2023 Cannondale SuperSix EVO Size Charts and Guide

This guide provides a detailed sizing chart to help you find your ideal Cannondale SuperSix EVO bike size.

According to Cannondale, the SuperSix EVO frameset’s geometry is designed for speed and aerodynamic efficiency, reflected in its ultra-light carbon construction and low-drag design. This geometry puts the rider in an aggressive position, ideal for road racing and achieving PRs.

Consider the Cannondale Synapse for a more comfortable (endurance) geometry.

There are eight Cannondale SuperSix EVO frame sizes available for cyclists with height from 5’3″ to 6’6″ (160 to 198cm).

Bike size	Rider height (in)	Rider height (cm)
48	5’3″ to 5’7″	160 to 170
51	5’5″ to 5’9″	165 to 175
54	5’7″ to 5’11”	170 to 180
56	5’10” to 6’1″	177 to 185
58	6’0″ to 6’3″	182 to 192
60	6’2″ to 6’6″	187 to 198

Important things to consider

Here are important things to consider based on my experience from working at the bike shop and owning many bikes in the past.

Sizing is different across brands

Cannondale categorizes the SuperSix EVO into values like 44, 48, 51, 54, 56, 58, and 61.

These labels provide a general indication of the frame size. However, these labels may not be consistent across different bike makes. What constitutes a size 48 in a Cannondale might be different in another brand that uses a similar sizing, such as Cervelo R5 or Specialized Tarmac SL8.

Therefore, relying on these labels alone can be misleading.

Understand the frame’s stack and reach measurements

If you already own a bike that fits you well and is comfortable, use that as a reference point. 

Find out its Stack and Reach measurements and compare them against the Cannondale SuperSix EVO’s measurements. Pick the closest size.

• Reach is the horizontal distance from the bottom bracket to the center of the head tube. It determines how stretched or compact your riding position will be. A longer reach results in a more stretched-out, aggressive riding posture, while a shorter reach promotes a more upright position.
• Stack is the vertical distance from the bottom bracket to the top of the head tube. Stack height influences how high your handlebars will be relative to your saddle. A higher stack leads to a more upright riding position, which can be more comfortable, especially for longer rides, older riders, and those with less flexibility on the lower back.

The Stack and Reach measurements can be found on the Cannondale SuperSix EVO’s frame geometry chart below.

What to do if you fall between sizes?

It’s common to fall between two bike sizes for the Cannondale SuperSix EVO.

If that’s you, there are many things to consider, such as your legs-to-torso proportions, the type of bike (race vs endurance), and the final look of the bike, taking into consideration the number of spacers, stem length, and the amount of exposed seatpost.

Having said that, generally, I’d recommend sizing down (go for the smaller of two sizes) for most cyclists.

The smaller frame has more room to extend reach, and increase stack. It’s easier to make a smaller frame bigger than vice versa. However, there is a limit to these corrective measures to avoid having too many spacers (30mm+) or too much exposed seatpost, which makes the bike look out of proportion.

The smaller frame is also stiffer, more maneuverable, and marginally lighter. If set up right, it’ll have more exposed seatpost, leading to more comfort due to increased seatpost flex.

If you have a normal legs-to-torso proportion, opting for the smaller size would be a better choice.

• If you have long legs with a shorter torso, consider sizing up to avoid having too much exposed seatpost. Most seatposts are 300 to 400mm long and have a minimum insertion length to ensure safety.
• If you have short legs with a longer torso, consider sizing down and using a longer stem to extend reach.

Try before you buy

Visit your local Cannondale dealer to test different sizes to get a feel for what suits you best. Most large and reputable Cannondale dealers can provide a test ride if they have the bike in your size in their demo fleet.

Get a professional bike fit

According to Tara Lazarski, who is a physiotherapist who has worked with pro cyclists,

Consider a professional bike fit as a good investment for your cycling career. A bike fit helps you avoid issues like chronic knee or back pain, and for most riders, a proper fit will also feel more comfortable and help them pedal more efficiently.
