CeramicSpeed 15267 Bearing

You need to verify the dimensions of your current headset bearing. This specific model features a 15mm inner diameter, 26mm outer diameter, and 7mm height. If your current bearing matches these exact measurements, it is compatible.

The coating applied to the races significantly increases surface hardness and corrosion resistance. This creates a smoother, more durable surface for the ceramic balls to roll on, which helps the bearing last longer in harsh riding conditions.

Yes, they are designed to handle demanding environments. The combination of non-contact seals and a reinforced polyamide cage helps keep contaminants out while maintaining smooth rotation, making them reliable for both road and off-road use.

CeramicSpeed bearings are designed to perform well with standard high-quality bearing grease. However, because the seals are non-contact, you should ensure you are using a grease appropriate for your specific riding conditions to maintain the longevity of the components.

Ceramic balls, specifically Grade 3 Silicon Nitride, are harder, lighter, and smoother than steel. This results in lower friction and improved power transfer, while also being less prone to corrosion.
