I'm measuring the dropout spacing, and I'm not getting a solid number. I'm getting somewhere between 125 and 130. Below is a picture of what I'm measuring...am I doing this incorrectly?



From what I've been reading and seeing, the space should measure 120mm, 125mm, 130mm, 135mm, for instance - not somewhere inbetween.

I'm measuring the spacing to purchase a hub to get wheels built, but I'm stuck

I'm measuring from one inner-edge of one dropout to the other inner-edge of the other dropout, just like: http://www.sheldonbrown.com/frame-spacing.html

Also, when measuring the spacing between the fork ends, I'm getting a measurement of 99mm.

Is it possible that the alignment on either the fork or frame, or both, is off? I would think steel is stronger than that...but what do I know? Hah.
