As far as spacing, I'm only talking about the rear dropouts. The previous owner bent them a lot so he could use some ss wheel that I believe was spaced to about 130mm (i got rid of it months ago, because it was also damaged with a bent axle). So the measurement I took with my caliper that was barely long enough was about 142mm. Now i'm pretty sure they wouldn't space the rear dropouts to 142mm, and I was hoping someone had some information on this frame, because it is difficult to find info on the older leader frames
