About this item
- High-Quality Steel Build + Spacer Compatibility – Durable Headset Solution Crafted from premium steel, this 52mm headset bearing boasts rust resistance, high strength, and uniform hardness—paired with double shielding to block contaminants and retain lubricant. Its robust design works seamlessly with spacers (critical for adjusting headset height or fitting different bike fork steerer tubes): the bearing’s durability ensures long-term performance even when paired with spacers, preventing wear from the slight pressure between components. Together, they create a reliable, long-lasting front-end system for your bike.
- Precision Machining – Perfect Fit with Headsets & Spacers Fine machining gives the bearing a smooth surface and friction-free rotation, ensuring it aligns flawlessly with your bike’s headset—and with standard spacers. Unlike poorly machined bearings that cause misalignment with spacers (leading to rough steering), this bearing’s tight tolerances guarantee a snug, stable fit between the bearing, spacers, and fork steerer. The result? Smooth, responsive handling, as the bearing and spacers work in sync to maintain proper headset function.
- Dust/Water Sealing – Enhanced Protection with Spacer Support Equipped with a robust sealing ring, the bearing blocks dust and water to extend its lifespan—an advantage amplified by spacers. Spacers act as a secondary barrier: by filling gaps between the bearing and headset components, they reduce the chance of debris seeping into the bearing’s seals. This combined protection is ideal for off-road or wet-weather riding, where contaminants pose a greater risk to headset integrity.
- Pre-Greased Groove – Uninterrupted Rotation (Even with Spacers) The bearing features a grease-filled groove that prevents ball corrosion and enables free, smooth spinning—performance that remains consistent when paired with spacers. Unlike bearings that lose lubrication due to poor spacer alignment, this bearing’s precision fit with spacers avoids unnecessary friction that could displace grease. The pre-applied grease stays in place, ensuring the bearing and spacers operate quietly and efficiently for miles.
- Essential Replacement Accessory – 52mm Bearing + Spacers for Old Headsets This 52mm headset bearing is a must-have for replacing worn or damaged bike headset parts—and when paired with spacers, it becomes a complete upgrade solution. Whether you’re fixing a loose headset or upgrading your bike’s front end, the bearing (with compatible spacers) ensures proper fit and function. Spacers let you customize the headset height to match your riding style, while the bearing’s durability restores smooth steering—making this combo ideal for reviving old bikes or maintaining daily riders.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
