Key Measurements & What They Mean
Essential measurements like effective top tube length, seat tube length, reach, and stack dictate fit and handling, ensuring optimal comfort and performance on the SuperSix Evo.
Effective Top Tube Length (ETT)
The Effective Top Tube Length (ETT) is a crucial measurement representing the horizontal distance from the head tube to the seat tube. Unlike a traditional top tube measurement, ETT accounts for sloping top tubes common in modern bike designs, like the SuperSix Evo. This measurement significantly impacts your reach to the handlebars and overall riding position.
A longer ETT generally results in a more stretched-out, aerodynamic position favored by experienced riders and racers. Conversely, a shorter ETT promotes a more upright and comfortable posture, suitable for endurance riding or those prioritizing comfort. When selecting a SuperSix Evo size, carefully consider your desired riding style and flexibility. Comparing your current bike’s ETT to the Cannondale size chart is a great starting point. Remember, a slight adjustment via stem length can fine-tune your reach.
Seat Tube Length
The Seat Tube Length is the distance from the center of the bottom bracket to the top of the seat tube. While historically important for standover height, its relevance has diminished with sloping top tube designs like those found on the Cannondale SuperSix Evo. However, it still plays a role in determining proper saddle height and ensuring sufficient seat post insertion for safety.
For the SuperSix Evo, seat tube length primarily influences the amount of exposed seatpost. Adequate seatpost insertion is vital for structural integrity and compliance. Riders with longer legs may require a frame size with a longer seat tube to accommodate their leg length and desired saddle height. Always adhere to the manufacturer’s minimum insertion depth guidelines. Consider this measurement alongside reach and stack for a holistic fit assessment.
Reach and Stack – Finding Your Fit

Reach and Stack are modern, crucial measurements for bike fitting, offering a more accurate representation of frame size than traditional methods. Reach measures the horizontal distance from the bottom bracket to the head tube, while Stack is the vertical distance. These figures dictate your riding position – how stretched out (reach) and high up (stack) you’ll be.
For the Cannondale SuperSix Evo, matching your reach and stack preferences is paramount. A longer reach promotes a more aggressive, aerodynamic position, while a shorter reach offers greater comfort. Stack influences handlebar height; a higher stack is more upright, and a lower stack is more race-oriented. Utilize Cannondale’s geometry charts and compare them to your current bike’s measurements to find the ideal fit.
