I don't understand the issue of tightening the riser. You put it in, tighten the hell out of it, and forget about it. Then it's just part of the steerer tube and I should be able to just use the headset and starnut like normal.
Do you think that tightening the star nut screw would pull out the riser?
What if I bought the riser and then had it welded on the steerer so that no joint was protruding?
I'm trying to visualize where all the parts are going to go. Are you saying the upper race of the threadless headset is going to sit on the threads of the old fork? If true, I doubt it'll stay straight. There's enough play there that the upper bearing cup will wiggle around and destroy the bearings.
