ENVE SES Aero One-Piece Handlebar

The ENVE SES Aero One-Piece Handlebar is an integrated road cockpit that merges bar and stem into a single piece. It is built around one idea: the rider's body causes most of the drag in the bike-and-rider system, so ENVE shaped the bar to reduce frontal area. The SES Aero road bar first appeared in 2016, and this version carries a new drop shape that ENVE says takes inspiration from its SES AR bar.

Aero shaping and fit

The drops use an airfoil profile, which ENVE designed to cut drag. Optional shaped pads add cross-section to the drops for further drag reduction, and ENVE designed them to dampen vibration as well. The bar is optimized for use with ENVE Race Bar Tape and pads. Reach is 76mm, drop is 128mm, and the stem angle is -7 degrees.

You choose from six stem lengths, 90mm through 140mm, and three bar widths: 37/40cm, 39/42cm, and 41/44cm. Weight runs from 335 to 355g depending on the stem length and width you pick. The bar is IN-Route compatible, so brake and shift lines can route internally on frames designed for it.

It suits riders who want a clean, low-drag front end on a race or aero road bike and need to dial in stem length and bar width separately.
