I tried to google and also search this forum but don´t find stems with internal cable routing. What I am looking for is a standard stem that routes the cables (eTap as well as rear-brake) directly from the basebar to the back of the stem. A center cable-stop for the TriRig front-brake would be another bonus...

PD Aeria Ultimate stem is design-wise perfect but too heavy for my taste (especially as it is unlikely I will make use of the matching hydration).

Any ideas?
