How to measure sit bone distance if I am very fat? I saw many people over the Internet suggesting I sit on a cardboard with my feet a little lifted, mimicking my riding position, and then marking the place with chalk to reveal ny sit bones footprints. However, as a ~140kg man, this does not seem to work (no traces left in the cardboard), but I am unsure I did it right.
Could you kindly suggest other methods / how I could make this work? I want this in order to grab a saddle.
Many bike stores have a foam cube that you sit on for a few minutes. When you get up, the impression of your sit bones is etched in the foam and can be measured. The good bike stores will walk you through that before selling you a new saddle.
