The Shimano EW-SD300 is the E-TUBE wire used by Shimano's 12-speed Di2 groupsets, including Dura-Ace R9200, Ultegra R8100 and 105 R7100. It's slimmer than the older EW-SD50 wire, at roughly 2.1 mm, with a smaller plug at each end.
This version is 250 mm long and made for external routing. Di2 wires can't be cut or shortened, so choosing the right length is what keeps the install tidy.
Carry a spare or swap out a damaged wire and you're back to crisp electronic shifting.
