Wilier Triestina USA have produced a new version of their Cento 1 road race bike modified for use with Shimano's Dura-Ace Di2 electronic drivetrain.

The Cento1 Di2 frameset has the same superlight carbon monocoque construction and performance features of the standard Cento 1, but adds internal routing for the wiring that connects the Di2 battery with its electronic shifters and derailleurs.

Devin Walton, director of media relations for Shimano North America, said: “While performance was the key pursuit in the development and use of the Shimano Dura-Ace Di2 electrically actuated shifting system, the side benefit is the freedom and creativity afforded frame makers with respect to cable routing.

"Wilier’s new frame design takes advantage of that benefit and with the special accommodations for the battery pack creates historically sought-after integration of frame and controls without any impact on shifting response.”

Angelo Cilli, Wilier Triestina USA's co-owner and founder, said: “We’re excited about the promising new age being ushered in by Shimano’s electronic groupsets for road and time trial bikes. In the past, attempts were made by other manufacturers to offer electronic shifting, but after extensive in-house testing we have become believers that this technology by Shimano has been refined to the point of being truly feasible and relevant."

He added: "Campagnolo is promising release of its own electronic drivetrain in the near future, so it seems that the technology may finally be here to stay."
