Aluminum Alloy Concealed Stem Extender CNC-Machined Cycle Stem Riser Extender Locking Rings Black

This stem extender is made from aluminum alloy with a CNC-machined finish. It combines a black cylindrical upper body with a silver textured lower expansion section for an exact, refined look. Designed as a stem extender, it raises the handlebar stem position by fitting into the fork steerer area and helping create a more comfortable riding setup. This concealed stem riser uses an internal expansion structure with locking rings, keeping the cycle stem riser extender streamlined while securing it in place. It is intended for a 28.6 mm fork steerer/stem mount area and for fork steerer inner diameters greater than 23 mm, built around specific fit requirements. By adding height and adjusting reach, the concealed stem riser can support a more upright riding posture and improve everyday riding comfort on the bike.
