Bicycle Saddle Fitting Tool

Impetus Design's saddle fitting tool allows you to switch between saddles on your bicycle.  The tools two arms locate the same width on each saddle allowing you to mark and measure to the same location every time.  This tool works best when recording your current saddles possition relative to the handle bar center or the bottom bracket center.  It can also be used to easily translate your saddle position relative to the bottom bracket center from one bike to the other.  For example from your road bike to your mountain bike.
