Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

rust after riding

It was raining today as I rode to class, but I thought nothing of it. My bike has been sitting, out of the rain, for two hours now and I just noticed spots of rust on my chain and drive side cog. I'm going to be at school for another 6 hours and I don't know what to do about this rust. What do you wet climate guys do when you get to school/work?

Not much you can do about it, other than find a covered space to lock the bike. Otherwise, get home and wash the chain, then re-lube.

Well I'm keeping the bike with me indoors. I don't care about the rust on the cog because that's easy to clean, but that might be harder.

Think about more important things.

A little surface rust isn't a big deal, clean the chain and you will be good to go.

It will also help to keep it well lubricated.

Nothing.

Your drivetrain parts shouldn't be showing rust like that. People who typically live in environments where it rains constnatly, all the time use a heavier chain lube on their commuter bikes. The rain doesn't wash it off and the runoff coats the cog/chainring/chain. Preventing rust. Higher quality parts like a kmc stainless chain, phil cogs, surly staineless rings help quite a bit as well.

Yeah if it rained often enough I would say invest in a stainless chain, but once you relube it and ride on it enough, the the rust will wear off. The only thing I might do is to clean the chain with Park or Finish Line chain cleaner in a few days once its dried. As the chain wears the rust bits will come off and it could work its way into the chain linkage and cause more friction. Scrub the chain with the chain cleaner and relube.
or not...what ever you want.

People put saddle covers over their Brooks saddles. ... Why not put a cover over drive train? You know like ladies bonnet or something.

Just put some teflon chain lube on it, get a heavy/wet one for rainy weather. Don't worry about it.

Don't worry about it. It's totally insignificant. You don't want your frame to rust, but your chain and cogs are easily replaceable items (plus, they aren't the kind of things that will rust through). They are exposed, bare steel, and if you use any kind of lube that washes off easily in rain (especially wax or dry lubes), you will see rust like this. Use a more persistent lube. Just plain lubricating or motor oil works well for this kind of application. Apply sparingly, and you will be fine.

Let your frame rust into oblivion so that your bike turns into a pile of dust next time you hit a pothole, and you are left standing there in the middle of the street holding your handlebars.

speaking of things unlikely to rust through, you really shouldn't worry about frame rust either. unless you forget to bring your bike inside for fifteen years, chances are you're not going to do any harm that isn't reversible. Go check out the C&V forum if you don't believe me—"oxalic acid" is the search term.
