I know this is a Zombie post, but to avoid rehashing the same question, has anyone completed a Di2 installation on a Slice frame?
Any luck with getting the battery to live inside the seat tube?
And does adding an adaptor to the BB30 to make it Shimano-compatible reduce the stiffness of the frame?
I'm guessing that frame stiffness is more of an issue for high torque riders right? If we spin for power instead of mashing, this would be less of an issue?
Apologies if these have been answered somewhere already, if so, can you be a good sport and point me to the right thread? I've done searches, but haven't found the exact answers I'm looking for yet...
LBS Mechanic is fitting Di2 to my Slice 5 today, he has had the same issues finding a drain hole that leads from the down tube, tried calling Cannondale but they haven't been very helpful. It looks like there isn't one; that means unless you drill the frame (and void warranty) it'll have to be an external battery. We're going to use the seat tube battery, but use shrink wrap to weatherproof it, then attach it externally using a bike pump mount and some small rubber shims. Its not the most aero option, but far from the ugliest, and clean too.
