But I think the first 6-speed freewheels were in the late 60's, so as the mid-70's progressed you saw bikes opening up to take those. Ultra-6 came way later than regular 6, so it wasn't a case of "expanding ultra-6."

So Ultra 6 was more of a bandaid for the old 120mm standard to make those bikes competitive with the standard 6 speed bikes? That makes sense.

How were 6 speeds used in the '60s before 126? Just too much dish and lots of broken spokes?
