The BySchulz Twist Pro SDS Ahead T15 stem riser is suitable for a 1 1/8 steel ahead fork with an inner diameter of 25.4mm and is 15cm 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 single ideal handlebar height. A different handlebar height is recommended for uphill than for downhill or straight stretches. 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 easy adjustment of the height as desired - even spontaneously, while on the go. It can be set for an upright or sporty position. Especially designed for sporty city and trekking cyclists and e-bikers.
