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.
