Shimano Road Bike Electronic Components

Shimano Dura Ace and Ultegra DI2 electronic groupset components offer a huge difference in terms of user input over their mechanical counterparts. Reliable gear changes are guaranteed and as easy & soft as a mouse click. Shimano Di groupset weights are very similar to their mechanical cousins, there is no disadvantage to running Shimano DI components, except you will need to charge the battery.
