For those who seek a wing-style alloy road handlebar with compact dimensions, Di2 compatibility and reasonable weight, the WCS Streem III from Ritchey is perfect option. The immediately distinguishing feature of the WCS Streem III is the aero top section. This aero section is 38mm deep and 22.5mm tall profile and offers a slightly ovalized top surface that is both aerodynamic and comfortable for those more upright riding positions. The anatomic drops have been optimized with large sections and better angles for most riders. The drop itself measures 128mm in all sizes. The reach is 73mm in all sizes, perfect for today's levers. The gentle subtle back sweep is less noticeable, but helps keep your wrists in a more anatomically correct position when your hands are riding on top of the bar. This ends of the bar have no outward flare.

A recessed channel under the bar keeps housing under control, and allows you to keep tape off much of the aero top section. The WCS Streem III is Di2 eTube wiring and the bar-end style EW-RS910 junction box compatible. Ritchey uses a non-slip grit on the stem mounting zone to eliminate slippage and assist the mechanic with not over-torquing the bolts. Ritchey bars are measured center to center (c-c) at the shifter mount section (not at the end of the drops).
