you didn't say how long you would be on tour.....or more importantly
an estimate of total distance you plan to cover. put a new, quality chain
on before you leave, should be good for 4000 km, give or take 1000
depending on conditions.
take a bottle or two of finish line chain lube. red cap for dry conditions,
green cap for wet. (green is gooey-er, picks up more gunk but lasts
longer).
some airlines may confiscate your oil. if they find it. they probably
won't if it's in ziplock baggies inside your empty water bottles
in their cages on your bike in its box....
i like to lube (small drop on each link) every 500km. wipe the chain
with a dry rag thoroughly before lubing, get as much icky stuff off first.
roll the bushings to get the oil inside, wipe off excess.
