No, the alu bars don't have proper internal routing. This is the only pair of bars in the pro range "designed for Di2 internal routing" other than the Aero versions of the Vibe, that ACTUALLY internally route both brake and Di2 so you can bar end junction and do away with the under-stem-sling.
I've been using 3T Tornova LTD, which lasted 2 rides as they're made of cheese and Deda SuperZero Alloy, which have actually been fucking amazing, albeit I hate their shape. Otherwise, apart from other 3T variants (all made of the same cheese) and a few outrageously priced super brands (Schmolke, ENVE, etc - albeit all Aero variants with stupidly large flat tops) I haven't found a single normally shaped compact drop handlebar with FULL internal routing other than the Pro Vibe Carbon Monococque.
And I've been looking for almost a year.
but do they have the internal routing?
how have you been doing the cabling with the bar end charger with your other bars?
