greasing chainring bolts….
got a new blackspire stinger yesterday so like a giddy child with a new toy i went about fitting it last night….while the chainset was off i decided i might as well replace the chainrings, but i didnt put any grease on the threads of the chain ring bolts….Posted 4 years ago
am i asking for trouble in the long run or can i get away with it?Pimpmaster JazzMember
Lube on a thread actually lets you tighten the bolt more.
True. If I was going to use a grease, I’d go copper-slip as you could argue it’s an anti-seize, so doing what you’d want the grease to do. Grease is great for parts that move against one another, but an anti-seize is better for parts that don’t.Posted 4 years agoJoeGSubscriber
I usually use grease on mine. I have used blue Loctite in the past, but it can be a PITA to clean off, especially from the female threads!
I just put a bash on a 2 week old set of XTR cranks. I’d say that Shimano uses a threadlock on them at the factory; it took quite a bit of force to break them free! So I used the thin, green loctite (low strength for screws) when I reassembled them. We’ll see how well it works.Posted 4 years agoYakSubscriber
Loctite 243 (blue) for me.Posted 4 years ago
Have used grease before when I had no loctite to hand and it resulted in bolts coming loose. This was on a single ring set up with the thinner single-ring specific bolts. Never had a double/triple come undone with grease or Loctite, but having had the single ring bolts come loose, I won’t be using grease for any set-up.
