Prolink, Prolink, Prolink.............Prolink. And please disregard any suggestions from above posters who have not tried Prolink, because they do not know what they are missing.

"It's not a lubricant, it's a metal treatment"!

Sounds like contrived marketing jargon but it works so damn well I don't care.

Note: If you are running a chainguide with plastic components, DO NOT use Prolink. Or Boeshield T-9. This comes from the friendly folks at E-13. And would also lead me to believe that Boeshield is as good as Prolink.
