The BySchulz Twist Pro SDS Ahead T8 stem riser is suitable for a 1 1/8 inch 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, and the angle can be adjusted. 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 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 a solution by allowing the height to be easily adjusted as desired – even spontaneously, on the go. It can be set for an upright or sporty riding position. Specifically designed for sporty city and trekking cyclists and e-bikers.
