⚡ At a Glance
- • Material & Finish: Aluminium alloy with plated colour options for corrosion resistance and a premium appearance
- • Best for: Riders upgrading or refreshing 1-1/8" road and mountain bike headsets

Aluminium alloy top cap plated in multiple colours fits 1-1/8" stems and forks. Package includes a headset star nut and bolt for installation.
Secure, precise preload - with included headset star nut and bolt
A star nut bites into the steerer tube while the bolt draws the top cap down, allowing controlled preload on the headset bearings before stem clamp torque is applied.
Proper preload sets headset bearings without play, producing crisp steering and stable handling after installation.
Corrosion-resistant appearance - thanks to plated aluminium alloy
Aluminium alloy receives a plated finish in several colours, creating a thin protective layer that resists surface corrosion and maintains visual appeal.
Plated colours keep the cockpit looking smart through wet weather and regular use.
Lightweight visual upgrade - with compact aluminium construction
Aluminium alloy allows a slim cap profile that remains strong while minimising added mass; the bolt sits flush to preserve a tidy look.
Adds noticeable visual polish without a meaningful weight penalty, ideal for riders who value aesthetics and function.
