New chain and sprocket?

[Dudeofrude]

As you know my riding is dry only and I used the white spray sticky lube and the chain gained tight spots. Perhaps that's my problem - all dry / dusty riding sticking to the chain.Actually why do we even need to lube, they are sealed via x or o rings.

Funny you should say that as I was watching a video from MCN the other day where Neevsey was talking about motorbike upgrades and what you realistically need to bother with etc
He said he doesn't lube his chains at all, just cleans them with WD40 after each ride to get the crap off and that's that. He reckons your chain will last much longer and stretch less with that basic maintenance? And the guy does know he stuff ?

Good video all round but skip to the  16 minute mark onward for the talk about chains
