From the same shop that sent over the limited edition Rabobank road bike pics earlier this week comes a custom Giant Anthem X 29er with Dura-Ace Di2 electronic shifting.
The rear derailleur has a custom pulley cage with relocated upper jockey wheel, and shifting is handled by Shimano’s remote pods.
While the improved wiring system on the Ultegra Di2 would make for a cleaner install, there aren’t any remote shifter pods available for that group yet. As such, Eden’s used Shimano’s standard remote shifters to handle gear changes. Here’s their words on it:
Designed and implemented by Matt LaPrade of Eden Bicycles, this is your local shop’s version of a Di2 MTB. The bike is a 2011 Giant Anthem X29er 1 retrofitted with XTR m980 and Dura-ace Di2. The pulley cage was custom cut out of 2014 aluminum to offset the upper pulley in order to clear the 36t XTR cassette. Some design features are wired in, waterproof shifter connecters, and the rear cage has multiple settings for the spring tension. The shifters are shimano satellite shifters. On the way are custom ENVE wheels. We built this bike as an engineering exercise and for customers to test ride.
