Aqua Proof Paste is the magic goop for installing bottom brackets and keeping them quiet. In the Kogel office, it's known as 'Shut up Grease'. Aqua Proof was developed by Morgan Blue from Belgium for the offshore industry. It's saltwater resistant, does not degrade over time, and is a long-time favorite of the UCI world tour mechanics. It works on any pressed or threaded surface to avoid corrosion. You'll find yourself using it for a lot more than just installing bottom brackets. The 5ml size is for a single bottom bracket installation, the 200ml jar will last a long time, even for professional use. - Recommended for all bottom-bracket installations - Also works on thread and headset installation - 5ml syringe is enough for a single installation - 200ml jar for shop use
