Looking at the video, the builder uses the Deda Superbox DCR, which allows full internal or semi-internal routing. That's pretty cool. There'a also the FSA SMR stem that looks nice. I think the challenge I have with such stems is that I've always used +6 degree stems (mounted upwards.) I don't think I've ever ridden a stem that's mounted in a downward angle. I wonder what effect that would have? The Deda and FAS are -6 degrees, which would deviate about 12-14 mm downward from what I'm used to (about .5 inch.) No biggie, or a potential no-go?
