I'm being offer Giant CFR Team frame 92'. The frame is my size. I would guess it has a couple of thousand mil. Its a carbon composite frame. Has anyone riden the frame? What's its weight? Is it a quick etc? Any info. would be greatly appreciated.

Thanks

How long is a cf frame good for?DINOSAUR

I know absolutely zilch about carbon fiber, my two bikes are aluminum and steel. You are looking at a carbon fiber frame that is 11 years old with unknow number of miles on it. I don't know if it's true, but you can expect to swap out a cf frame every 3 or 4 years.

Perhaps someone who has more knowledge about cf can give you a better answer.

...a really lightweight aluminum frame every 3 to 4 years.

:-)

Seriously, it is like anything else out there...some well made CF frames will last forever, some not so well made ones won't last very long at all. You cannot generalize based solely on the material used.

The biggest problem with the first generation of CF frames that used aluminum lugs, back in the 80's, was that they often had problems with the glue used to bond the tubes to the lugs breaking down. I think this problem was largly resolved by the early 90's.

FWIW I have an older, early 90's, Look KG.156 that is absolutly fine. I do keep a slightly paranoid eye on the lug joints though. But I've had zero problems with it. (I also have two OCLV's which I expect to last "forever".) The only frame I've ever had that failed was an early 90's Cannondale that finally cracked somewere in the seat-tube after about 10 years of use.

Inspect the frame that you are interested in very closely. Providing it looks solid, pay a price that is in accordance with it's age. It can't be very expensive considering it's age and the fact that it is used. How much do you have to lose?
