Important Notes

• This calculator provides a starting point. Professional bike fitting is recommended for optimal comfort and performance.

• Different bike geometries (race vs endurance) may require different sizes even with the same measurements.

• If you're between sizes, consider your riding style: smaller for racing/aggressive, larger for comfort/endurance.

• Contact us for personalized sizing advice based on the specific bike you're interested in.
