This!The old shifter doesn't work at all. I played with it during our customers installs. (We had it in stock, i fiddled with it while waiting for shimano to send us the s7000 shifter)
I am just replacing the S500 with S7000 and tried to re-use the old lever, cable and the inner cable fixing bolt. Comapring to 500 series I have found that:
1) The bolt is different (cable within the bolt is routed differently) - probably due to the fact that the cable is routed from the top
2) The distance between cable stop and cable bolt is different (145 mm vs 101 mm according to the spec)
However I am somehow having the troubles to have the gears adjusted properly - the recommended 145 mm does not seem to work in my setup.
How did you guys install the bolt with your S7000 hubs? Did you take some measurements (as recommended by SH spec) or did you experiment the correct bolt position?
