    Hi All,

    Are you ready for the science bit?

    On a chain you've got the flat plate link thingies, attached to the round bits in the middle.

    I know that the purpose of oiling a chain is to stop metal on metal rub, but where should I be aiming to place the oil? On the round bits? On the area where the plates join the round bits? IOr elsewhere?

    I run a drop across each of the rollers (the round bits). These are the bits that come into contact with the sprockets and the sideplates of the chain.

    Where the oil actually NEEDS to be is INSIDE the roller (the round-bit), that's where the major chain wear occurs. A light film on the outside is more than enough.

    Put on plenty and then wipe off the excess.

    I love questions like this! I like it when people risk looking dense as well so I don't have to stick my neck out.

    My next chain question then is can you over-oil a chain and how do you know if you've done so? I'm quite clumsy and only have to pick the bike up to be covered in oil, which makes me think I might be overly zealous on chain maintenance.

    Once you have lubricated it .... you leave it on for a small while ... then try and rub it all off again - so I am lead to believe ... as you want it on the inside rather than the outside to pick up bits.

    Wipe, wipe.

    Repeat as necessary.

    Yup - Lube it, let it dry, then wipe the excess off with a rag - the inside of the rollers is where it's needed. If you allow too much oil to sit there the chain will get dirty quickly.

    The knack is to oil regular with a good quality bike oil, then wipe off excess. It's also easy to wipe off any dirty film. The key is little and often.
  10. In liquids there is less surface tension in between the two objects that on top of them so the liquid will actually push itself between the parts like ink runs up an ink pen on its own. So as long as you put enough (or too much) on it will find its own way to where it is needed.

    If riding a lot in the wet - you can't put too much oil on.

    Cos the rain will wash it off.

    Crumbs - that's brave (in the "Yes Minister" sense :biggrin: ) taking a chain apart :biggrin:
