Di2 for Supersix

[KH1]

Does anyone know what external Di2 upgrade kit suits a Large Supersix frame?
There are 3 options small medium and large.
You'd think it would be fairly straight forward but just in case there are other considerations I thought I'd ask the question before I buy.
Thanks

I have a large on my 56cm, just to be sure, the extra cable is folded up nicely under the BB junction box.
You will however, not be able to screw this junction box into the BB like you are supposed to. As the BB is HUGE, the cable to the FD is too short, I needed to push the junction box way back on the BB to get the FD cable to reach. The junction box is held onto my frame with Selleys All Clear sealant.

Thanks for that.
Are you saying the FD cable was too short even on the large kit?

Yep.
