Delta Cycle Bike Stem Raiser

This component provides a maximum height extension of 4.6 inches (116.84 mm). This range is usually sufficient to significantly alter your riding geometry for a more upright, comfortable position.

Installation is straightforward and typically requires only basic tools like a hex key set. If you are comfortable adjusting your own stem and headset, you should be able to install this without professional help, though you must ensure all bolts are torqued correctly to manufacturer specifications.
