But njeee – if the inside of the plates and the links are left to get black, your cassette and chainring ends up black and gunged
Not really, the new lube is very effective. wipe it off the outside of the chain, so it looks clean, leave it on the inside, after a ride it’ll work it’s way into the rollers/bushes, where you want it. You can then clean the chain as normal, the grease will remain where it needs to be for a while. Not forever, but why get rid?
It’s not going to improve the life of your chain to strip every ounce of lube out of it. You can keep it looking very clean with judicious lubing and a reasonable cleaning regime, rather than over zealous cleaning IMO. I’m not a huge fan of the ‘stick it in a jar of white spirit’ cleaning methodology – I always find the rollers rattle afterwards because the chain is so dry.
As we’re also now getting into winter I’m happy switching to a thicker lube. It’ll attract more crap and the chain/cassette do end up looking filthy after a ride, but at least the bike doesn’t sound horrific after 100 yards! A quick clean in situ and it’ll end up looking spotless again, but still with some trace of lube inside the rollers. Depends if you want to take photos of your cassette or ride your bike 😉
