Help installing Di2 on Speedmax CF

Triathlon Forum

I have a 2018 Speedmax CF 7.0 that I am wanting to convert to Di2.

I understand the junction box sits in the bento box on the top tube, and it looks like the battery sits in the seatpost, but I’m not sure how to get the JC41 junction box into the frame. When I have done this previously on other road (not TT) bikes there has been a way to access the frame near the BB and the JC41 junction box is stored there, but I can’t see an obvious way to get into the BB on the Speedmax CF? Is the JC41 junction box maybe stored somewhere else?

Can anyone shed any light on this? Thanks!

I don’t have experience with the speedmax, but I have put di2 on some road and tt bikes. I have removed the bb completely to get the j box in there and get all the cables run on bikes that were not made with an access point. May want to wrap some foam around it if you think it’ll rattle and bother you.

Great thanks. I’ll check that option out.
