The BySchulz Twist T6 can be mounted on a 1 1/8 inch steel A-head fork with an inner diameter of 25.4mm and is 6cm height adjustable. The fork allows for precise, tool-free height adjustment of the handlebar in seconds using the quick-release lever. The handlebar can also be rotated 90 degrees to the left or right. More about the function of a stem riser The height of the handlebars is crucial for riding comfort. However, there is no ideal handlebar height. A different handlebar height is recommended for uphill riding than for downhill or straight sections. Intuitively, these differences are compensated with the arms and back. This is tiring and can lead to pain. This stem riser offers a 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.
