TriFlow was the original made for bicycle chain lube and it had Dupont Teflon in it and it works pretty good. But there are better lubes on the market, such as Chain L. Chain L is superior to any lube I've ever used. The only lube I used previous to Chain L that I liked was Finish Line Dry...what was in that? Teflon, the same as TriFlow and as Dupont Teflon at Lowes. Teflon does work, wax based lubes do not, Chain L doesn't review it's ingredients but it probably has some Teflon mixed into the mineral oil base and extreme pressure lubricant...whatever that is.
