I have a diamond back bike with an aluminum frame. will it rust if i ride or put it in the frame? is it bad for the bike?Aluminum frames do NOT rust the corrode and unless you live close to the ocean you have little to worry about with the frame. it will be the other components on the bike like the wheels and spokes that may rust if the bike is left outside. If you didnt pay much for the bike then plan on some rust if you leave it out!Aluminum does not rust, it will oxidize if exposed to the open air if the paint is scratched off. The oxidation will protect against any more damage and is stopped in it\'s tracks. Other aluminum parts will not rust but the mounting hardware may if it\'s made from low quality materials. On nuts and bolts you can put some chain oil on the tip of a rag and wipe these parts down every one in a while. On things like cables I use Tri Flow, it lubricates and protects against rust.No, but take care of it and it will stay looking good too. I keep mine inside. I clean and maintain it all the time! It\'s almost like a care, the better you take care of it, the better it will run.sophisticated task. search onto a search engine. this can help!Other related question
