Aerodynamic handlebar shaping does two things: it reduces the drag of the bar itself, and it positions your arms and body in a way that cuts your frontal area. The SES Aero IN-Route Road Bar from ENVE addresses both, using a wing-shaped profile through the tops and drops that's been validated in wind tunnel testing while placing your hands in a narrower, more tucked position at the hoods. The result works for road racers chasing marginal gains and short-course triathletes who want aero benefits without committing to a full TT setup.

The sizing convention here requires attention. ENVE lists each size with two measurements because the hood width differs from the drop width. A 35/40cm bar measures 35cm center-to-center at the hoods and 40cm at the drops, which puts your hands closer together when riding on the hoods where you spend most of your time. This narrower hood position is intentional, bringing your arms inward to reduce frontal area. The drops flare slightly wider for stability during sprints and descents when you need a broader platform.

IN-Route compatibility means this bar works with internally routed front ends that have become standard on modern frames. Cables and hoses run through the bar and into the stem rather than wrapping externally, cleaning up the cockpit aesthetically and removing potential sources of aerodynamic disturbance. The design accommodates both mechanical cables and electronic shifting wires, so you're not locked into a specific drivetrain type. Integrated bar end plugs finish the ends cleanly without separate pieces to lose or replace.... Read More
