This stuff is inexact, so you often saw 5 speed spaced more like 122. The 6 speed could be a mm or two off the nominal 126 mm. The "Ultra 6" was a SunTour trademark and I do think they originated the design, but several others, including Maillard, copied it.

I believe SunTour did offer a narrow chain with the Ultra 6, but I never bought one. The SedisSport chains worked with no problem. Not sure I ever tried an older 3/32 chain like Regina Extra with an Ultra 6. Those I generally reserved for use with Regina FW's. Didn't shift as well as a SunTour/SedisSport combo, but more correct on Italian bikes.

Howard, Just in case no one else answers, 5 speed spacing was/is 120mm. Some 6 spee d freewheels were made a bit thinner between the cogs, allowing a fit inside a

120mm space. They were known as "Ultra 6" speed, and required specially spaced chains, IIRC.

Standard 6 speed spacing, however, is 126mm. Subsequently, Ultra 7 speeds showed up, fitting within the 126mm space, and then there were standard 7 sp eeds ... but all this drifts off topic.

I would like to ask a terribly naive question, except, of course, if you don 't know the answer, which I don't.Â

What is the rear spacing for the old style 6 speed bikes? I believe the newe r 8, 9, 10 speed are 130 mm.
