How long do aluminum frames last?jbeck

I just purchased a 99' Trek 2500 frame, headset, and fork on ebay. It has some paint chips and is in fair condition. Besides just looking a little beat up is it O.K.? How long does a frame like that normally last?
Be careful, that is one old bike. Check for cracks; Trek. (nm)onespeed

Look to see how many AL MTBs you see rdiing around. I own a '98 and it's never had a problem.

As long as your frame was not crashed or otherwise abused it should last a long time.

I own a '99 Al mtb. No problems whatsoever. I would not worry too much about it failing. While Al has the shortes fatigue life of all bike materials, chances are that it will not break after only a few years. The fatigue life might be 100 years compared to 500 from steel (just an example). I've been riding Aluminum and have only damaged one frame, but it was because the derailleur shifted into the spokes while going pretty fast.
I would not worry about it. Just check for cracks because you did buy it used.
Long, long timeRJF

Hell, I have a 1992 aluminum MTB that is still going strong. I raced it for the first 3 years of its life, then rode it another 5 years off-road, and now use it everyday as my commuter. It's bomb-proof.

Has anyone ever known anyone who has had an aluminum frame die from old age? Probably.

I've had my share of frame failures. Here's what I think; it doesn't matter what the frame is made of, it's how well it's constructed and how it is ridden that determines how long it will last. Recently, I broke a 2 month old Merlin MTB – hitting a tree stump at 40mph. I've cracked a Giant TCR ONCE frame with only 3000 miles of hard riding. Most interestingly, after 30,000 plus miles of commuting and loaded touring, my 9 year old Nashbar $89 aluminum touring frame is yet to fail me. See, sometimes you do get more than you pay for!
ABSOLUTELY impossible to answer this questionKerry

As others have mentioned, it's about how the bike has been ridden and how well it was designed and built. None of those factors is directly measureable by you. Further, there's never been any data published against which you could compare even if you did have the data. You just need to inspect the bike closely on a regular basis. I just talked to a rider today who said his Specialized Al frame had been squeaking for a year, but nobody could find the crack. A day after a race, the chainstay broke right off at the derailleur hanger.
