We didn’t set out to make the lightest stem in the world. No, we wanted to make the lightest stem in the world that could withstand years of rigorous abuse on racecourses like Paris-Roubaix. In fact, the EC90 SL stem is so strong it will hold up just fine to cyclocross and XC mountain bike racing. We were able to whittle weight down to just more than 100 grams (in the 100-millimeter length) thanks to our exclusive TaperWall™ technology and a touch of titanium hardware. Because we wanted to be sure the EC90 SL would never leave you wanting more when it came to handling or durability, we used our proprietary Distributed Stress Technology and Top Lock faceplate to maximize the handlebar/stem interface.
