SHIMANO Cycle Computer SC-E5003 E-TUBE system

Shimano SC-E5003 Cycle Computer with Assist Switch (SD300)

The SD300 port version of the SC-E5000. A combined display and assist switch that mounts on the left of a flat bar, with buttons for assist up and down, lights and the display menu. No power button.

The 1.4 inch backlit monochrome LCD shows speed, assist mode, battery level, trip, odometer and estimated range, plus gear position and auto shift mode on Di2 bikes.

Shimano's notes say it needs to be used together with the EW-AD305. Like any e-bike system part it should be fitted and set up by a workshop. Not sure it fits your bike? Talk to us and we'll check.
