Synchronized shift and MTB derailleurs
Want to use MTB derailleurs and also synchronized shift? You need a display in order for synchronized shift to function.
The two displays I recommend are the SC-MT800 display and its more expensive XTR equivalent, the SC-M9051. Functionality-wise, they're exactly the same. It is just the casing that is different.
