Enve SES Aero Road Stem has adjustable angle and reach

Published May 24, 2018

OGDEN, Utah (BRAIN) — Enve Composites’ new SES Aero Road Stem is designed to enable riders to achieve their optimum position and reduce drag through aero shaping while still preserving handlebar options.

The stem was developed with input from Team Dimension Data, including sprinter Mark Cavendish and lead-out man Mark Renshaw. It features a low-profile clamp and is adjustable via two steerer clamp shims to tune the stem angle and, hence, bar height. Stem length can also be adjusted plus or minus 2.5 millimeters. An integrated computer mount was designed in collaboration with K-Edge.

The aerodynamic design was carried out in computational fluid dynamics (CFD) by Smart Aero Technology and then honed at the Mercedes AMG Petronas F1 wind tunnel in Brackley, England. Wind tunnel testing of the stem revealed a small but valuable 0.6W average gain through a full sweep of wind angles at 40 kph compared with the classic Road Stem, Enve stated, and the SES Aero Road Handlebar saves an additional 5W.

“SES component development is built on the concept of ‘Fit is Fast’, meaning a rider is only as fast as their body position on the bike allows them to be,” said Jake Pantone, Enve’s VP of product and consumer experience. “While each SES product is aerodynamic by design, it is what the product, in this case the stem, allows the rider to do with their position that ultimately helps the rider go faster.”

The SES Aero Road Stem is available in lengths from 100 to 140 millimeters, at $300 MSRP.
