ENVE SES Aero Road Stem
ENVE SES Aero Road Stem, Once upon a time ENVE only offered one stem. It pulleddouble duty for both road and mountain duty and thanks to its lightness andtoughness afforded by its unidirectional carbon fiber construction it handled both quitewell. But as mountain bike geometries evolved the need for mountain-specificlengths and construction were needed. Around that same time ENVE begansponsoring World Tour Team Dimension Data and because at the highest level ofroad racing aero is everything the team asked ENVE if it could create a stemwith more drop to facilitate a long and low position on the bike the riderswere after and one with a slippery profile that when paired with its barsespecially the SES Aero or Aero TT bars would be a little more hidden from thewind. ENVE obliged and the result is the SES Aero Road Stem and if you're aroad racer or triathlete and are looking to optimize your position and improveyour bike's aerodynamics without sacrificing stiffness weight or ridequality this is the one for you. ENVE attacks the aero quandary on two fronts it'sadjustable both in length and angle which places the rider in an aggressivefaster position and the stem's profile is designed and shaped to better slicethrough the wind. It's important to note that this stem is intended for anegative drop only and cannot be flipped or reversed to a positive rise. Sincethe rider makes up the majority of aero drag a lower position is often muchmore meaningful reduction of drag than an aero helmet frameset or wheelsetand because the stem's angle adjustability allows you to dial in your handlebarheight without having to resort to additional headset spacers it allows forcleaner airflow at the front of the bike saving valuable watts. The roundedversus blunt faceplate combines with the hidden titanium bolts to furtherreduce the frontal area. The Aero Road Stem comes in 10mm increments between 100 and140mm and with 2 shims a fixed -12-degree angled shim tha...
