Alloy Threaded Fork Stem Riser

A precision-engineered aluminum alloy adapter built exclusively for bikes with threaded fork steerer tubes. With a fixed 160mm length, it lifts the handlebar assembly to improve upper-body comfort and steering responsiveness. Its polished anodized exterior resists environmental wear while complementing both modern retro and heritage-inspired builds. The internal expansion mechanism creates uniform radial pressure within the quill stem upon tightening — ensuring zero rotation or vertical play. Supplied as one complete unit, it integrates seamlessly into existing threaded headset systems on mountain, road, and hybrid bicycles.
