The BySchulz Twist T6 can be mounted on a 1 1/8 aluminium ahead fork with an inner diameter of 24.6mm and is 6cm height adjustable. 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. 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 riding 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, on the go. It can be set upright or sportily. Specifically designed for sporty city and trekking cyclists and e-bikers.
