Is there any downside to wiring everything in one long line in Di2?
BB junction > left Shifter>Right Shifter> 3 port junction box.
I'm looking at having a TT shifters that are easily taken on and off the bike, so I'm hoping the above setup would leave 2 free ports on the junction box for the TT shifters to be added into.
I guess is means if one wire is disconnected or broken the whole system is useless which is not ideal.
