More Comfortable Riding Position - Thanks to Adjustable Height Up to 85mm
An extender sleeve slides over a 1-1/8" (28.6mm) threadless steerer and accepts four spacers (1×5mm and 3×10mm) to change effective stem height in incremental steps. Tightening the clamp secures the stem at the chosen stack height.
Customise posture in small, repeatable steps to reduce back and shoulder strain for commuting or longer off-road rides.
Strong yet Lightweight Construction - With Forged 6061 Aluminium Alloy
Forged 6061 aluminium alloy forms the extender, delivering a high strength-to-weight ratio and consistent structural integrity under normal riding loads. The forging process increases material toughness compared with cast alternatives.
Durable build minimises flex during climbs and sprints while keeping added mass low, preserving handling and responsiveness.

The package contains four spacers (one 5mm and three 10mm) plus two hex keys, allowing stem height to be altered by swapping spacers and re-clamping. No extra parts are required for standard adjustments.
