long term storage in a non-climate controlled garage
i have a steel bike i'm thinking of keeping in my parents garage for when i visit them once or twice a year. they live in arizona but where they are it gets very cold and very hot. temps in the garage will swing from 10F to 110F. but there is little moisture. can i keep my bike in there without worry? i assume the tires will decay rather quickly, but is there anything else i should worry about?
What is the humidity like? High humidity will make steel rust and aluminum corrode anywhere it isn't protected. If it is realtively dry the only thing I can see happening other that degredation of all of the rubber parts is the lubricants drying out, and dust collecting on the drive train components. Other thoughts anyone?
Should be no problem if the bike is lubed prior to storage.
Be sure to hang the bike up.
I have read that concrete floors will draw the moisture from the tires.
I have bikes that I use 2-3 times per year hanging in my garage (-20 to 120F) with no ill effect.
If they have a washer or a dryer or some other motor operated unit, try to store the bike as far as possible from that. There is a very small amount of ozone that comes off of motors and over time; it ages the tires and cable sheathing. It isn't usually a big effect but rock hard tires can cause you pain.
I bought a bike on E-Bay from Arizona. I'm guessing it had been in a garage for about fifteen years. No rust. But, the "solar heating" of the afternoon sun must have gotten that garage up to some astounding temperatures. All of the grease in the headset had "boiled out" and its residue dried on the headtube. Likewise, the grease in the wheel bearings. The plastic fittings were brittle and cracking.
So, if the garage has a "cool" side and a "hot" side, you really want to hang it up on the cooler side.
My father in law lives in Tucson & Phoenix before that. Humidity is generally extremely low (come out of a swim pool & be dry in minutes). Your bike will be fine in the garage, just be sure to lubricate everything regularly & expect to replace the rubber & plastic parts when they self destruct from solar uv & high temperatures.
