thus the angle of the spokes decreases.

Okay? Is that the reason you simply cannot make
the back fork wider? At some point the spoke
angle will make for a wheel that isn't
strong enough?


People have been predicting doom in that regard for a very
long while. In theory maybe but in practice not yet.
