I'm looking for a tall 8+ inches stem. Preferably threaded. Diameter .833 (21.1). I would prefer a 26mm clamp size, but a 25.4 will do. I've looked on the net, but just can't seem to find one.

I'm trying to make a bike that is too small for me fit properly. Seat is raised high enough, but stem needs a few more inches. Next time I'll just get the proper sized frame, but this was a good deal. Thanks
