I just scored this frame and it's in excellent shape with almost no scratches on it, but there are cracks where the tubes join. Anyone know if these cracks are just paint cracking from frame flex or do they indicate imminent failure?

Get the frame professionally checked by an LBS that knows how to actually check CF frames. Depending on people at the far side of the internet to evaluate via picture is needlessly risking your safety.

Alternately, ride it based on photo evaluations, just make sure that your life insurance is paid up. Your wife will thank us.

That's just how they looked even when new. Thin paint and less paint prep than current frames (sanding).
Precisely right. My 2005 Madone frame had those joint marks when I bought it. Don't worry about them.

A substantial internal lug reinforces those areas and extends quite a bit into tubes beyond the mark. The comments about life insurance and such are based on not knowing how these frames were made.

Actually Wim, the comments were made on basing readability of a bike from pictures on the internet. Maybe you are able to determine structural integrity via picture but I am not able to.

Still stand by statement of taking it to be properly checked.

:D

I had a Trek 5200, same construction. You could see the joints from day one, no biggie. That bike was an 2001, it is still being ridden today by another rider.

ExChef: There was no need to guess just from internet pictures.The title of the thread ("1995 TREK OCLV 5500") established beyond a doubt that these imperfections are not defects, but harmless indications of joints. But as said, you had to know how these frames were made.

Why would a bike store do an evaluation of a bike not purchased there?

The upside:
Everything is fine. You don't make a sale.

The downside:
The rider crashes. What caused it, is it even related to the frame at all? Are you liable?

rm -rf,

For the same reason that a shop will service a bike that wasn't purchased there, income. Who said anything about a free inspection? Of course, as the expression goes, you get what you pay for.

I'll step out of this thread at this point. I don't have a dog in this fight.

Orangegore best of luck.

As others have said, no need to worry. It's where the paint has cracked at the lug joint. It happens to just about every OCLV of that era--worked in a shop back then and that was Trek's explanation at the time. The paint is thin and not very flexible. If you find a "nude" OCLV from that era you'll see the lug joint.

I have a 1996 OCLV 5500 that has the same paint crack. It's still going strong.

Paint is very flexible, it doesn't just crack on it's own. There's always something going on underneath in the structure.

What is going on? Movement of some sort. What kind? Scan it to find out.
