oka, I see that about every frame now produced is alum. Now I'm familiar with it's riding charateristics; however, what is the duribility of it? I mean if I dole out 2k for a DeRosa made out of Alum, how long will it last? The reason I ask this is I read somewhere that Alum frames have a life of about 4 years. Anyone have any breakage with an older Alum frame? Or know if this is true?

Anyone that puts an arbitrary,unqualified and unfounded life limit on alumimum frames in general is full of bull sheot. It depends on how its made,of what,what your size and weight is, and how its rode. A garage ornament will last forever.If you worry about it buy one with a lifetime warranty.

that question. I'm not familiar with that frame but in general a lightweight frame of any material will be less durable. How long it will last is anyones guess.

If you are a lighter rider who wants to race or do fast rec. riding, lightweight Al is a great choice. If you are a heavier rider there are are more robust/heavier AL frames out there. If you want a frame to last a really long time you would be better off with a midweight steel or Ti.

I already had 2 steel bikes when I bought my AL frame. It comes with a 5 yr warranty. If it makes it 5 yrs great if not I get a new frame. IMO I would not drop 2 bills on an AL frame without a good warranty but then again I can't afford to walk away from a frame at that price.

I think that it would be fun to take all of the parts of a bike, separate them by material and then compare the weights of each of the piles.

It's kind of like the exploding carbon frame thread on the general board. Almost all of the higher end road bikes today have carbon forks. Likewise, the majority of high end bikes use aluminum stems, handlebars and rims. Breakage in these areas is likely to cause you more serious trouble than a typical frame fault.

I've never had a bike frame that didn't last longer than I wanted it to. I'm always looking around for a new bike before the old one is used up.

I agree with the other guys on this post. What it really comes down to is how well the frame is built. Was it heatreated, does it use high quality tubing, and were the tubes cut properly? There are other variables but these are the basics. Also, keep in mind that more money does not equal more durable. That are alot of cheap frames with big names that are not worth what they are asking.
