The BySchulz Twist T8 can be mounted on a 1 1/8 steel ahead fork with an inner diameter of 25.4mm and is 8cm 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: Handlebar height is crucial for riding comfort. However, there is no ideal handlebar height. A different handlebar height is recommended for uphill than for downhill or for straight sections. Intuitively, differences are compensated 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. Especially designed for sporty city and trekking cyclists and e-bikers.
