The CeramicSpeed SLT bearing (Solid Lubrication Technology) for headsets: OHD (Optimized Headset Design) features a unique combination of an oil-encapsulated full polymer and stainless steel materials, resulting in a self-lubricating, corrosion-resistant, and maintenance-free bearing. The micropores in the otherwise solid polymer evenly distribute just enough oil to keep the bearing well-lubricated, while also containing enough oil to be self-lubricating throughout the entire lifespan of the bearing—even when subjected to the harshest conditions. The CeramicSpeed SLT OHD bearing is designed, developed, and handcrafted in Denmark and comes with a lifetime warranty.
