RE: recommended lube for axles/cams?
WD40 is BAD BAD BAD....I couldn' t have said that better myself...
I like to use either white lithium (as Jeff mentioned) or I also use Tri-Flow which is Teflon based or there' s also a product called Tetra Bow Lube that works real well.
I use Tetra on customers bows when I work on at my buddies shop.
