Hard to replace chains daily in the winter.

I used to "service" my winter bike's chain every spring by taking it off and tossing the rusty lump in the trash...

Worked for 3 seasons with about 10x more miles.

This chain only had only seen a couple hundred miles over the winter, had been lubed regularly and cleaned a couple times... Didn't expect it to fall apart. Oh, well... at least I didn't rack my nuts or faceplant.
