In this Article

Published on February 8, 2024

When it comes to choosing the perfect bike, two Cannondale models, the Synapse and the Supersix Evo, catch the attention of cycling enthusiasts. These two high-quality road bikes are designed to meet the needs of demanding cyclists, but they have distinct features that can influence your choice. Let's take a closer look at the comparison between the Cannondale Synapse and the Cannondale Supersix.

Comfort and Endurance: Advantage for the Cannondale Synapse

This model is intended for cyclists looking for comfort on long rides, rough roads, and light gravel. As an endurance bike, it features a more relaxed frame geometry. This results in a more upright and higher riding position, ideal for cyclists who prioritize comfort on extended outings. Therefore, it's perfect for long days in the saddle or for cyclists looking to avoid back and neck pain.

Downside: Its geometry may give a feeling of slowness in climbs and acceleration.
It also comes equipped with a cassette of up to 34 teeth and large 32mm tires that offer more comfort and some off-road capability. The Synapse is available in budget-friendly alloy and high-end carbon. Despite the emphasis on comfort, the Synapse remains lightweight, efficient, and fast. It allows cyclists to go further, ride longer, and explore with more confidence and less fatigue.

SmartSense Technology

Cannondale has prioritized safety with the Integrated SmartSense System on the brand new Synapse model. It's definitely cutting-edge safety technology. It integrates front and rear lights as well as a detection radar in collaboration with Garmin. The lights were developed by the Lezyne brand. A small bonus for its reflective seatstays.

Cannondale Supersix: Performance and Lightweight

For cyclists focused on performance and speed, the SuperSix EVO offers a stiffer and more responsive ride. It's perfect for fast climbs and powerful sprints. The SuperSix Evo is perfect for competition. It's a versatile bike, designed to be lightweight and agile for road racers looking to conquer big mountain stages or crush their PRs on Strava. The new model also offers aerodynamics and comfort. The current SuperSix EVO is actually 30% more aerodynamic than its predecessor, saving precious watts at high speeds.

Cannondale Supersix: The Ultimate Racing Bike

With a more aggressive geometry, the Supersix is focused on performance. It offers an aerodynamic position that maximizes efficiency, ideal for cyclists seeking optimal speed and increased responsiveness. The SuperSix Evo is often classified as a speed-oriented performance road bike.

Downside: it can be uncomfortable on long distances and it's not the best choice for beginners.
➡ In summary, if you're looking for a comfortable bike for long distances, the Synapse is an excellent choice. If you're looking for a fast bike for racing or training, the Supersix Evo is a better option.

Cannondale Synapse vs Supersix Evo: Ultimately, Which Model to Choose?

Frame Type

The carbon frame of the Synapse is generally designed to be more comfortable due to its adapted geometry. It's a bit heavier than that of the Supersix Evo, but it's also more durable. This makes it a good choice for those who want a bike capable of tackling rougher terrain. It's also a good option for those looking for a frame that will last longer.
Regarding the Supersix, Cannondale emphasizes lightness and rigidity with primarily high-quality carbon frames. This makes it a preferred choice for those seeking a responsive and high-performance bike. The Supersix Evo is a lightweight option that's perfect for racing or riding on paved roads. It's also a good choice for those who want an easy-to-handle bike. However, the downside of this frame is that it's not as durable as other options on the market.


If comfort is your priority, the Synapse excels on rough roads. Its design promotes shock absorption, offering a smoother ride, ideal for long distances. It's not dedicated to competition but to cycling as a whole. With this bike, you can do road cycling, gravel riding, and even touring. An aerodynamic bike, you can ride anywhere while being comfortable. With a tire setup of 30mm that helps dampen vibrations, this bike can easily transform into a gravel bike. Furthermore, if you're looking to get back to cycling after a long break, prioritize an endurance bike like the Synapse.

Drivetrain Group

The different models of Synapse and SuperSix are available in:
Shimano 105 (mechanical), known for its reliability and durability
Shimano 105 Di2
Ultegra (mechanical), offering good value for money compared to higher-end groups
Dura-Ace Di2, Shimano's top-of-the-line group, offering the best performance and most advanced technology. It allows you to have a lighter bike. However, it's often reserved for professional riders or very serious cyclists willing to invest in top-notch performance.
The Synapse is also offered in GRX Di2 version (specifically designed for gravel bikes, with configuration options tailored to this type of bike. It thus benefits from the advantages of electronic gear changes on rougher terrain), while the SuperSix benefits from SRAM RED AXS and SRAM Force AXS versions.

If you're still undecided between Shimano 105 or Ultegra, here's our opinion.

The first thing to consider when choosing a bike is the price. Generally, the Synapse is positioned at a slightly more affordable price, making it an excellent choice for those looking for a high-quality bike. This bike is available in several models. The Synapse Carbon 3L is the most affordable model, priced at €3,199 ranging up to €8,999 for the Synapse Carbon 1 RLE. You can also opt for a refurbished Synapse to treat yourself without exceeding your budget.

Due to its high-end features, the Supersix can be a more significant investment, but this can be justified by its exceptional performance. Also available in several models, the Carbon Disc 105 is the most affordable model and is offered at €2,899 up to €14,999 for the SuperSix EVO LAB 71.

In conclusion, the Supersix Evo and the Synapse are both excellent bikes. Your choice will depend on your personal preferences, riding style, and goals.
