Aluminum HT - Cracked at post - Advice
I have an aluminum frame hardtail. I just noticed a substantial crackon the frame where the post goes in, above the joint. See pics attached.
I could not visually see any other cracks. I did change to a KS seat dropped a month or so ago.
Should I stop riding it?
Should I weld it?
Should I throw it away?
How far down does your seatpost reach? Looks like not far enough...
Weld it or throw it away!
your stuck between a rock and hard spot.
If you weld you weaken the surrounding metal, if not your screwed.
If you could keep that surrounding aluminum cold while its welded you may be ok, but your options are those two, weld or throw away.

What kind of frame is it? It is a pita to fix that, and will run the risk of never being right. It might need to be heat treated again, and you're not really solving the problem that led to the failure in the first place.
I'd scrap it.
