Re: [RBW] Re: Drag in non-direct gears on SA AW: noticeable?
The numbers imply a likely ring and cog combination and the standard AW ratios. Yes, I think more and more that the S3X + fw is the right choice.

The part of your question I don't understand is the specific numbers you give. Wouldn't those vary, depending on chainring and rear sprocket? I've got sprockets in one-tooth increments from 16 to 21, and I think they go to at least 22... That said, assuming you don't already have an AW, the SX3 and freewheel sound like a good bet for what you want to do. Nick W.

For both the reasons Eric mentions -- direct in high, sturdier mechs -- I am leaning toward the S3X with a freewheel. Too bad no one makes a 3sp hub gear that gives you direct in high, a 15% reduction, then a 30% reduction -- is that even possible given the inherent limits in epicyclic gear trains?

Re: [RBW] Re: Drag in non-direct gears on SA AW: noticeable?
That's the point. A direct drive #2 gear with a 33% increase to high, as with the AW, leaves you -- at least, it leaves me -- with a high gear that is for practical purposes of no use, and a higher low gear than I would like. Now that would be no problem if indirect gears on the AW had minimal drag (whence my original question), but the consensus seems to be that, even with the relatively simple AW, they will cause more friction than direct. 70 as a direct high, as given by the S3X, and two step downs of 25% each, is a much more useful combination to me than a 70 middle, a 52 low, and a 93 high.

Now that would be no problem if indirect gears on the AW had minimal drag (whence my original question), but the consensus seems to be that, even with the relatively simple AW, they will cause more friction than direct. Absolutely, definitely the case, based on my 5 years' daily riding an AW. And I agree, high can be absurd: not only too high, but so much internal drag as to be minimally useful. One thing that helps is to change the sprocket so as to bring the gears down a bit. On a DL-1 70ish was too high for a normal gear anyway, so bringing it down to the mid 60s made it better, also made the high a bit more usable. Clearly a 25% increase for high and a 30% decrease for low would make more sense, but that's not how they're made. The 4-speed FM would probably suit you a lot better. For a 26 wheel, a 48T chain ring and a 18T sprocket you get: Low - - High 46.2 59.4 69.3 78.0 All eminently usable gears. Direct drive is 69.3. Make it a 19T and you get Low - - High 43.8 56.3 65.7 73.9 That pretty much covers most people's preferences for a cruising gear, and either way the high is nice but not unreasonably high and the two low gears are welcome. .67, .86, 1.0 and 1.13 for the gear ratios. Don't know why they ever stopped making that one. It makes a whole lot more sense as a usable drive train than the 3 speeds ever did. -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.

Re: [RBW] Re: Drag in non-direct gears on SA AW: noticeable?
Thanks, Scott. I'm not sure this serves my purpose. First question: how is drag in the non-direct gears? If greater than in direct, it's no better than the AW. If not appreciably greater, then I'd want to run 3d as a cruising gear -- ~70; in which case the drops to 2d and 3d aren't big enough. So, how is the drag in non-direct gears for AWs and other SA 3 speed hubs?

So I would arrange things so that the 33% augment in gear 3 would give me roughly 70, so that 2 would be ~53 and 1 ~ 39. But I don't want any additional significant drag -- have read the recent BQ. But the AW, now: that one is so simple that drag ought to be much less than with a more complex geared hub, no? Did Berto test this somewhere? Any advice welcome.

Re: [RBW] Re: Drag in non-direct gears on SA AW: noticeable?
Sheldon's article says drag in the SW is due to thick cantilevered pinion shafts - the AW reduces this effect by using separate stepped shafts On Sunday, August 18, 2013 9:19:34 PM UTC-5, Patrick Moore wrote: Thanks, Ron. The 48 t would give the ratios I want with a 17 t cog. What about the *drag*? -- You received this message because you are subscribed to the Google Groups RBW Owners Bunch group.
