Like other Zipp stuff

Familiarity:
I've put it through the wringer

Light, stiff, and tasteful graphics like other Zipp cockpit components. The quality, weight, etc. are on par with prior ServiceCourse SL stems so from what I can tell this is just a design refresh. I have the -17 degree and just got the -6 degree. The -17 version makes your stem basically flat to the ground but the sharp angle looked kinda funny. The -6 degree allowed me to drop down a spacer.
