Can I use the above stem riser with my 1" steerer so that I will have enough tube left to adapt my frame to a threadless headset? I believe it could be perfectly hidden underneath the spacers, and it might be stable enough, too. (road bike)

I went with a 1" CK nothreadset because I found it for $65.

The issue is that I cannot afford a new fork right now. This riser would cost $15.
