Forged Aluminium Stem Extender

Built from forged aluminium alloy for superior strength-to-weight ratio, this stem extender offers lasting reliability, zero rust formation and resistance to bending or cracking under load. It ships with five 10mm spacers, enabling cumulative height extension up to 100mm. Riders adjust height simply by adding or removing spacers—allowing tailored fit for varying torso length, flexibility and preferred riding posture. Compatible with all bicycles using a 1-1/8 inch (28.6mm) threadless steerer tube—including mountain bikes, road bikes and gravel or fitness models. Installation follows standard OEM procedures using existing stem hardware.
