Just another reason I buy used. Why pay a hefty premium for a warranty when it does not help you in a case like this.

Please don't confuse ebay "asking" prices with "selling" prices. Many sellers never get their ask price. some are far from it. Value is determined once an item actually SELLS. Its easy enough to check SOLD prices.

Holy crap, you actually used JB Weld and expect it to hold a critical structural frame member on a bike? That is nuts. The JB Weld present is probably doing absolutely nothing to reinforce the frame at this point and the only thing keeping it together is the remaining intact aluminum stay. You might get luck and last a year or you might last an hour.
But yeah. The JB Weld sheer/tensile strength is NOTHING compared to virgin aluminum or steel. Its great for low yield applications like maybe sealing a cracked intake manifold but "repairing" a bike frame? No way would I ever consider that.

+1. THe reason the JB seems to be 'holding' is because the crack was growing so slowly in the first place. The first time the crack tries to grow it will make short work of the JB. But maybe the crack was in a state of equilibrium and was not growing - you might be able to ride for another while... I doubt it, but maybe.
If the JB does start to crack, scrape it off and just drill small holes at the ends of the crack in the stay - the super tight radius of the end of the crack makes the metal there weaker than the true strength of the metal without a crack, and a smooth round hole will be a much bigger radius that will be much less affected by this.

If you really want to go on a ledge, you can get a TI frame and CF fork for $999 at Bikes Direct.

dedhed +1 He is right. Before I did anything, I would contact the mfg and see what they would do for you. It never hurts to ask, and they might surprise you.
