Old (Antique?) 9-Speed Bike
When I was a kid I had a book called "The Boy Mechanic" published by Popular Mechanics. For some reason I just recalled one project to build a "9-Speed Bike". I seem to remember it involved grafting a three-speed freewheel onto a Sturmey-Archer three-speed hub. I was wondering if anyone else remembers this. Sounds like something Sheldon might have built just for fun. jeverett3ATearthlinkDOTnet http://home.earthlink.net/~jeverett3 |

Sounds like something Sheldon might have built just for fun. I did indeed, starting when I was in high school. Not sure what you mean by "just for fun" this was a pretty practical setup back in the day. Made it possible to have a wide range of gears with close jumps between. I had my Elswick Tour Anglais set up as a 12 speed in 1959 or '60 (4-speed Sturmey-Archer hub, 3 sprockets, Benelux Mark VIII derailer. My first home-built tandem, about the same time, was a 9-speed (3 x 3) A year or two later I had my Elswick Lincoln Imp built up as a 24 speed, 3-speed hub, 4 sprockets, 2 chainrings. I didn't learn this from a book, but I had excellent guidance from Ed Townsend of the Bi-Ex in Cambridge, Mass. My O.T.B. has had various gearing setups. When I bought it, it was an 8-speed derailer (4 x 2) then later a 10-speed derailer (5x2) then a 30 speed hybrid setup (3 speed hub, 5 sprockets, two chainrings) and currently a 63 speed hybrid (3 speed hub, 7 sprockets, 3 chainrings.) My most recent home-built kidback tandem was a 54 speed (as above but only 6 sprockets, 14-36 (the 36 was originally a TA chainring) My kids' BMX tandem is a 6 speed, 3 speed hub with two sprockets.

The kit, from Cyclo, included a rear changer, pretty aluminum downtube lever and full-casing control cable, extra chain links and either a two or three cog assembly to snap on your Sturmey driver. They were very cheap and went through periods of popularity as a dealer add-on. -- Andrew Muzi www.yellowjersey.org Open every day since 1 April, 1971 |

Nothing exceeds like excess. The use of the older Sachs/SRAM Spectro 3x7 hub for 63-speed drivetrains (and the newer 3x7/8/9 SRAM DualDrive for 63/72/81 speeds) in combination with a triple crank is not uncommon on recumbent bicycles that can use both lower and higher gears than an upright road bike. On my heavy but aerodynamic bike [1] the 3x7 hub provided two (2) very useful extra ratios at each end of the range. There did end up being about 40 near duplicate ratios, however.
