A bike headset top cap that secures the headset and trims unnecessary grams for a neater, lighter cockpit. Riders who want tidy aesthetics and reliable fastening will appreciate the durable aluminium construction and precise machining of FIFTY-FIFTY Bike Headset Top Cap. Is fitting a lightweight, waterproof top cap the right upgrade for a bike with a 1 1/8-inch stem and forks?
⚡ At a Glance
- • Build Material: Aluminium alloy construction, described as durable, ultra-light, waterproof and anti-rust
- • Best for: Cyclists who value a low-weight cockpit and tasteful visual accents
- • Not ideal for: Riders with stems or forks sized other than 1 1/8" (28.6mm)
Aluminium alloy cap is CNC machined and developed with FEA to reduce excess weight. Compatible with 1 1/8-inch stems and supplied with an M6 fixing steel bolt for secure attachment.
Secure Headset Preload – with an M6 fixing steel bolt
An M6 fixing steel bolt is included and intended for standard headset preload. The bolt pairs with the top cap to clamp the steerer reliably when assembled.
Secure fastening keeps headset adjustment stable during rides, making maintenance straightforward. Quick assembly and disassembly suit workshop or trail-side adjustments.
Reduced Weight without Compromising Strength – thanks to CNC machining and FEA optimisation
CNC machining removes surplus material precisely while finite element analysis guided development to preserve structural integrity. Machining tolerances lower unnecessary mass without introducing weak points.
Lower rotating and overall bike weight improves responsiveness and feels marginally livelier on climbs. Performance-focused riders gain small but tangible weight savings at the cockpit.
Weatherproof Durability – with aluminium alloy and anti-rust finish
Aluminium alloy construction resists corrosion and the finish is described as waterproof and anti-rust, reducing susceptibility to moisture. Surface treatments help maintain appearance and performance in wet conditions.
Reliable corrosion resistance reduces maintenance and keeps the headset area looking neat through seasons. Suitable for regular wet-weather riding without frequent replacement.
