Frame
Cannondale’s BallisTec Hi-MOD Carbo has a premium high-strength, high-stiffness carbon construction, resulting in an extremely light, lively, and durable frame.
In my riding experience, comfort is not a consideration for the top aerodynamic models. Because the point of their birth is to constantly pursue extreme speed and limits. But Cannondale SystemSix Hi-MOD Ultegra Di2 surprised me a lot. Its riding comfort is fantastic in its class. SystemSix is based on the meaning of the frame, fork, seat post, bars, handlebars, and tires designed together as a whole to minimize drag, improve comfort and increase rigidity for maximum speed.
Third: More Forgiving Road Adaptability
This is a pavement-only bike, and the 700 x 25c tires are relatively fragile and won’t stand up to gravel bumps. But it’s comforting to know that the Cannondale SystemSix Hi-MOD Ultegra Di2’s rims support wider tires, which will improve some real-time and durability. This allows you to ride without worries even on roads that are not very flat. So I highly recommend equipping relatively thick tires for daily training days, so that you don’t have to worry too much about the risk of flat tires during the training process. Although this will increase air resistance and make my ride more tiring, isn’t that what I’m looking for? This is the equivalent of weight training, increasing the intensity of training.
Main Features
Frame
First of all, the SystemSix Hi-MOD Carbon frame is extremely rigid. In my riding experience, I could feel that the force drivetrain of my pedaling was very strong, especially when I was cranking the tire left and right, and the experience was really good. The traction in turns is also very good, again thanks to the rigidity of the bike. Because I can turn fast on the Cannondale SystemSix Hi-MOD Ultegra Di2, the unexpected agility and stability allow me to turn faster without worrying about the balance of the bike.
Geometry
First of all, the geometry of top aerodynamic bikes is similar because the best designs are similar. This is by the laws of nature.
Second, the SystemSix in Cannondale SystemSix Hi-MOD Ultegra Di2 refers to the overall design of the frame, fork, seat post, bars, handlebars, and tires together, which is also the origin of its name.
Third, the Cannondale SystemSix Hi-MOD Ultegra Di2 is finely adjusted for each geometric angle data in different sizes, so you must pick the right size. This way you can get better ergonomics.
Components and Specifications
Shimano Ultegra Di2 R8150
It is Shimano’s latest and greatest 2×12 electronic conventional system. The biggest feeling in my riding experience was the extremely fast-shifting, allowing me to just focus on riding hard. official Shimano figures say it is 58% faster than the previous generation Dura-Ace, which is highly consistent with my experience. And it’s compatible with 28-34t low sprockets for maximum range and compatibility.
Shimano Ultegra Di2 R8170 Hydraulic Disc
Shimano’s new and brilliant 12-speed Ultegra kit not only takes shifting up a notch but further improves on the already great Shimano road caliper design and performance. The system features Shimano’s Servo Wave for truly optimized brake contact points, so enhanced modulation provides more braking control.
As we all know, it is very dangerous to brake hard to slow down on a fast downhill. And in my riding experience, the Shimano Ultegra Di2 R8170 allowed me to apply top-notch braking on descents. This is a very incredible improvement.
Plus, a fully wireless compatible shifter means an easier installation process, simpler maintenance, and a clean look for your cockpit setup.
Vittoria Rubino Pro Speed Tires
First of all, it is one of the fastest pairs of tires ever made. The very wide disc design provides less drag over a wide range of yaw angles. I’m sure you are as impressed as I am with the exaggerated rims of the Cannondale SystemSix Hi-MOD Ultegra Di2. Hollow gram 64 KNØT, carbon, 20 h front, 24 h rear, 64 mm deep, IW 21 mm. This design allows me to get huge forward inertia while riding and is light and breaks the wind outstandingly.
Other versions of Cannondale SystemSix Hi-MOD Ultegra Di2
I will use the SystemSix Hi-MOD Ultegra Di2 as a comparison.
The model has two main upgrades compared to the model. The first is the drivetrain, from the Shimano Ultegra Di2 1×11 to the Shimano Ultegra Di2 R8150 2×12. This is a whole drivetrain upgrade, and the progress is huge. And the shifting range, speed, and feel have all been significantly improved. The second is the upgrade of the Front Hub and Rear Hub. The Front Hub and Rear Hub have been upgraded from the model’s 12x104mm front and 12x146mm rear to the front and rear (F) HollowGram KNØT, sealed bearing 12x100mm center lock / (R) HollowGram KNØT, 12x142mm, which not only improves the ease of replacement but also enhances the unity.
You may not think these improvements are significant, but you need to understand that the closer you get to a perfect design, the less room there is for improvement. This is the result of a marginal effect. So I am personally very satisfied with the progress of the Cannondale SystemSix Hi-MOD Ultegra Di2.

Cannondale SystemSix Hi-MOD Ultegra Di2 VS Trek Madone SLR 6 Gen 7
The Trek Madone SLR 6 Gen 7 is also a highly distinctive aero bike that I would find in a crowd of aero bikes at a glance. Of course, not because of the special color, but because of the special Madone aero carbon internal seat mast cap.
Secondly, the Trek Madone SLR 6 Gen 7 equipped Shimano R7150 Di2 is also good enough, but still a bit short of the Cannondale SystemSix Hi-MOD Ultegra Di2 equipped Shimano Ultegra Di2 R8150. In my riding experience, the shift speed is not as fast as Shimano Ultegra Di2 R8150.
Finally, the Trek Madone SLR 6 Gen 7’s 800 series OCLV carbon material is Trek’s selling point. But in my actual riding experience, I did not experience any significant difference with other carbon of the same class of aero bikes.
So I think the Cannondale SystemSix Hi-MOD Ultegra Di2 is the better choice for the same price.

Cannondale SystemSix Hi-MOD Ultegra Di2 VS Giant Propel Advanced, Pro 0 Di2
First of all, both cars are priced at $8,000. But at first glance, the Cannondale SystemSix Hi-MOD Ultegra Di2 looks more futuristic. Because its aero design is more obvious, while Giant Propel Advanced, Pro 0 Di2 doesn’t look very different from ordinary road bikes.
Secondly, the Cannondale SystemSix Hi-MOD Ultegra Di2 is a carbon frame and fork, while the Giant Propel Advanced, Pro 0 Di2 uses a composite frame and fork. There is no doubt that the carbon frame and fork are more in line with the future development trend. They also use the same Shimano Ultegra Di2 R8150 drivetrain and an almost identical geometry design. These will not be repeated.
In my actual riding, I didn’t experience a bigger difference either. But the Cannondale SystemSix Hi-MOD Ultegra Di2 is more comfortable to ride and better suited for longer rides.

Cannondale SystemSix Hi-MOD Ultegra Di2 VS Cervelo S5 Force eTap AXS
First of all, the Cervelo S5 Force eTap AXS is a great car. Although it is $400 more expensive than the Cannondale SystemSix Hi-MOD Ultegra Di2.
First of all, the Cervelo S5 Force eTap AXS has a very distinctive headtube. It will make my riding position more aggressive, so I will ride with less wind resistance, but it will also make me more prone to fatigue.
Secondly, the Cervélo S5 Force eTap AXS is equipped with the SRAM Force eTap AXS 2×12 drivetrain, which is in the same class as the Cannondale SystemSix Hi-MOD Ultegra Di2 equipped with Shimano Ultegra Di2 R8150. But the SRAM feels crisper and more powerful, with a distinct sense of rhythm, while the Shimano is soft and dense. It’s not good or bad, it depends on what kind of feel you prefer.
Last but not least, the Cervélo S5 Force eTap AXS is equipped with the SRAM Force AXS 48/35 with Power Meter.
So my advice is to consider the Cervelo S5 Force eTap AXS if you need a power meter and can live with a more forward-leaning seating position. Otherwise, the more affordable and more comfortable riding position of the Cannondale SystemSix Hi-MOD Ultegra Di2 would be a good idea.

Cannondale SystemSix Hi-MOD Ultegra Di2 VS Bianchi Oltre PRO – Ultegra Di2
First of all, I appreciate the Bianchi Oltre PRO – Ultegra Di2, but I don’t fit it very well myself. Compared to the Cannondale SystemSix Hi-MOD Ultegra Di2, the Bianchi Oltre PRO – Ultegra Di2 has a shorter head tube length – 118mm, while the Cannondale SystemSix Hi-MOD Ultegra Di2 head tube length is 149mm. brings a more forward-leaning riding position, putting more pressure on my arms. This is not a problem for elite athletes, but it’s not too friendly for me, a middle-aged man with a back injury. Other geometric data, only a few millimeters of difference, will not be repeated.
Also, regarding the price, the price of £6,999 is very competitive. So my advice is that if you are an elite athlete without injuries, the Bianchi Oltre PRO – Ultegra Di2 is the more cost-effective option. Conversely, if you want to experience a more comfortable aero bike, Cannondale SystemSix Hi-MOD Ultegra Di2 is a good choice.
