azonic DS-2 sturdieness

I bought my Azonic DS-2 used from a friend, and it came with small cracks (4cm high) in the head tube. Small, but noticable. I put a stainless steel headset in, and nothing has really happened. I have, however been doing bigger drops, and I am getting paranoid. Should it hold up?



P.S.-
I should have pix soon.

No it shouldn't. I would not even attempt it personally. I am impressed it lasted this long.

They aren't THAT strong. Really the alum ones don't have a great reputation. They are just strong for how little they cost.

AND IT ALREADY HAS CRACKS...

I just got an Azonic DS-1 with manitous etc, and the frame is pretty strong IMO, although I havn't gone very big on it yet, only about 3 footers. How big have you gone on it, because with cracks in the headtube would surely upset the whole landing feel of it?!

Even though it has 'held' up til now, keep in mind that the frame had to have seen a lot of stress cycles to make it crack there. That means one of two outcomes. Either
(A) The frame had a weakpoint there that was so far ahead of the rest of it that it just had to crack and the rest is fine, which warrants a re- weld or the like.
(B) The frame was relatively uniform in stress. That would mean that the cracks happened ahead of the rest, but others may be eminent. If that is the case, treat it with caution.
I have had decent success rewelding the brake tab on my XTC, and a headtube may be doable. But the place I draw the line is in frame junctions, especially in the front area. THe biggest thing I can tell and I've said it before is don't let it surprise you. Polish all your areas with a fine tooth comb, often. Aluminum, though it cracks, will still do so at a slow enough rate to be seen with a lot of time to spare. The vids people show of head tubes getting ripped off, bad inspections. Or lack thereof.
For the ammount you need to reweld, if you so choose(which I would look into) most pro weld shops will hardly charge anything for. The place that did tig work on my brake mount didn't even charge anything.
