Curious about 130mm dropouts
Was there a specific demarcation, or did every manufacturer make the change to 130mm in a staggered fashion? For instance I bought a new wheel set, then proceeded to the garage to cold set my frame in preparation, then found it already was 130mm. Somehow I just had it in my head a 6 speed freewheel was 126mm. It's an '84 Lotus frame. Then I looked at an '84 Miyata frame and that was 128mm.

During the transition period a lot of frames were spaced 128mm. Especially if the same frame was used for multiple models. This allowed higher models using the same frame to use 130mm drivetrains and lower models 126mm. 1984 seems a little early but maybe it was respaced somewhere in the past.

At any rate, no bikes in 1984 would have been 130, and certainly no freewheel road bikes.
Just because a bike has the dropouts at 128 doesn't mean it isn't nominally still 126. OLD is determined by the hubs. Factory might have fudged it a bit, or somebody else spread it to make it easier to get the wheel in.

Somewhere on his blog, Dave Moulton mentioned that he was building all his frames to 126mm when he hung up the torch in 1993.
