Why We Make ThisYou wouldn&&';;t make your own pasta from scratch and then pour jarred sauce on it. So yeah, the kind of people who make their own bearings also formulate their own lubricants. It&&';;s kinda who we are.Why You Want ItChris King Silver Grease is a nano-particle lubricant optimized for hub and bottom bracket bearings. A nano lubricant is one that is lubricious (a real word) at its molecular level. With Silver Grease, we struck a balance between providing the lowest possible drag and still providing excellent weather resistance. It&&';;s compatible with both our steel and ceramic bearings.Available in two sizes: - 200g (8 fl. oz.)- 30g (1.2 fl. oz.)
