steerer tube spacers (between bearing cap and stem bottom)

I'm seeking a more upright riding position. I've added a couple more spacers around the steerer
tube to bring the distance between the bearing cap and stem bottom to around 1.5 inches. Is this
too much? What is the maximum distance between these two points that can be safely added?

Steel steerer? There's probably no important limit beyond avoidance of looking wierder than your
social circles will accept, as long as the top of the stem's clamp is still no more than 5mm above
the top of the tube. If the tube's exceptionally thin, check with the manufacturer for their spec.

On a carbon-tube fork, you would probably be at or past the allowable limit already.

I'm not sure if there is a generally recognized limit for an aluminum steerer. I'd check with the
fork's manufacturer for that. I would expect it to be like steel, though; no real limit beyond
correct height at the top of the complete assembly.

Yes, steel. Thanks again for the knowledge.

I'd be looking for a stem with more rise before adding any more than the current spacer stack. Is it
a road bike or MTB? MTBs are easier thanks to wide availability of cheap high rise stems, and there
are riser bars too which can add up to 3" compared with a flat bar.

Why not use a cheap high rise stem on a road bike? Is there a difference between mtb and road stems?

ISTR that mtb bars use a different size of clamp than road bars; mtb is 25.4mm, road is 26mm if I'm
not mistaken.

OIC. Well, a cheap high rise stem was easily found for my road bike, in the small LBS that I
frequent. It's a 45 degree rise, 130mm stem. It gives me approximately 3", maybe a little more,
certainly no less (I didn't make a huge effort to measure accurately).

It's labelled "Dimension", and is from QBP.
