Stem needs some repair

I had an extremely slow speed crash (a snail in a coma could have been lapping me). I forgot I had my clips in and I went down. Thankfully I went down driveside up and I managed to get away with just a gash on my ankle.

But my profile headset is out of line I thought I heard someone say bash the handlebars until they get in line but I thought it would be prudent if I asked here before taking a 2x4 to my bars. I'll post pics after I clean myself up

What I thought I should have done, simple and easy. I appreciate the help on such a easy fix

Assuming it's a quill stem: loosen the hex screw on top of the stem as shown in the photo, align the bars relative to the wheels and retighten. It sounds like the stem was too loose to begin.

+1 to this, it's really important to loosen the fixing bolt first, otherwise you could damage your wheel if you really torque on it. Being able to easily loosen/adjust/tighten quill stems are the only benefit they have over the newer threadless stuff.

As you may have guessed by now you should never "bash" anything on a bicycle. And I would suggest that the mechanic who suggested such a thing is a hack. And since it is so easy to just loosen and adjust anything on a bicycle it's always a good idea to loosen rather than just brute force anything back into alignment.

Some may think that since it shifted due to the fall that it is too loose. I'd suggest that being tight enough to not move during normal use but loose enough to shift like this during a crash is a good thing. By absorbing some of the energy of the fall by moveing you redirect some of the force away from things like levers which could easily break. Since it took a fall to shift your stem around I'd suggest that it was tightened just right.

Simply falling over due to being clipped in is hardly a crash that warrants the handlebar shifting. The bigger danger with such loose components is losing control at higher speed when an off center bump causes such a wheel to shift - that could cause a real crash. Been there, done that and have the scars to remind me of it.

Since the bars are the FIRST thing to contact the ground a minor angle of shift of this sort doesn't seem to me like the stem is loose at all. And we also don't know if the rider was still holding the bars when he landed. If he was then much of his weight could have gone into pushing the stem over to the side such as this. There's a lot of leverage between the end of the bars and the locking wege of the stem after all.

After loosening the hex bolt on top a couple of turns you will likely need to tap the head of the bolt to loosen the wedge that tightens the stem into the steerer tube before the stem will move easily.
