Size finder · transfer your fit

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.

Your bike – how you sit today

Saddle

mmmmmm

Cockpit

mmmm°

Saddle: 208 mm behind · 689 mm above BB
Handlebar: 488 mm ahead · 630 mm above BB
Saddle–bar: 696 mm · drop 59 mm

Saddle height: bottom bracket centre to top of saddle along the seat-tube axis. Saddle fore/aft: + forward, − back. Spacers incl. top cap, handlebar centre = stem clamp.
