Sheldon can help you with that:

11-speed should be same as 10-speed.

5>6 & 6/7 > 8 the hub axle width increased , then it stopped (except Tandems).
Way back there was a 110 track width >120>126>130. [MTB 135]. give or take a MM..

for road,
5s = 120mm
6s = 120 later evolved to 126mm
7s = 126mm, and later evolved to 130mm where it stayed through 11s
mtn bikes were 130mm for 6&7s, then went to 135mm, and some went to 140mm.
Though the number of speeds were a factor, it was an evolutionary process, and doesn't tie to the number of speeds directly.

I know this is an old thread but it's exactly what I'm curious about. If I read this right, a five speed hub is 120mm. So if wanted to build a SS rear wheel for an older 10 speed, I'd start with an 120mm hub?

Yes, 120mm was the standard for 10 speed (5x2) bikes from the sixties through the seventies until 12s and more led to the change to 126mm.

Yes and it was roughly a month later.

What about simply measuring the actual frame's drop out width? Or did I miss something? Andy

Are the full-size 6-speed hubs actually 126 mm, or are they 125, with dropout spacing at 126?
Yeah, yeah, yeah. I know it would be hard to ask for more trivial info....

Does it matter?
In the real world there's always tolerance and 1mm on axle or frame width isn't out of line.
However, in general the axles are usually close or just shy of the nominal, and the frames close or slight above, so the wheel can slip in easily, and the frame isn't so wide that the open QR would bind. This sort of staying on your side of the double yellow is SOP in tolerance guidelines for parts that have to mate smoothly like nuts and the wrenches that fit them.
