The OneUp E-Bar features internal routing for Shimano STEPS switch units, Bosch LED Remote, and all other switch units with a connector diameter of less than 6.5mm.
The wire port diameter in the bar is 6.5mm and the minimum switch wire length required to internally route is 650mm.
Specialized, Bosch Purion or Rocky Mountain remote power mode controllers cannot be internally routed through the Carbon E-Bar.
If you have a switch with a removable wire (EP8, E8000, E7000) you can install a 650mm or longer Shimano EW-SD50 (1st gen EP8, E8000 & current E7000) wire or the EW-SD300 (2nd Gen EP8 & E8000) wire.
The Orbea Rise does not have a handlebar-mounted display unit as it connects to your smartphone. It has the EW-EN100 junction and removable EW-SD50 wire.
If you don’t have a removable wire on your switch, you need to buy a new switch with a removable wire (SW-E7000-L) with a wire length of at least 700mm.
Or you you can add the EW-JC200 2 port junction and an EW-SD50 extension wire
