If you break the top bar, seat post or fork on your bicycle, just wrap it with this stuff. (Look at the back of the box -- they marked in black parts of the bike that you can use this stuff to repair, or that they suggest using this stuff to repair or something.)
"It hardens like steel, 100x stronger than duct tape!"
Yeah, this won't turn out horribly, horribly wrong at all!
edit: this seems to not be an accident, as they've put
up this video where they use it to repair the frame of a bike -- which is quite impressive, but the fork gets more stress than that and there's not enough room to put more than a few inches of the stuff there where they used a whole foot on the frame.
I mean, this stuff looks pretty cool, but suggesting that it can be used to fix your *fork* right there is asking for a lawsuit when somebody loses all their teeth or worse.
