The BySchulz Twist T10 can be mounted on a 1 1/8 steel ahead fork with an inner diameter of 25.4mm and is 10cm 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 uphill than downhill or for straight stretches. Intuitively, the differences are compensated with the arms and back. This is tiring and can lead to pain. This stem riser offers the solution by easily adjusting the height 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.
