White Lightning has developed Crystal Grease for cyclists and mechanics who are simply unwilling to compromise on performance or ecology. An aluminium based thickening system makes Crystal Grease 100% water proof, perfect for wet weather road rides or stream crossings on a mountain bike. Premium hydro-treated base oils deliver smooth bearing lubrication and long-lasting durability. Crystal Grease will not attack seals or carbon fibre. Crystal will not stain painted surfaces. Crystal Grease allows mechanics to visually identify wear and contaminate particles.
