Not all that long ago, when riders thought 3-In-One and WD40 were acceptable bike lubes, the iconic Phil Wood introduced a superior bike-specific chain lube. And he started a revolution in bicycle care and maintenance. If you’re old enough to remember this then Phil’s may still be your first choice. 50 years later and it’s still a darn good bike lube! If you’re a dyed-in-the-wool biker and haven’t used Phil Tenacious then there’s a gap in your schooling. It’s very good stuff, and it’s still priced like it’s 1969. :>D
