That setup is ok but I tried another. The wrist strap of the Polar is a kind of a rigid plastic. It wasn't really designed to be pinched as in the photo. Eventually it will crack. So instead I use the foam padding that was left over from the carpet layer. Its light and disposable. Wrap the foam around the handlebar and have the Polar strapped around that. It also acts like a shock absorber. So road vibrations will not travel directly to the Polar unit as in the photo.
