Park Tool Electronics 3-Way Tool EWS-1 (11-Speed Di2 Only)

A handy tool designed to make installation and removal of bicycle electronic shifting wires and batteries quick and easy.

The durable composite body features our iconic three-way wrench shape and prevents scratching of expensive components. Angled ends allow for safe installation and removal of Shimano® Di2® E-Tube® wires in tight spaces.

Universal coin cell tool helps remove and install battery covers on SRAM® eTap® and other electronic accessories.

Please note, this tool will not work for the newer 12-Speed Di2 (which has a smaller diameter plug and wire).
