  • What are the “I'll-never-go-back” kind of benefits?  
    • Di2 components can be adjusted in fine increments to ensure smooth, noise free shifting.  Because there is no metal shifting cable to stretch, kink, or wear out, once your bike is adjusted correct, it stays that way.
    • The 2016 Shimano Di2 design uses electronic wires instead of metal shifting cables.  Also, a handpedal mounted Di2 shifter carries the feature of being able to press &hold down a button to rapidly shift through gears.
