Does anyone know where I could buy a headtube/ headset extender for a threaded (quill) fork and stem? I have seen them on bikes before but can't seem to find a place that sells them. I am exploring this option, as opposed to a Nitto stem with a long insertion tube, because I want to use one of the newer quill stems with removable facecaps (eg, Deda Murex, TTT Motus or Salsa SUL).
check the Serotta Website, they make onekeeter

About a year ago I picked up a threaded CF fork that had a steerer a little long for my bike. Rather than cut the (cromo) steerer, I got a few 1" spacers from my LBS and put them between the cap of the headset and the locknut.

If your steerer is long enough and has enough threads, you might be able to do something like this. The downside is that if you want to also raise the stem very much, the expander wedge is going to be working against the weakest part of the steerer (i.e.,the threads) and you could end up with a Bad Situation.

Attached is a rather poor image of the relevent portion of the bike. The headset is a standard Ultegra, now, I guess, an Ultegra "stretch."

i think a nitto makes better sense as its one less part to think about and they are beautifully made and cheap at harris cyclery......

but harris cyclery stocks what you may need but they dont have a pic of it.

Stem Raisers

Stem Raisers for Standard Expander/Wedge Stems $19.95

A stem raiser fits into the steering column in place of your present stem, and secures with a wedge bolt in the normal manner. The upper part of the stem raiser sticks out above the steerer, and is bulged out so that you can insert your original stem. The bottom of the original stem winds up a bit above the top of the headset, so you gain several inches of height.

You're right, Nitto probably makes the most sense and looks nice. It's just that I've gotten addicted to stems with removable facecaps. I've since found a Profile Design or Dimensions H20 with nearly as much extension as the Nitto and it has a removable cap and is available in black and silver. Not as pretty as the Nitto, but more convenient and just as inexpensive.

I bought a 90 degree quill type Profile H2O last year from Colorado Cyclist as I found it had more range than the Icon that came with my 1999 Trek 5200. It looks decent, is reasonably priced and there are lots of lengths to choose from.
