If you couldn't find one of those, another option would be the Schlumpf two-speed "mountain drive" BB, which might work with a fixed gear: http://www.sheldonbrown.com/harris/schlumpf.html Nope. It can't withstand significant reverse torque. -- David Damerell Kill the tomato! |

Or use a double chainring and two sprockets (should be able to screw two track sprockets onto the long thread of a 6/7 speed freewheel hub). 42x15 and 38x19 for example gives 76" and 54" gears with no change of length, and you could probably arrange a perfect chainline on both combos with a bit of shimming. You might even be able to change gear without loosening the rear wheel. change gear without loosening the r.wheel? that means a pretty loose chain. certainly looser than i would feel good running fixed. |

Do what the old guys did. Use a double sided hub. Put a small sprocket
on one side and a big one on the other. When you come to a hill. Get off and turn the wheel around. -- See some Bikes At: http://home.earthlink.net/~wm.patterson/index.html Class and Helicopter http://www.calpoly.edu/~wpatters/ Reply to |
