Also presumbly a risk on lo pros. Never considered that before but well worth considering, not least as I am in the middle of building a lo pro and only this afternoon pushed a quill stem as far in as I could.
I bet that there are a lot more people on here who have never considered this than those who have.

Thanks for sharing. I can't be bothered to UTFS but is there a GA2G style sticky/list of 'potentially dangerous shit u might not know about'? Years ago a GF had an accident because I'd over-tightened her saddle clamp adjuster (single bolt type) and over the course of months the bolt developed a fatigue crack and went twang mid-corner. Lesson = torque wrench.

i recently installed a 3ttt stem just to try it out for a short run. the neck of the stem was a bit longer than my current sr royal, but it seemed considerably shorter than my headtube. it went in easily, slammed it like i always do, but after tightening and loosening the quill, it took me nearly an hour of swearing, wd40ing and cooling to remove it. now i know why.

I need a short quill for a tiny head tube , not too long in reach either
Any ideas -

This problem manifested itself for me when the wedge-bolt got stuck in the head-tube. Luckily for my face, it got seized so badly that there was no way it was going anywhere in a hurry.
My next bike had even smeller head-tube, so this happened:Don't forget to check the quill tubing isn't butted (thinner in the middle) before doing this!

Once I was track standing on a lo pro, at a red light, at the head of a huge group of nodders, mamils, normal people who just had to get to work, etc.
"I'm glad I'm at the front," I thought. "Don't want these wankers getting in my way, slowing me down. I've got places to be"
I waited, poised and patient, unmoving, statue-like even, for the whole long light cycle. And when it finally went green I leapt forward, pulling on the bars in my eagerness to be away. And watched in uncomprehending horror as my stem slid smoothly out of the tiny headtube.
I managed, somehow, to stay upright for maybe a second more, before crashing to the ground. From there I could only lie still, bullhorns clutched tightly to me, watching the other cyclists look down at me as they passed, eyes filled with amusement, annoyance, some just plain incomprehension. But worst of all were the eyes that looked down, at this poor incompetent cyclist lying on the hard asphalt, and looked down with pity.

Hehe. Is this documented in DYOC?
Perhaps it is common knowledge to those using quill stems on frames with short head tubes, but it was news to me until my girlfriend came home from work with her handlebars in her hand. It was only luck that she didn't have an accident. Steerers taper at the bottom so if your frame has a short headtube make sure you don't insert the stem too far into it or the expander will expand onto the tapered part and can dislodge far easier than if the expanded part of the stem is in the proper place.
