ACF-50 Anti-Corrosion Formula/Lubricant review£12.00

Products developed for use in the aerospace industry often translate very well to cycling and this is no exception. This is not a PTFE-based water displacer, but is designed to form an atmospheric seal against the elements.

Products developed for use in the aerospace industry often translate very well to cycling and this is no exception. This is not a PTFE-based water displacer, rather it is designed to form an atmospheric seal against the elements which, it claims, remains effective for 12 months and kills corrosion on contact.

I applied a light application to a pair of SPD cleats sporting some surface corrosion. From the nozzle, ACF-50 is pinkish purple, but within a few minutes the mixture settles to a neutral hue and I was amazed to find the dirty brown corrosion on the cleats had apparently neutralised to a matt black.

While far thicker in viscosity than water displacement sprays, it lends itself better to corrosion prevention than lubrication, so isn't really a chain lube. But I have every confidence that, reapplied twice yearly, it should minimise chances of internal corrosion in frames, trailers and racks, and eliminate the need to drill out corroded SPD shoe fittings - even on bikes living in coastal regions.

Although £12 for a 369g aerosol might not seem particularly cheap, a little seems to go a long way.
