Went to FSA website and after considerable navigating did find some spacers and washers listed. However, based on their website I was unsure which ones I needed. Called the tech line and the tech was not helpful saying that you could not use the 6700 in place of the MegaExo. Obviously MegaExo is what they sell. I called the most helpful LBS in this area and they don't mess with FSA cranks so he was unsure which ones I needed.
Any ideas which direction to go from here? Any idea which washer and spacer I would need from the FSA website?
