Notes
- Manufacturers measure frames differently; between two sizes, pick smaller for racing, larger for comfort, and test-ride when you can.
- Modern sloping-geometry frames make the S/M/L letter more useful than the centimeter number.
- Educational estimate for sport and training purposes, not professional coaching or medical advice.
