Three things you should have, two things you use in certain circumstances, and one you need in exceptional circumstances.
So when to use, and when not to use. Well, it’s not really that complicated. Just slather the grease about and you’ll be golden. However, if like me, you like to play about, anti seize has a valid use. If your the kind of person who assembles things, and don’t plan on taking the apart for awhile, anti seize is your friend. Let’s take pedals as an example, you install pedals, they may never be removed from the cranks for years, if ever over the course of the frames life. Anti seize will stay around for a longer period of time than grease, which may wash out over time, or dry out. Anti seize, thanks to its metallic particles will always help prevent galvanic corrosion and jamming up.
So when the time comes to remove those pedals after a few years, you’ve a better chance with anti seize applied. However, if you plan on bike maintenance, with a good schedule, grease is just fine to use. I’d use anti seize on:
- Pedal spindles
- Bottom bracket cups
- Derailleur bolts
That’s it. Quite a narrow use clause for that one. You could quite easily manage without a can of it in the workshop.
My singlespeed, which sees alot less maintenance than my geared bikes tends to see more antiseize than grease. Purely based on the fact it gets taken apart much less.
Thread locker, aka locktite, is used on bolts that you bolts you just can’t afford to come lose. I’ve only ever used it on jockey wheel bolts, where they have almost zero torque, but you can’t risk them falling out. Use it on anybolt you want to lock in. People use it on handle bar bolts, chainring bolts, seat pin bolts and many many others. Just use the blue coloured one. The red is too strong for use on bikes.
So grease, grease is your friend with bike maintenance. Use it wherever you have metal on metal contact, be it screw, slide or rotate. Unless you have a need for anti seize, or locktite, grease will do.
