I'll grant that stripping factory grease from a new chain is a faff but since, at a conservative estimate, a chain will last three years that's something I'll happily put up with for the massive saving in cost of replacement drive chain components.
I've just started immersive waxing. Pretty much the only reason is for cleanliness. But if the drivetrain lasts longer, that's a valuable bonus.
The first chain I bought was "pre-stripped". The place I bought it from charges £12 to do that. I had already bought the slow cooker and got the MSW from the same place that I bought the chain from.
After I'd waxed it and ridden it, I was sure (as much as I could be after only a few miles) that waxing was for me. So I bought a couple more of the same chain, from the same place, but with factory grease on.
I stripped them myself. I don't think I'll bother doing that again. I did it partly because I had plenty of the recommended chemicals already (white spirit and meths) and actually no other need for them. But all the shaking stuff in jam jars business, several times, though not the worst thing in my life, was still a bit time consuming, and my wife wasn't happy with the chemical smell that permeated the place.
These three chains will probably see me out, but if I need more I'll get them pre-stripped if somebody else will do it. Or even pre-waxed.
I agree about the time thing. I did the two new ones, then as a test did the one that was already on the bike again. I think it took me 11 minutes, and that included some experimenting with a couple of techniques. Once I've got the "waxing station" sorted out, with my various bits and pieces in place, this is going to be a 5 minute job, and that's if I just use one chain. Having chains ready to go means it's the time to undo the quick link, take the old chain off, put the new one on, close the quick link. And I'll save the time it used to take me to get the filth off my hands.
It's been nice to come back after a ride, get off the bike, lean it against the (dining room) wall. And go.
