No, the Mach 4 SL is not  Shimano Di2 compatible. It has a Di2 battery port and Pivot’s Cable Port System for simple routing but it is missing the holes in between the front triangle and swingarm. Pivot does not endorse drilling holes in your frame. It is possible to externally route the wire to the rear derailleur, but it will not have the same level of integration as some of our other models. If you want electronic shifting, the Mach 4SL is SRAM Eagle AXS compatible (which we offer in our XX1 Team and World Cup XC builds).
