Strumy Archer makes a 120 OLD version of their X-RF8 8 speed internal hub. It is a modern style hub with a rotary switch rather than the chain actuated gear shift. On Jun 20, 2023, at 9:50 AM, Arthur Mayfield <ajmayfi...@gmail.com> wrote:
I don’t know what the rear spacing is on the Quickbeams and Simple One, but my Frank Jones Sr has 120mm track dropouts. Finding a modern manufacture IGH with 120mm OLD has been a lost cause for me (and I build my own wheels). I’m sure if I pored over the possibles long and diligently enough, I’d run across one or a vintage AW, but it simply becomes easier to hop on another bike when I need the gears. I’d like to build a 3 spd wheel for my FJ, though.
One clear advantage of IGH over other multi-gear options on single speed bikes that I haven’t seen mentioned is the ease of riding with “good” fenders. I’ve tried using a flip-flop on my FJ with full coverage, aluminum fenders, and it’s not only a pita to do on the road (as well as time-consuming), but the rear fender could never be set up to fit properly to my standards. An IGH would make that a non-issue, at least until there’s a flat. Removing wheels from bikes rigged with chain tensioners on track dropouts “in the wild” for flats or other maintenance presents yet another nest of problems, with or without fenders. Overall, I’d be happier with a nice IGH. I could even get down to one bike 😝

In defense of the old 3 speed igh, the drag, at least for the old SA AW, has been tested at considerably less than that of much more complex, multi-epicycle internal gear trains with 7+ gears, and my experience (considerable with 2 and 3 speed SA hubs, only a little, but some with modern 7+ gear hubs) bears this out very clearly.
IMO, the simplicity and low drag (and lower weight) of the simpler multigear hubs makes them preferable, at least to me, to the more complex, draggier, and heavier ones.
I have a QR 17/19 Dingle wheel on my Riv 1999 fixed gear road custom and switching from the 76" to a 68" headwind gear is very easy, but I noticed that I downshifted much more often and readily with the 2 speed TC hub (76" direct and 66" underdrive), helpful when your direction into the wind or the slope of the terrain changes often. My point is not that you ("all y'all") should go get a TC -- last made in the 1940s? Mine is 1937 -- but that igh's do offer some benefits over manual "get off the bike and move the chain" shifting.
Personally, I perfer the external simplicity of a simple igh over multiple cogs or rings, and I prefer multiple cogs over multiple rings, again for simplicity and ease of use. AAYMMAWV.
I get back to that downgeared AW Schwinn: 69", 52", 39" which for a $50-total-expenditure beater including new 36 t chainring + shop labor (1989) proved to be very versatile indeed.
My orange Quickbeam came set up as a "2 speed" with 32-40-chainguard chainrings on a 74/110 triple (still has those) plus an 18t freewheel. I immediately made it a "3 speed" with a 17/19 Dos Eno freewheel. The chain is too slack for the 32/17 to work, so only 3 options: 40/17 (99% of my riding), 40/19, 32/19.I later added a 22T freewheel to the flip side of the flip/flop hub, which will work with the 32, but not the 40, so I have an extremely inconvenient 4-speed.
I rarely take it out of the 40/17, but the headwinds this morning made me wonder if I should have used the 40/19.
All of that was much cheaper and easier than getting an internally geared hub, and if I did go for an IGH, I'd get a modern 7 or 8 speed anyway.
