7 speed hub in 130 frame

Will I end cold setting a frame at spaced for 130 mm over lock nut distance if I use a 126 hub? I
guess I'm lazy and don't want to put in spacers unless necessary. But then I don't want to end up
with a 126 spaced frame either.

If it's a metal frame, it shouldn't be a problem, but I wouldn't advise this for a plastic frame.

Adding a 4 mm spacer on the left, re-centering the axle and re-dishing the wheel would be the better
way to go. It's not _that_ much work and will result in a palpably stronger wheel.

Did you ask if a frame will permanently deform from clamping a 126mm hub in a 130mm rear end? No.

Using the wrong spaced hub will not permanenetly 'cold set the frameset but why not add 2mm to each
side of the hub?

I would think it'd be more convenient to do the latter and
then adjust the limit screws on the derailleur as needed.
Sheldon, is there any major benefit to putting all the
spacers on the left?

And while we're at it, I wanna review this:

What's the short explanation for why wider wheels are
stronger?

Thanks Yoni.

You will re-center the wheel by tightening the non-drive spokes.
This will result in the non-drive spokes sharing more of the load than before. More even sharing of the load amongst all 32 or 36 spokes makes for a more durable wheel. Lateral stiffness will also be improved when the rim is reacting to forces that want to move the rim to the left, because the spoke support angle of the right side spokes will be improved.
short enough?

Theoretically, it will allow for the left and right side
spokes to be more even in tension. Still not equal, but it
will mean redishing the wheel to move the rim to the left.

It also won't change the chainline 2mm- maybe an
important thing?
