Not to shill, but just adding to the thread. I charge $250.00 for a Retul fit. That seems to be the standard for a fitter utilizing the Retul system tool whether they are Certified by Retul or not. I have seen upwards of $500.00 for a fit.
A fit from me takes anywhere from 90min to 3+hours. This includes a full biomechanical/physical assessment, cleat adjustments/basic shims if needed (usually not needed

), bike adjustments, full Zin

Good luck and let us know how it turns out.
