Re: Newbie-esque problem

A more robust solution might be a couple of proximity switches
mounted on your fork reading a metal strip with holes in it mounted
to the shock tube at the wheel. The holder for the prox switches
would act as a guide for the metal strip. You should be able to get a
resolution of 4x the hole spacing; the minimum hole spacing depends
on the size of the prox switch. Andy
