Product Details
Internal Routing
Improving on the previous SD50 model of electric wires, these SD300 wires are both smaller and lighter than their predecessors. Designed for internal routing, these wires are the magicians behind the magic of instantaneous shifting and lightning-quick signalling, all the while keeping your bike looking sleek. And with a simple-as-you-like setup, it's as easy as plugging this 650mm Shimano EW-SD300 Di2 Electric Wire into compatible accessories and riding off. Specifications
