Bought a used fork off ebay, Argyle 302's and the steer tube's too short. With my FSA Pig Headset, I'm only getting 15mm of tube for the stem to grip. Any headsets out there with a low enough stack height that could help me out? Maybe a new stem? Worst case scenario, I sell the fork.

Thanks!

There are such things as steerer tube extenders available, maybe of some use to you.

What would you call the coupler below? I'm trying to find something similar online but I'm not having much luck. If I can buy something like this, my friend would be able to weld it on.

For such a low stack stem you'll have to look into BMX stems. Problem, they'll probably use a BMX handlebar diameter ... (22.2mm)

The lowest MTB stem I could find is 30mm, and definitely not enough for your 15mm.

Have you tried removing the top piece of the headset for example?

Interesting. Anyone have any experience with using this extender? The site doesn't provide any details as to how its secured to the existing steer tube.

I have not. But it'll only add ~5mm.
My best bet here is to extend tube.

Thanks!

For those of you interested,

I think it's a nice quick fix for a road bike but I don't know if I can trust a simple clamping system to keep my handle bars from popping off while dirt jumping.
What do you guys think?

Standard 1&1/8th headtube? Crank brothers used to do a low stack headset around the 20mm mark. Look on eBay, there are some in America. If not low stack stems, again not available brand new but spank used to do a spike that was about 25mm stack but that's still not low enough for you I guess.
I am sure the pig is pretty high stack so you should be able to sort it with some shonky extender

Unhip-crayon were you able to locate one of these?

Had the same issue once.
DMR defy stems were as short as I could find in height on the steerer.

It's not something that you would locate, it's something that you'd have to get a machinist to custom make one on a lathe.

Precise measurements of the existing steering tube would need to be made as it would have to be a tight fit and pressed into place.

Well, I'm not going to risk it, weld or no weld. Having said that, my 2012 totem is on the market. It is the totem RC2DH solo air model, limited edition graphics, 40mm stanchions, serviced, well kept, and breaking my heart to have to let it go. Lots of mtb'ers agree that it is arguably one of the best single crown forks ever made, and after riding it, as well as tons of other forks, I would have to agree.

You can press out the old shaft and press in a new one,or better said it is possible to do that.
There are some guys on ebay (germany) that are offering that for around 69 Euros,I did it with a fork on my dirtbike and had no problems with that,they can also press in a shorter piece in the top of the old shaft to lenghtend? it
