It's much too compressible. I wouldn't even try this.

I dunno, I'd try it -- if I was desperate. What's the worst thing that
could happen? Loose headset?

That's about all, but it's annoying enough in my opinion. Of course,
the spacers are really not under a lot of tension since the weight of
the bike and rider is borne by the lower bearing, but I'd still be
leery of doing it. On the other hand, like you, in desperation when
the situation amounted to "improvise or walk", I'd probably think
about that as a possibility if the materials were at hand. By the
same token, though, in my case, I'd probably be able to scare up
something a little more rigid from the pile of junk in the garage.
One must, in such a situation, work with what exists. (Do not inquire
about what I used as the substitute for a fuse in a DC-AC converter
this past weekend on a road trip; suffice it to say that the device
survived and the assigned task was completed as a result.)

Oh, all right. The clip from a ball-point pen. There wasn't a
grunion in sight, since it was in Oklahoma. (And no paperclips,
either; they were out of season.)

That's not the subtle bit. The subtle bit is the Livestrong bracelet
rolling around the front wheel hub. A moment's contemplation will
suggest to the student that, barring unlikely interference with the
bracelet's integrity, there's only one way to get it on there:

Also, I totally think you have to go wireless for the computer. This
particular implementation just cries out for it. May I suggest you look
into the Filzer dB4LW?

when hubs had a little oil hole (instead of using grease) it was common
(maybe usual) to tie a loop of cloth around the hub to wipe up the excess
oil. The knot provided the weight to stop the cloth loop rotating with
the hub.

Yep.

The collar is actually one that was made for a seatpost clamp. With the
stem clamp and the collar both loose, and an Allen wrench in my pocket,
I lean down on the handlebars as hard as I can, while twisting them back
and forth around the steerer, also shaking them front to back to take up
any slack in the headset. I then let go with one hand while keeping my
weight on the other, to fish the Allen wrench out of my pocket and snug
up the collar.

This system, in addition to saving weight, allows quick and easy
adjustment of handlebar height, since it doesn't require moving spacers
nor re-adjusting the headset.

Don' need no steenkin' sf nut!

This system works fine for me for 1 1/8" headsets, but I'm not sure it
would work for 1" ones.

Didja notice the whimsical 4 leading/4 trailing spoke pattern? I gotta
get a better photo of that. It's really tough to do good photos of
spoke patterns.

I have a fundamental philosophical objection to wireless cyclecomputers.
One battery is enough.

A better solution would be to run the wire through the steerer. With a
typical 1 1/8" threadless fork I coulda done this, but the Winwood
plastic fork on my IRO doesn't have a big enough hole at the bottom to
fit the sensor through. I could cut and splice the wire, or possibly
install a plug connector hidden inside the steerer. I may wind up doing
this.

I'm not certain I like this position for the computer though. It's nice
for riding, but I sometimes bump into it while starting/stopping the bike.

Only lighter, stronger and with a greater adjustment range, assuming the
steerer hasn't been cut too short.

And if you looked, you would have noticed that in time these hubs had
all their chrome worn off by road grit that got caught in the oil of
these wiper. That was the first thing that caught my eye with these
cleanliness freaks when I first saw them, then there was the aesthetic
of a dirt rag on the hub spool, contrary to the hub's function.

Sorry

Nice, looks a lot better with large flange than small.
