Hallo to everyone!
I got a bump in my mtb frame. My lbs says I shouldn't worry but I am a bit afraid of "total failure".
The frame is scandium and is only 1260gr.
Should I dump it?
Tough to say. Maybe bring it to a couple more shops, and get a few opinions?
I got a similar dent in one of my bikes recently, more of a straight crease than the round crater you've got. I decided not to ride it even though some guys I trust said it was probably fine. I just didn't trust it.
Can't touch this!
Should be fine. Just bondo the dent and get some black paint and paint over it. If youe really worried do exactly what I told you and sell it.

That's the downtube, yeah? I wouldn't ride it. It's the most heavily stressed tube in the main triangle and one of the most common points of frame failure.
I certainly wouldn't bondo it. It won't do a thing structurally and will only serve to hide it from you should it get worse, nevermind if it ever ends up on the used market.
I agree with Bostontrevor. My friend's scandium MTB Frame had a similar dent in the same area. He talked to the framebuilder who, upon inspection, advised him to replace the frameset.
I think of it like an aluminum can. An AL can will support my weight if its shape and integrity is still cylindrical. However, if I place a small dent in the side and then try once again to balance atop of it, it will collapse instantanously.
thanks for your replies.
I think I'll get a new frame. It was a cheapo anyway. But the next will be at least 1500 g. I think. I am a bit surprised how light it was to damage it, I am not even sure how it happened. I think it was a small stone somewhere.
Now I am tempted by Ti if my dentist does not bankrupt me, but that's another story.
You don't bondo a dent in aluminum.One needs to be able to moniter it.
