All Shimano derailleurs (road up to 10 speed, mtn up to 9 speed) are functionally the same, except for Dura-Ace 8 speed. Concern needs only to be given to cage widths. Avoid using a narrower cage with a wider chain size.

*Except Shimano Tiagra 4700 10 speed shifters and rear derailleur

2001 and newer Campagnolo shifters and derailleurs are not compatible with older versions.

For rear derailleur installation

For matching Campagnolo 11s Ergo Shifters with wide Shimano 11s cassettes using the 10s Shimano mech which was originally designed for max 36t.
In practice with some adjustment of the ‘B’ stop screw 40 and probably 42 are achievable.

This solution WILL NOT WORK with any Shimano 11 speed mech.
