The first step we use to plan your custom geometry is to look at your current riding position. Your body will have adapted to this riding position so we take it as a starting point and carefully consider how to improve things.

You can take these measurements yourself. You'll only need a tape measure. Just position your bike on a flat and level floor with the back wheel touching a wall (your bike should be upright and at 90 degrees / perpendicular to the wall). Then use this diagram to measure the length of each coloured line on your bike and complete the form below.
