Another picture. For all those who remember front derailleurs, you will figure out the weird cable routing at the pinch bolt.

I modeled a filing area for the cable run on the arm of the FD-M565 based on measurements transposed from a Tiagra FD-4601.

To get a 10 speed shifter to mate with a 9 speed cassette and a 9 speed chain, I got inspiration from an old Shimano backward compatibility blurp deeply buried on the St. Sheldon site. In reality, it works, but is not perfect - the spring in the rear derailleur needs to be very strong to hit the small sprockets quickly - the problem being the angle of the inner cable entering the outer on the rear derailleur is too constrained. Not an issue normally, but this bike was built for speed on fire roads and getting it to shift fast into a higher gear was a bit frustrating.
