Lightweight aluminium alloy spacers supplied in seven pieces for 1-1/8 inch steerer. Precision diamond-disc machining and anodised finish improve fit and corrosion resistance.


Fine-tune handlebar height - with multiple spacer sizes

Set includes one 2 mm, one 3 mm, one 5 mm and four 10 mm spacers, allowing millimetre-level changes to headset stack height.

Accurate incremental adjustments let riders dial in posture and reach without cutting the steerer or guessing at fit.

Secure steering - with precision-cut aluminium alloy

Quality aluminium alloy is machined on a diamond disc to consistent outer diameters and tolerances for even clamping pressure.

Reduced headset play and a firmer front end make steering more predictable on busy roads and rough trails.

Corrosion-resistant and lightweight - with anodised finish

Black anodised surface provides a colourfast finish and corrosion protection while the full seven-piece set weighs around 35 g.

Durable aesthetics and minimal weight add no noticeable bulk to the bike while resisting everyday wear.
