is this one of those super ultralight crazy ass questions?
really? gonna skip chain maintenance to save an ounce?
that's just (insert expletive) insane.
expect to lube the chain every 250-300km or so.
figger out how much you need for one application.
multiply by x, transfer necessary amount to a small
eye dropper.
clean your chain before you lube it. use a rag to rub
off as much the grease and grit as possible. i suppose
you can use a rag you find roadside....wouldn't want to
carry another half ounce of cloth.
apply half a drop to each link, then work it into the bushings.
and then use that old rag to wipe off any extra. you really
don't need lube on the outside of the chain.
your chain will last the entire tour, possibly longer.
your cassette?....another couple chains.
