Hello,
For my Roadbike with which I want to ride long endurance trips, I put on some Quick-Release Aerobars from Redshift. 22mm OD 19mm ID
Since I have the SRAM Red and wired Blips, I designed some Endcaps for the Aerobars to be able to shift while being in the aerobars.
To make it removable I cut the Blip cable, soldered some XT30 connectors to it and left the connector almost fully covered underneath the bartape. I made some dead plugs to keep it dry from rain and stuff when the aerobars are not mounted.
Inside the Aerobars the wire with the XT30 can be hidden and led through a small opening to connect to the connector on the handlebars.
I think this solution is quite neat and easy to make on your own.
I will put a little more shrink tube to make it fully waterproof.
