BICYCLE HEAD PARTS – Precision Steering, Smooth Rotation, and Long-Term Reliability

Engineered for Control, Stability, and Endurance

Designed for riders who demand responsive handling and consistent steering performance, these Bicycle Head Parts ensure flawless integration between the fork and frame. Whether used for mountain biking, road racing, or city commuting, they offer professional-grade stability, durability, and mechanical precision. Each component is carefully engineered to reduce friction, prevent play, and withstand the rigors of high-intensity riding.

Durable Construction and Precision Engineering

Crafted from high-strength aluminum alloy and hardened chromium steel, these head parts provide exceptional strength-to-weight balance and long-lasting resilience. The aluminum cups are CNC-machined for exact dimensional accuracy, ensuring a tight, secure fit with zero wobble.
The surface is anodized in matte black, offering corrosion resistance and a sleek, professional finish. Internal bearing races are precisely polished to minimize friction and enhance rotational smoothness, even under heavy load or wet conditions.
This combination of robust materials and meticulous craftsmanship ensures superior steering stability and a quiet, maintenance-friendly performance over thousands of kilometers.

Smooth Steering and Optimal Bearing Design

At the heart of these head parts are high-quality caged ball bearings that provide effortless steering and uniform load distribution. The precision-machined bearing races eliminate micro-movements and prevent wear, while the steel cages maintain ideal ball spacing for consistent rotation.
The result is buttery-smooth steering control, responsive feedback, and improved confidence when navigating tight corners or descending at high speeds. The integrated sealing system keeps dirt, dust, and moisture out, significantly extending bearing life and maintaining peak performance through all weather conditions.

Functional Components for Complete Integration

This full set includes every essential part for a reliable bicycle steering system:

• Top Cap & Bolt: Provides precise preload adjustment to eliminate bearing play and maintain structural alignment.

• Star Nut (Expander Nut): Anchors inside the steerer tube, securing the top bolt for stable tension control.

• Dust Cap & Compression Ring: Protects internal bearings from contaminants and maintains smooth steering alignment.

• Upper & Lower Bearing Cups: CNC-machined aluminum housings designed for perfect fit and rotational accuracy.

• Ball Bearing Retainers: Chromium steel bearings ensure minimal friction and high durability under load.

• Crown Race: Forms the critical interface between the fork crown and lower bearing, maintaining concentric stability.

Together, these components deliver a balanced combination of mechanical efficiency and user-friendly assembly, suitable for both professional mechanics and DIY enthusiasts.

Performance, Compatibility, and Efficiency

These Bicycle Head Parts are engineered for threadless steering systems and compatible with most 1-1/8 inch (28.6 mm) steerer tubes and 34 mm head tube inner diameters—the standard for modern mountain, road, and hybrid bicycles.
Their precisely matched bearing angles and low-tolerance fittings ensure no lateral play, providing a silent and secure ride. The design accommodates high-impact terrain and aggressive riding styles, maintaining alignment and rigidity even under demanding off-road conditions.

The efficient sealing and lubrication system reduce the need for frequent maintenance, allowing riders to enjoy long-lasting performance without constant adjustments.

Corrosion Resistance and All-Weather Durability

Engineered for year-round use, these head parts feature tight sealing and anti-rust treatment on all critical steel components. The anodized aluminum surface resists oxidation and scratches, ensuring consistent appearance and function over time. Even in rain, mud, or dust, the integrated seals protect the internal bearings from contamination—guaranteeing long-term smoothness and stability.

Streamlined Aesthetics and Minimalist Design

These head parts feature a refined matte black finish that complements any frame color or component setup. Their clean, compact profile integrates seamlessly with modern bike designs, providing both functional performance and visual harmony. Subtle machining lines and precision edges emphasize craftsmanship and attention to detail, reflecting the engineering excellence behind every component.
