I am building up a new Gravel bike indwell be running Di2 with Hydraulic brakes and using the Shimano Bar end charge port. I would like to run all the cables inside the bars if possible (at least all the Di2 cables anyway), but not sure what bars support internal cables.

Ideally I would like Aluminium bars, I see a lot of carbon bars with internal routing but can’t see any Aluminium ones.

Anyone got any experience/bars they have used?
