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:

Advantage Di2:

  • 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

Advantage EPS:

  • 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
