No, that's what a drivetrain looks like if you're unwilling to lube the chain.
Jeepers. Spend five bucks on a bottle and take five minutes a week to apply it. It ain't rocket surgery.
The church next door to me has a bike mission. I go over there and help out once in a while. The homeless guys who ride all winter and leave their bikes outside have better looking drivetrains on their POS 70s bikes.
As for full disclosure, I admitted to performing routine maintenance and replacing worn parts.
i clean and lube the chain about every 10 days on average during the winter. Depending on the weather the lube will hold up for a few weeks or a few days. I've tried all kinds of different lubricants too. This particular pic was taken maybe 5 days after a clean and lube (one reason I took it). Between the sandy salt water slush and the scraping action of the front derailleur it just doesn't hold up.
When this bike had a 7 speed drive train I was able to use some rust resistant chains that I found for a good price. Those faired much better but they were too wide for the 8 speed drive train I had last year. That's one reason I'm stoked about using an IGH because inexpensive rust resistant chains for single speeds are easy to find.
And it's not just me. The bikes I see in the bike room every day at work during the winter look pretty much the same. The bikes that are there less often look better.
It's not a matter of how much a bike is left outside, it's how much salt it's exposed to. In fact it's probably better to leave a bike outside in the winter all the time unless you get the salt off. Bringing a salt covered bike inside to warmer temps only speeds up the corrosion process.
