Digging this thread back up as I recently purchase a 1" threadless Kestrel fork - see here... http://www.ebay.com/itm/110880568776...84.m1439.l2649

And so now I need to get the rest of the stuff to make this work. I presume the two things I now need to do the swap are a 1" headset and threadless stem. Anything else?

As for the headset, do I need to have any concerns about different bearing diameters or are all 1" headsets the same? Reason I ask this question is this comment pasted from above.... One caution. Older bikes had a 26.4mm headset compared to the newer 27 mm headset bearing size. My old fork bearing race would not fit this fork. I had to update my headset to fit the fork to my bike.

For the stem, I know 1" stems are kinda rare. Should I hold out for one of those or just get a 1 1/8" and use a shim? Handlebar diameter is 26mm, which seems "standard" for the era. I plan to leave that as-is for now.
