Other factors to consider beyond height
While height is a fundamental factor, achieving the ideal bike fit is a nuanced process. Here are some insights to guide your decision.
- Brand-specific sizing. Every bike brand has its unique sizing metrics. For instance, a size 51 Cannondale CAAD13 might differ from a size 51 Cervelo Caledonia. Use the Stack and Reach measurements for a more accurate comparison over generic size labels.
- Stack and reach. If you have an existing bike that is comfortable to ride, you can use its stack and reach as a starting reference point. These can be found in the frame geometry chart below.
- Reach is the horizontal distance from the bottom bracket to the head tube’s center. It plays a pivotal role in determining your riding posture. A longer reach offers an aggressive stance, while a shorter one ensures comfort.
- Stack is the vertical distance from the bottom bracket to the head tube’s top. It influences the relative height of the handlebars to the saddle, with a higher stack providing a more upright position.
- In-between sizes. If your measurements fall between two sizes, which is common, then I’d suggest choosing the smaller size. This provides more flexibility for adjustments later on.
- Go for a test ride. Consider visiting your local Cannondale dealer, trying out various sizes, and selecting the one that feels the most comfortable.
