Forged to master the complex demands of cutting-edge bicycle steering systems, this tapered headset bearing delivers absolute directional certainty and enduring alignment stability. Supplied as a full upper/lower service solution, it’s the critical resource for cyclists and mechanics insisting on microscopic steering accuracy, battle-tested resilience, and the instant recovery of silent, unwavering handling.
✅ Calibrated for Telepathic Steering Connection
The tapered raceway configuration expertly manages multidirectional forces from aggressive cornering and impacts. This precise taper ensures fork movement perfectly mirrors handlebar inputs, transforming steering actions into immediate, intuitive directional control with zero ambiguity.
✅ Definitive Alignment Through Hardened Metallurgy
Manufactured from vacuum-melted chrome steel, this component withstands permanent deformation under extreme loads. It sustains critical preload settings and sub-millimeter tolerances, providing an immovable foundation that locks frame and fork into designed steering behavior for thousands of miles.
✅ Impervious Sealing for Season-Spanning Reliability
Engineered contact seals form an absolute barrier against moisture, grime, and corrosive elements. This protection maintains lubricant integrity and raceway perfection, ensuring frictionless rotation and trouble-free performance through mud baths, coastal humidity, or freezing sleet.
✅ All-Components Kit for Flawless Reassembly
Designed as a total renewal system, this package contains every upper and lower element—pre-greased and dimensionally certified. Its exact-spec components enable a rapid, confidence-inspiring rebuild, restoring OEM-level smoothness and perfect neutral balance with guaranteed fit.
This restoration philosophy embodies a commitment to steering purity and lifelong trust. It annihilates wear-induced imprecision, creating a front end that reacts with instinctive sharpness, survives extreme environments, and delivers perpetually stable, connected, and silent control at every hand movement.
