This is an easy one. Tri-Flow is simply one of the greatest things ever. I keep both a drip bottle, and an aerosol in my workshop all of the time.
Whenever I true a wheel I lube the nipples first, when I've got STI or Rapidfire shifter problems I shoot some Tri-Flow in there and it gets worked out. They don't cal it "mechanic in a can" for nothing. Shit fixes everything, stubborn derailleur pulleys, squeeky door hinges, you can use it to penetrate rusted parts. It's just good for everything.
There was a time in the late 90's when dry lubes were the hot thing. For at least a year I had a squeeky chain due to the dry lube flaking off all in the concept of having a "cleaner" drivetrain. Well one day I had no dry lube, so I used a can of Tri-Flow. Holy shit was my mind blown. My bike had gone silent and was smooth as silk. I had totally forgotten what a real lubricant can do. Everything else is marketing bullshit.
