The point was the trouble of pressing the master link.
They are "troublesome" in a way. O-ring chains are higher friction. They don't like to be pressure washed. They don't like solvents that hurt rubber. They don't like penetrating oil. They are
supposedly "ruined" if one oring is breached.
Don't like this--Don't like that. picky, picky, picky. They supposedly last longer, but there's a tradeoff. High tech = picky. Then there's the expense.
Perhaps, a better description is that they're picky. Serowbot didn't seem to like them. However, sealed chains are actually marketed toward dirty conditions, so....
Roller chains seem simpler. clean and oil, rinse and repeat. There's probably a bit more to it, but you get the picture. If it gets dirt in there, take it off and wash it in kerosene, oil again, rinse and repeat. How dumber can you get... in a good way?
Maybe I was going along with Serowbot too. He acted like they were trouble, and add the other stuff, so....
I like something that is no worries. Why do you think I have a beat up Savage? Well...part of the reason, anyway.
Any opinions on ZDDP?
