The fork allows for precise, tool-free height adjustment of the handlebars in seconds using the quick-release lever. The handlebars can also be rotated 90 degrees to the left or right, and the angle can be adjusted. More about the function of a stem riser The height of the handlebars determines riding comfort. However, there is no ideal handlebar height. A different handlebar height is recommended for uphill than for downhill or flat sections. Intuitively, these differences are compensated for with the arms and back. This is tiring and can lead to pain. This stem riser offers the solution by allowing the height to be easily adjusted as desired – even spontaneously, while on the go. It can be set upright or sporty. Especially designed for sporty city and trekking cyclists and e-bikers.
