The BySchulz Twist Pro SDS Ahead T6 stem riser is suitable for a 1 1/8 inch steel ahead fork with an inner diameter of 25.4mm and is 6cm height adjustable. The fork allows for precise, tool-free handlebar height adjustment in seconds using the quick-release lever. The handlebar 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 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 a solution by allowing the height to be easily adjusted as desired – even spontaneously, while 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.
