TF2 Plus Dry Lubricant with Teflon Surface Protector and TF2 Dry Wax Chain Wax + Krytox
It was unfortunate that being sent a couple of dry lubes to test coincided with a run of pretty poor weather, however I have now had some time to properly put them through their paces. The long and short of it is, if I were spending my own cash, the wax based lube is the one I would go for from now on.
Both were equally easy to apply - a notable improvement for the wax based model over similar offerings from rival brands. As another reviewer has already mentioned, the consistency and colour of the Krytox wax lube makes it dramatically easier to ensure a sufficient dose. Both, as was to be expected, rinsed off in the rain (read flash flood). However, while the control over other variables in testing was non-existent, a wet ride after a few days running the Teflon based model was the only occasion after which I discovered actual rust on my drivetrain.
Both lubes resulted in beautifully smooth and silent running, so there is one other deciding factor for me. The wax-based lube, according to the lack of symbols on the bottle, has no hazardous ingredients. So, considering weight aside (I'm sure the Teflon stuff is lighter) it is surely a no brainer?
