The Ceramicspeed SLT bearing for headsets.OHD (optimized headset design), features a unique combination of an oil-encapsulated solid plastic polymer and stainless-steel materials which results 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 sufficient oil for it to be self-lubricating over the lifespan of the bearing even when ridden in the harshest of conditions.The ceramicspeed SLT OHD bearing is designed, developed, and hand-built in Denmark and comes with a lifetime warranty.
