I'm just a Luddite that still uses the wider 5-6 speed chains because I still use a 6-spd freewheel, not the skinny modern 7-10 cog chains.

Chain wear is one of the reasons I'm fastidious about cleaning my bike (especially the chain!) after riding in the rain, and why I pretty much detest riding in the rain. Proper chain maintenance (cleaning and lube) takes time! Well, it is a LOT easier now with on-bike cleaning tools than 30 years ago with a can of kerosene and a toothbrush!

Besides, a clean, properly lubed chain uses less pedaling effort than a dirty chain! The reason is simple. That extra effort you're expending with a dirty chain is what it takes for the road grit to abrade the chain metal away... Heck, 35 years ago when I used to ride centuries in the rain, I'd even spray my chain down with WD-40 at the rest stops! Not the best solution, but better than riding with a dirty chain!
