SHIMANO EW-EC300 – THE CENTRAL POWER SUPPLY FOR YOUR 12-SPEED DI2 SYSTEM
The Shimano EW-EC300 charging cable was specifically developed for the latest generation of electronic 12-speed Di2 shifting systems. It is the exclusive solution for safely and efficiently charging the internal battery (BT-DN300) in the Dura-Ace R9250, Ultegra R8150, and Shimano 105 R7150 groups. Charging is conveniently done via the integrated charging port directly on the rear derailleur or, for appropriately equipped models, via the port on the crankset's power meter.
With a generous length of 1,500 mm, the cable offers maximum flexibility when positioning your bicycle in the workshop or garage. In addition to its charging function, the EW-EC300 serves as a reliable data interface: simply connect your bike to a PC to make individual settings, adjust shifting logic, or perform important firmware updates using the E-TUBE PROJECT software. The robust plug connection guarantees stable power and data transfer at all times.
