SL-70 Aero

Brand: Zipp

The SL-70 Aero is a unidirectional carbon road drop bar with a distinctive wing-shaped airfoil top developed with the same CFD tools Zipp uses for its wheels, claimed to cut drag to about 0.11 N versus 0.74 N for a round tube (roughly 6.4 W of savings). It uses a compact short-reach bend with 70 mm reach and 128 mm drop, and routes cables internally via Zipp's Rapid Routing. UCI-legal, it is distinct from the SL-70 Ergo and the gravel-oriented SL-70 XPLR, and was later succeeded by the Service Course and SL-70 Ergo line.
