The ENVE Aero Road Stem is an aerodynamically honed stem now available compatible with ENVE In-Route internal routing system.
The Aero Road Riser Stem was designed to achieve a rider's ideal position without the need of excessive spacers. This stem can provide 43.5-49mm of stack and does so by increasing the stack height of the stem's steerer clamp and a positive stem angle.

I recently built up a couple bicycles with full internal routing using the Coefficient RR handlebars. There were limited internally routed stems available. I've had several sets of ENVE wheels and forks in the past and have always thought highly of their designs quality control.
PROS: Out of the box this stem looks great! The -7 option worked for one bike while the +12 was a better fit for the other bike. Both stems are comparable in design and filament. They also look great on the bike. The routing design is well thought out and worked very well with the Coefficient bars. I did like how ENVE separated the hose routing into two individual openings. Their tolerances were very tight but easily accommodate one brake cable. Adding a second shift cable would be tight but doable.
CONS: I was very diligent to maintain the same bolt configuration when disassembling these stems. In the build process one bolt was out of sequence and I found it wanted to cross thread easily. You will want to put each bolt back in the factory location when re-installing. Not a difficult task but a touch annoying. The spacers are cheap plastic and look that way. At this price point a higher quality material would be welcomed.
It will be interesting to see if this design holds up as more manufacturers join the internal routing game.
