Why do you want the bike? If you just want to have it in your collection, go for it. If you want to ride that bike fast and long, look for metallographic laboratories in your region. No one knows why the boss was ripped off. There are several methods of non-destructive fractography and they are able to assess the structural integrity far better than you or ...

You'll need to very carefully inspect the area around the boss that's been ripped out, as well as your usual second hand frame check. If the bike was ridden after the damage cracks could easily have spread and you might be well on the way to a two piece seat tube. This groove could be the start of a problem, but it's probably just a scar from where the cage ...

Was this likely caused by my stupidity? I wouldn't go that far, but play in the stem/headset assembly certainly could have been a contributing factor. Just take a second to imagine to torque and force applied to that small area below the weld when you hit a curb or pothole if the assembly is not tight. The bottom of the headset is somewhat wedge shaped, ...

Is there anything I should consider doing to reinforce or protect further damage? In my opinion, the frame is toast. You can drill a hole ahead of a crack to try to keep it from spreading. Determining where "ahead of the crack" lies is guesswork. You can't see where the crack ends because: it is three-dimensional: it could extend farther inside the ...

Maybe it's because the fork is too large for the frame.Therefore,causing the crack.

Consider the scratches as war wounds. They're only cosmetic, but they show you ride; that you're not a cycling poseur. If the scratches really bother you, consider bogging it with automotive filler, then file and sand to shape, and paint. It will add grammes of weight though! As for adjusting the hoods, you need a 5mm (maybe 4mm, maybe 6mm) hex driver ...

From the first picture, it looks like the shifter has been knocked out of position but there's no damage to the bars themselves. If that's the case, it should be an easy fix. A good bike shop wouldn't charge much to put it right. The scratches on the shifter are only cosmetic, and I'd be surprised if it was cost-effective to replace the parts unless you (or ...

The first question is "is the handlebar actually bent?". Brake levers/shifters are just clamped onto the bar, and the clamp may have just slipped. It's not clear from the angle of the picture that the bar may be fine but the clamp on the brifter slipped. You can peel back the hood (back to front) and adjust the clamp if this is the case). If it is the case ...
