When do the frame rear standard changed from 126 to 130?

Shimano came out with 8-speed in 1988, it started showing up in the retail market late in 1989. It was a bold move to go against the 126mm standard, so the 8-speed Dura-Ace hubs had a rounded section to the left side locknut which was to allow you to jam the wheel into a 126mm spaced wheel. Campagnolo at the time was still running thread-on freewheels. It was a simple task to replace the axle with a longer one, but the last generation of 8-speed freewheels were a disaster because the last three cogs were unsupported by the bearings. By 1990 Campagnolo also had a freehub design which included this lettered chart that drove most people who tried to use it to drink - this is how our very own Boston Drunk got started, at least that's the rumor...

All road 8-speed freehubs are. By freehub I mean the rear hub that has the ratcheting system built-in with some sort of spline body to hold cogs. The older style thread-on freewheel hubs could be changed from one to the other with a few spacers and a new axle. 8-speed was a problem with the older hubs for a number of reasons. The axles were unsupported and tended to break at the threading which acted as a stress riser, the 8-speed freewheels sucked, and spoke tensions were very uneven.

It's easy to go from 126 to 130, just not the other way around. Just get the longer axle, add 4mm of spacing on the left side and redish the wheel.

No, plenty of 8-speeds were designed in 135.
