Headset Spacer concerns

As I was musing in another topic, on my 1974 Zeus track bike project, “The nice fork I bought here on C&V/BF looks great, but the steerer is long and the top nut bottoms out while about 9/16” of threads are still exposed. Hmmm, if I could locate a spacer to fill that instead of cutting the steerer, I could leave the bars higher while not sourcing a long stem, right? Looks like plenty of support for the stem.” Well, measuring a bit more accurately, I find that the “excess steerer length” is from 19.9mm when only engaging the top nut threads 1.5 turns (likely not enough, eh?), down to 16.7mm all the way down. Furthermore, there’s a 1.5mm keyed washer which could take the latter figure down to 15mm. Looking online, 15mm x 1” silver aluminum spacers all seem to be out of stock everywhere. Again, is it acceptable to “stack” spacers? And I’ll presume that the existence of such spacers (wow, I’ve seen 40mm ones out there?) implies that such things are indeed used out there, presumably safely.

Yeah I don't see any issues with that.

No issues…



Indurain did it and it worked “ok” for him if you need more proof.

It absolutely is.

Mine,




And this, it was my inspiration.

Hetchins Duel

I made it from some SS thick wall tubing that shined up well, I can send you a chunk if you want. Has to be pretty level and square. Wasn't to hard to do.

Sounds like I should proceed. Now to find them online, seems like a lot of sellers have "supply chain issues" So perhaps a 10mm and two 3mm.

If I had access to machine tools, I'd be all over that offer!

No need for machines, flat surface, emery cloth, small level, square, calipers and a bit of chi/patience.

I can cut the spacer with a pipe cutter that gets very close on both ends then you sand/file them down to finish.

I have never been a fan of stacking spacers, especially aluminum that can easily be made to be one piece.

The stainless shines up better and looks so much better than anything other than chrome.

I can send you a piece anyway if you want, just need the size.

Just make absolutely sure that the expander is below the threaded part of the stem.

And maybe a bit more for good measure with that much stem sticking up.

I detest the idea of cutting a steerer especially if you’re cutting less than an inch.

as my hairstylist says when she breaks out the Aquanet “stack it to Jesus Honey”.

OK, you sold me! As a bonus I get to spend extra time on the buffing machine making it glow. I figure on a finished spacer of, eh, 16mm, and I'll PM you an address.

All about the glow, easy peasy on this. I did it by hand with Scotch-Brite and Blue Magic polish, you may have to sand a bit but probably not much.
