Shimano SM-PCE02 PC Link Cable - Upgrade SM-PCE01 to SD300 12Spd Di2 Plugs
The stand SM-PCE01 PC Link cable has an SD50 plug and therefore cannot be used with the SD300 12Spd Di2 components. Upgrade your SM-PCE01 to be compatible with the new 12Spd SD300 Connections with this SM-PCE02 PC link cable.
