I was wondering if anyone knows of a non-destructive modification to extend the handlebar reach on a downtube nova (via an ahead, adjustable quill stem, or threaded to threadless adapter, etc)
Here's a picture of what the handlebar assembly looks like:
The top, height adjustable piece, doesn't seem like it's removable. I took the handlebars off the clamp, and tried to pull that piece all the way up, but there's something preventing it from sliding completely out. I was thinking if I could get that piece off, I could try to find a pipe of the same size, and maybe fit an adjustable quill stem or something similar in it.
Has anyone done something similar that's applicable to this bike? Any ideas?
(EDIT for clarification: The goal is to increase the saddle to handlebar distance)
