Park Tool Synthetic CL1 Chain Lubricant

This is a 120ml/ 4oz bottle of synthetic lubricant, with PTFE, that operates effectively in wet or dry conditions.
It is not only suitable for chains, but can also be used on cables, spoke nipples, and derailleur and brake pivots.
It penetrates components and displaces moisture, thereby reducing friction and prolonging component life, while protecting parts from rust and corrosion.
