53 gears?
A while back I thought I saw a webpage that was somewhere, and I
thought it mentioned a bicycle with 53 gears or something like that! Does anyone know about this bike? It's to settle a bet between me and my dumb brother. Ken |

Sheldon Brown has a 63-speed: http://sheldonbrown.org/otb.html Fifty-three would be a bit of a trick - that's a prime number, so it would have to be 53 sprockets on one axle. |

Ken I think that Sheldon brown had something like that, I think it was actually 63 it was a 7 sprocket rear, a 3 speed Hub and a 3 speed chainring... 7 x 3 x 3 is 63. Considering that you can now find 12 speed hubs, 10 sprocket cassettes, and 3 sprocket chainrings, the maximum now would be closer to 360 gears. To overstate the way over obvious, shifting would be a bear..... Does this shifdt give us 247 or 162? W |

Yeah but that link is the one that I remember seeing, I just couldn't
remember exactly how many gears it had! My brother think it's stupid. Well I just had to find it to prove to him that it does exist(sp)! Ken |

Ken I think that Sheldon brown had something like that, I think it was actually 63 it was a 7 sprocket rear, a 3 speed Hub and a 3 speed chainring... 7 x 3 x 3 is 63. I believe this is right. By the way, a 53-gear bike would be difficult to arrange, since 53 is a prime number. Considering that you can now find 12 speed hubs, 10 sprocket cassettes, and 3 sprocket chainrings, the maximum now would be closer to 360 gears. Well, you can't mate that 10-sprocket cassette to a 12-speed hub, anyway. But it's worse than that. There are 14-speed hubs (Rohloff), 4-chainring cranks (for tandems), as well as 2-speed internal gears for cranks, though I don't think you could mate anything like all these together. The Rholoff hub seems to have a threaded sprocket, unlike the Shimano which is a splined sprocket held on with a spring-clip. This might mean that the hub could accomodate a freewheel. Let's be conservative and only assume you could squeeze in a 5-speed freewheel. That would allow 14 x 5 x 4 =280 gears, but a more reasonable estimate would be with a double chainring, still giving 140.... -- David L.
