>>951357Everyone's got his own method, but it doesn't require rocket science
you need an old brush/some old brushes, rags, water, degreaser, dry lube.
>take bike>put under water (Got a hose? Use that. Not under any strong pressure and aim diagonally/from the top, not straight into the bearings. Sadly I've got no hose, so I use a 1lt water bottle and refill it at a nearby tap)>keep liberally spraying aroundthen
>take light degreaser something>I use WD40, which people will scream at you for using, but it's really okay if you just DEGREASE with it (it's 2/3 degreaser 1/3 lube, and displaces water, so it will penetrate nicely in your now wet bike, no it won't hurt it.)>spray a bit of it on the cogs and chain, spin it while you're doing itwhile you wait for the wd40 to sink in for a minute or two, clean the front wheel or something.
Once a couple of minutes have passed...
>get your brush and rags and gently rub the rear mech and chain clean>rinse with a lot of water, repeat as necessary until most of the grime is gone, it doesn't need to be perfect, just remove any grit from spinning parts>take particular care on removing grit from INSIDE the chain links, that's where the wear happens.When everything is clean enough, let it dry.
>Once dry. take a reference point on the chain and while spinning it drip some dry lube on it, making sure it goes INSIDE the chain>let lube sink in for 4-5 minutes>take rag and spin chain while gently wiping off excess lube from the sides of the chainBoom, youre done.
Things NOT to do
>do not lube your cassette>do not over apply degreaser>do not lube over degreaser without wiping it WELL off first (also a good reason to use WD40, as it evaporates very quickly and is easy to clean)>do not lube a wet chainAnd dunno I guess that's it.
