This is a synthetic lubricating oil specially designed for Bones skate bearings. Designed with the aim of reducing drag as much as possible and to process a durable micro film layer on the balls of the bearings, so that wear is prevented.
Skate tests have shown that the Bones Speed Cream works better than oils based on Teflon when it comes to inline skating and the specific conditions you have to deal with as a skater, such as dust, side pressure, rough ground.
