What they say: A chain lube from Park Tool, the leader in bicycle maintenance products. Uses PTFE and a proprietary blend of oils.
What we say: It’s sort of a surprise, given Park Tool’s huge range of workshop tools and maintenance equipment, that a chain lube hasn’t been offered sooner. Made from a blend of synthetic oils, Park Tool has covered all the obvious bases, but by including PTFE (which is used in Teflon) it further reduces friction between moving parts. There are other compounds in the mix, too, that protect parts against rust and corrosion. It comes with a locking screw-top lid in a handy 118 ml-sized bottle.
