- If you are between sizes, the better choice depends on riding style. Many riders choose the smaller size for agility and the larger size for stability.
- Height is a good starting point, but inseam, reach, flexibility, and bike geometry all matter for final fit.
- Road bike size is usually estimated in centimeters from rider height. A typical medium adult range often lands somewhere in the low-to-mid 50 cm frame range.
