I've got a mix if di2 ultra and dura ace mechanical parts...

Just wired all the internal routing with zip ties etc. Question is the junction box...

The septets is blocked off allowing the junction box to be placed either in the downtime or chain stay, the chain stay is big enough to accommodate the junction box and is neatly tapered so a bit of wrap with bubble and it would sit in quite securely when the BB is installed.

Any reason not to do this and mount it in the downtime? Rattling is an obvious concern in the down tube as mine is massive on the Addict!
