Transfer your riding position to a new bike

Enter your well-fitting bike with saddle height, seatpost and cockpit. For every size of the new bike we calculate the stem, spacers, saddle height, setback and saddle position that reproduce the same contact points. This is a geometric approximation without guarantee and does not replace a professional bike fit.

Geometry data comes from the manufacturers' geometry tables, each linked with source and retrieval date. No guarantee for correctness – data may be wrong or outdated, calculated values and the size finder are approximations and do not replace a professional bike fit. Brand and model names belong to their respective owners; there is no affiliation with the manufacturers.
