Bike Question

My racing bike is a “99 model with a threaded headset. I think I’m at the end of the line in terms of upgrading it. It’s tricked out pretty good with DA and H3 wheels. There’s always room for fine tuning, but maybe not for this bike. For example, I might like a new carbon fork instead of aluminum or Vision Tech bars. But all of the new stuff is for threadless models. Maybe, I could use the threaded–to–threadless adaptor sold in the catalogs?

If you go to the expense of new bar(VT with int.stem) and new fork all that is left is the headset.The least expensive of the lot.The most it would cost is a little over 100.00 for a KING headset.
