Trying to adjust your own bicycle fit can sometimes be like trying to paint your car while running alongside on the highway.  Not such a good idea.

There are aspects of your pedaling that simply must be observed from off the bike if correct adjustments are to be made.  Arguably, the most important of these relate to your knees.  Optimal leg extension (i.e. saddle height) is virtually impossible to accurately measure from the saddle.  "Too high" or "too low" is determined by your leg length as well as flexibility and pedaling style (flat footed, toe down, etc.).  The optimal saddle height required by any specific cyclist’s pedaling style can only be accurately determined by someone observing that cyclist pedaling against resistance.

Determining your optimal knee alignment relative to the pedal both fore/aft and laterally must also be measured by an outside observor while you’re pedaling against resistance.  Locating the knee directly above the pedal (through the use of pedal spacers, cleat adjustments, etc.) is the basic goal.  This can be performed with a plumb, with a projected laser, with video freeze-frame, with motion-capture or just eyeballed.  The more experienced the bicycle fitter the more reliable the result regardless of the method used.  The more reliable your bicycle fitting results, the more unlikely you are to experience over-use injuries.

Similar concerns apply to the fitting adjustments of your pedal cleats and saddle.  More on those later.

BTW – Love the headlights.
