Just after launching their amazing new XTR Di2 group, Shimano’s PRO components division unveiled a full cockpit group built to hide the wires from shifter all the way back.
Using ports on the handlebar, wires can run inside the bar, through the stem and directly into the frame. From there, the battery will sit in the seatpost or, thanks to a “new headset design”, you can stash the power supply directly inside the fork’s steerer tube.
All junction boxes can then be tucked in the tubes or stem, and a special steerer cap provides access to the front junction for charging. More pics below…
At the moment, we don’t have tech details and specs, so we’ll update as soon as we get more info. In the meantime, the pics give some of it away.
Putting the battery in the steerer would preclude using a star nut or expansion wedge, so we’re intrigued by this bottom cap design. We’ve got a call in to Shimano for details.
A removeable top cap lets you access the battery and/or Junction A for charging.
The seatpost uses their standard clip to retain the battery.
Fork steerer or seat tube, your choice. Unless you have a dropper post.
