Precise Height Changes - with five distinct spacer thicknesses

Designed for 1 1/8 inch steerers, the set includes spacers in 3mm, 5mm, 10mm, 15mm and 20mm. Stacking or removing individual spacers alters headset stack height by exact millimetre steps.

Make measured handlebar height adjustments without cutting the steerer, so trial-and-error setup becomes quick and reversible.

Durable yet Lightweight - with alloy construction

Alloy material delivers a favourable strength-to-weight ratio, keeping mass low while maintaining structural integrity under clamp pressure. User feedback confirms a well made, durable feel and a lightweight profile.

Reduce added weight to preserve bike handling while relying on durable spacers that withstand routine use.

Neat, Low-Profile Finish - with black alloy appearance

Black finish creates a consistent look across the headset stack and helps hide minor scuffs. The finish complements a wide range of cockpit colours without drawing attention.

Maintain a tidy cockpit aesthetic while ensuring spacers blend in with most bikes, from commuter builds to sporty rigs.
