Alu frame fatigue?

[shovelon]

Dunno, that Trek isn't welded. Some kind of "Internal lugs" were used. Alu tubes were glued onto these lugs. The horizontal crack follows the tube-lug bonding line, so it seems as if the tube is detaching from the lug itself.

Ditto that.. The Trek in those pics is bonded aluminum. The lugs are separating. It is now junk. :cry:

Bummer! :shock:

It's toast.

So, your saying I have to tell my wife that the frame I bought, that led to me buying all those cranks, wheels, seatposts, skewers all that shit' is kacked and I also need to buy another frame? Anybody got any tips on how to do that and make it out the other end?

Nope - You're a dead man.

Yep, those aluminium Treks used glued lugs, i've got a 9500 suspension
track, bonding is all gone on the trailing arm, forget "wall art" it's been
laying behind a hedge in my garden for the last six years

Well sounds pretty comprehensively wazzed, better start looking for a steel frame then. Pity, I did like the paint job.
Thanks a lot for your input everybody.

I wouldnt kill it off just yet - I've just spanked the arse off a 1987 Peugeot alu frame thats not even glued to gether, just push together alu and it seems as though it will last a few more rides -

unless I'm mistaken Trek have a lifetime warranty.

May be worth a go... the only stupid question is one not asked after all?
