The King of Lubes is the Rock "N" Roll lubrication. The Gold is formulated to work on all bicycles (road, mountain, cross, you name it). It doesn't gunk up the chain and simply works. Our pro mechanics swear by this lube as do our customers who've tried it. Watch your chain, it doesn't turn black like it used to. This lube cleans and lubes all in one, it's easy to use and doesn't have to be used nearly as often as most of the other traditional oils. This is one of many ideas for gifts found on our shelves this holiday season.
