Hi,

I was just wondering if it was possible to fit the 6870 Di2 on a 2012 Cannondale SuperSix ? It has no internal wiring. I think the 6870 Di2 has a new round long battery that only goes in the seat post. I don't think I could get a wire out of the top of the seat post

Here is an internet picture of my 2012 cannodale supersix

I actually own a 2013 Ultegra Di2 SuperSix EVO. I am pretty sure the 2012 uses a 27.2 mm seatpost just as the 2013 does and you can get the wires down the seat tube toward the bottom bracket. The internal battery should fit inside the stock FSA seatpost.

Attached picture is taken under the bike. There is two holes, one is the cable for front derailleur. Its a bit small but maybe its connected to the seat tube.

I've see a few people drilling a hole for the battery but it voids the warranty.
