Editor’s Note: After 3,400 words of Zinn wisdom, some folks simply want to know — which is better, Shimano Di2 or Campagnolo EPS? Here’s our editors’ best attempt at a shoot out:
- Quieter, smoother rear upshifts
- Available sprint-shifter buttons allow better shifting in the drops
- Slightly faster front upshift while shifting under full power out of the saddle
- Smaller, removable battery can be hidden
- Ultegra Di2 less expensive than either Campy group
- Dura-Ace Di2 less expensive than Super Record (Record is said to be comparable to Dura-Ace Di2 pricing)
- Accessory shifters for the bar tops, aero extension and aero base bar shifters currently available (Campy promises aero shifters in time for the Giro. No word on bar-top shifter plans).
- Made in Japan
- Record and Super Record are each lighter than Dura-Ace Di2
- Better shifting in thick gloves
- More distinctive shift button clicks
- Multiple rear shifts, including a full sweep of the cassette, possible with one push
- Better shifting from the drops compared to Di2 with no sprint shifters.
- Made in Italy
