I can remember reading about 9 speed bikes in the early 80s but nobody would believe me and I was never able to find where I'd read it again.
Did the idea ever catch on at all? In a way it's better than a ten speed because it doesn't have two gears you aren't supposed to use.
I think the idea got lost in the noise! It seems that folk had been putting 2 or 3 cogs onto SA 3 speeds for a while (Cyclo made the bits, I believe), then in the late 50s derailleur offered more gears and were seen as"desirable". By the time SA started working up from 4 gears it was too late for them to catch up, as well as being the period when the firm was sold on and went abroad. There is lots of history on all this, it was a quite cheap and mechanically sound way of offering more gears, but I don't think any manufacturer offered bikes with hybrid systems. Unless I am wide of the mark it is only now that hub gears are starting to make a comeback.
The frame had been made for a rear rerailleur with one braze on, and the dropouts were just wide enough to take the AW hub with a longer axle fitted to allow for the three speed screw on block.
What I don't know is whether my ratios will work well and how many of the nine will be usable, I'm not that clever with numbers so I shall wait and see. The cogs are 16, 19 and 22 teeth, if anyone can work that out? I suspect it will give me at least couple higher and a couple lower that the normal AW ratios. Not had it out yet, but I will let you know.
Just checked the old AW cogs in the bits box. Both the ones I have are 18 teeth. That makes the gearing 46/16 46/19 46/22 as against the normal SA 46/18 for a 27" wheel. That should give me three gears a little higher then the AW ones, and six a bit lower. I am looking forward to having a higher top and a couple more in the mid lower range for hills!
