Get the inside scoop on the Shimano Dura-Ace Di2 ($4700 and up) in this Triathlete Buyer’s Guide Photo Gallery Spotlight.
After more than a couple failed attempts by others in the past, electronic shifting is here to stay, thanks to Shimano’s impeccable Dura-Ace Di2 group. Heading into its third season, Di2 has proven that it shifts faster and more precisely than anything else, and that the batteries are dependable, long-lasting and quickly rechargeable. The simple touch-button shift levers work especially well on aerobars because not only are they easy to reach and use, but they also eliminate the long runs of internal cabling that often degrade shift performance and are difficult to maintain. The downside? All this technology comes at a price—almost $2000 more than standard, mechanically actuated Dura-Ace.
