Aero Road Stem

Description

What It Is
An aerodynamically honed stem with adjustable length and angle to optimize your position. Linking handlebar to fork, the stem was developed with Team Dimension Data for the refined ride response and control needed in a critical area of the bike. This stem is intended for negative drop only and cannot be flipped or reversed in a positive rise.

Why We Made It
The rider makes up 80-90% of total aero drag, so refining your position can produce some of the biggest gains of all. Further, the shape of the stem, plus the ability to eliminate headset spacers, allows for cleaner airflow at the front of the bike, producing valuable drag savings. Created in conjunction with Team Dimension Data, the stem delivers the confident and responsive ride feel desired by the best riders in the world.

Who’s It For
Racers, triathletes, and performance-focused riders looking to optimize their position and improve overall aerodynamics, while maintaining the stiffness and comfort needed for speed.

Full Details
Our approach to aerodynamics has always been to find the best solution for the complete system of the bike and rider, because we understand that there is more to aerodynamic performance than a low drag figure in the wind tunnel. This approach can be seen in our wheels, where we target stability alongside drag reduction to make you as fast as possible on the road in real conditions, where it counts. It can also be seen in our pioneering SES Aero Road Handlebar, which delivers a speed boost through rider positioning as well as its shape. The SES Aero Road Stem is the natural partner to that handlebar, using the same parallel design considerations. First, we developed a shape with reduced frontal area, smoother airflow, and lower drag. Next, we designed in beautifully simple methods for adjusting the angle and fine tuning the length. The result is a lightweight stem that fits any of our handlebars and makes you faster.

    Adjustability

    Among the many great features of this stem, my favorite has to be the adjustability. Not only do you have multiple angle options, but you also have length adjustability (+/- 2.5mm with the -12 degree shim). I actually messed up and overestimated the length of stem that I needed when I first ordered but ended up using the shim to bring it back that 2.5mm and it felt dialed! Also, I have this stem paired with the aero bar and not only do they look super stealth together, but they also greatly improve ride quality.

    Not much to say other than this stem is the most adjustable, attractive stem on the market. All stems should include this level of design and integration. Well done ENVE.

    Great pairing with the ENVE Aerobars, this aero-stem is pretty rad! It’s all carbon and weighs pretty much nothing, but is still stiff. It essentially only has negative angles so make sure you still have a little more steering tube in case you need it. It comes with a shim to adjust the angle, ranging from -7 degrees to -17degrees. I have mine at -12, but with a few cm under the stem.

    Looking for a racier set up? Or just want to look like a racer? This stem is for you!

    Super sleek and adjustable

    Once I got my second aero handlebars from Enve I went full out and got this stem as well. It’s super smooth in looks, surely good for the aero optimizers amongst us, but for me the selling point above other aero options is the adjustability. After all the body position matters most but often you need to try a new position for many rides till you are sure that it will work out for long. This one delivers!
    What I would love is to have one or two optional other inserts as extra spare parts to play even more with angles and lengths.
