My bars (drop) have HB tape, either Fizak or doubled cloth, aero brake levers (no brifters), the gravel bike has in-line CX style levers on the tops and another SunTour Command shifters and a simple cadence computer (my trainer bike). All have bar plugs. The bike being ridden may have a small Serfas light on it. I like clean, simple handlebar setps.
