HighSix OS Handlebar Stem

Adjust your stem the way you want!
The HighSix is specifically designed to create maximum freedom to adjust your handlebar stem exactly the way you want it. The maximum 40 degrees angle brings your upper body up and releases the pressure of your lower back. Using the HighSix the other way around, you can create a maximum of 40 degrees downwards for a more aerodynamic position. The ideal handlebar stem for a higher as well as a lower riding position. Compatible with electrical gears.
