MECHANIC’S DURA-ACE DI2 MOUNTAIN BIKE

Shimano Di2 for Mountain Bike

Shimano Di2 for MTB. We converted a road Dura Ace rear derailleur to use on a mountain bike. It works just as well as a road rear derailleur. We chosse to only add the rear fro simplicity sake. go to roadworxli.com for more pictures and info.

HACKTASTIC! JULIE BRESSET’S MECHANIC’S DURA-ACE DI2 MOUNTAIN BIKE

posted by Tyler (Editor) - September 9, 2012 - 10am EDT

We’ve seen more than a couple Di2 hacks on mountain bikes (here and here, for example), most using K-Edge’s Ki2 adapter kit. What we haven’t seen is a straight up Dura-Ace Di2 installation or the use of Shimano’s TT bar end button pods to get things dirty.

On display in SR Suntour’s booth was sponsored rider (and 2012 XC Olympic gold medalist!) Julie Bresset’s team mechanic’s bike that had at once both the cleanest and dirtiest conversion we’ve seen yet. While K-Edges button pods are smaller, it’s hard to argue with the aesthetics of using Shimano’s own TT pods with a custom carbon fiber mount. The only downside (besides the cost of replacing them if they snap off in a wreck) is that the up and down buttons are in pretty close proximity for the rough ‘n’ tumble arena of mountain biking, potentially making mis-shifts more likely…

Takes a lickin’ and keeps on shiftin’.

Here’s where things get a bit dirty. The custom molded junction box keeps things in place…

…and cable wrap holds the wires alongside the rear brake hose.
