Safer Steering – with a precise headset fit
The cap's 31.8 millimetre outer diameter is made to match standard 28.6 millimetre head tube stems, clamping the fork tubes securely to the headset. Correct installation limits play in the steering assembly and helps prevent the top of the headset from loosening during rides.
A properly fitted top cap promotes steadier handling and clearer steering feedback, increasing confidence on rougher terrain and during brisk cornering.
Lightweight Durability – thanks to aluminium alloy construction
Aluminium alloy combines high strength with low weight, while the oxidised surface treatment improves resistance to abrasion. A stainless steel bolt complements the cap by providing a secure fastening point resistant to corrosion.
A durable yet light headset cover keeps the front end of the bike easy to manage and reduces the need for frequent replacements or touch-ups.
Instant Visual Upgrade – with an oxidised blue finish
Surface oxidation adds stable colouration and a harder exterior layer that resists wear from exposure and handling. Design focuses on a tidy appearance that integrates with most mountain and road bike cockpits.
A neat, coloured cap refreshes the bike's look while matching other components, allowing cyclists to personalise their machine without major modifications.
