Easton EC90 SL 80mm 31.8 +/- 10 degree Carbon Stem

Easton didn’t set out to make the lightest stem in the world. No, they 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.
