| What it is The Shimano EW-SD300 Di2 Electric Wire is the current-generation Di2 cable for Shimano's R8150 (Ultegra Di2), R9250 (Dura-Ace Di2) and newer Di2 groupsets. It replaces the older EW-SD50 cable used on previous-generation Di2 systems - the connector format is different, so EW-SD300 and EW-SD50 are not interchangeable. Variants Available in numerous lengths to suit any frame routing: 200mm, 250mm, 300mm, 350mm, 400mm, 450mm, 500mm, 550mm, 600mm, 650mm, 700mm, 750mm, 800mm, 900mm, 1000mm, 1200mm, 1400mm and 1600mm. Select the length that matches your bike's internal routing requirements - measure from connection point to connection point before ordering. | Price from £25.00 up to £31.99 Compare prices and buy Shimano EW-SD300 E-tube Di2 Electric Wire EWSD300IL140 Compare prices3→ |
