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.

Shiftmate X
Shifter and derailleur combinations that we know can’t be made to work with a Shiftmate!
| Shifter | Derailleur | Cassette type and speed | Comment |
|---|---|---|---|
| Shimano 11 speed Road or MTB | Shimano 5 to 10 road or MTB, SRAM or Campagnolo | Any 5 to 11 speed | Can't be done |
| Campagnolo 11 speed | Shimano 11 road or MTB | Any 5 to 11 speed | Can't be done |
| Campagnolo 12 speed | Campagnolo 12 speed | Campagnolo 10 speed | Can't be done |
Shiftmate Y
Shifter and derailleur combinations that work just anyway without the need for a Shiftmate!
| Shifter | Derailleur | Cassette type and speed | Comment |
|---|---|---|---|
| Shimano 8 speed road or MTN (except D'Ace) | Shimano 7 speed road or MTB | Shimano 7 speed | Works 100% or the other way round but missing one sprocket |
| Shimano 11 MTN | SRAM 11 MTN | Shimano or SRAM 11 speed | Shifting ratios both linear and SO close that these just work together without the need for a Shiftmate |
| SRAM 11 MTN | Shimano 11 MTN | Shimano or SRAM 11 speed | Shifting ratios both linear and SO close that these just work together without the need for a Shiftmate |
| Shimano, SRAM or Campagnolo 11 | MATCHING 11 | Shimano, SRAM or Campagnolo 11 | Cassette space is VIRTUALLY identical so shifting is fine |
| Shimano, SRAM or Campagnolo 12 | MATCHING 12 | Shimano, SRAM or Campagnolo 12 | Cassette space is VIRTUALLY identical so shifting is fine |
