Product Details

The EW-SD300 is a power cable which was developed for the Dura-Ace and Ultegra Di2 12-speed road bike derailleurs and the MU-UR510 hub gear motor unit respectively. It is 0.4 mm thinner than the previous EW-SD50 cable, which saves weight and has optical advantages.

There is a connector on both sides, with a diameter of 3.45 mm, which is also significantly slimmer than the SD50 model. Electrical signals are transmitted at lightning speed between the rear derailleur, battery, front derailleur and, if applicable, the STI.

Note: Di2 shifters for time trial and triathlon that require the old cable can be connected to the EW-SD300 via conversion adapter, EW-AD305.

  • Waterproof plug

Compatibility:

  • Dura-Ace Di2 R9250
