"fixed" freewheel, variable gear?
But while thinking about it during a ride one day, I got to wondering if
anyone has tried fixing the freewheel (or freehub) but still having a cassette and multiple gears? So why is this a silly idea? Has anyone tried it? Suggestions for how to fix the hub? thanks, byron Apart from snapping off the derailleur, simply locking down the freewheel doesn't get over the problem of reverse chain tension unscrewing the freewheel from the hub. If you want a fixed wheel without a new wheel, there's an expensive converter which puts fixed cog and lockring threads on a shimano or compatible freehub, and a similar product is also available for threaded freewheel hubs. If you really want a multispeed fixed, you need to invest in some rare and very expensive retro parts from Campag or Sturmey-Archer. But why make life complex? Just rebuild your back wheel around a track hub and learn to pedal fast! Good and appreciated advice from everyone; thanks. I'll just build a single fixie and fly. |

Didn't one of the earliest shifting systems involve reaching back and opening the QR, then using a fork sort of thing to push the chain on to the next cog? Yes. Wouldn't this work on a fixie? (My interest is purely theoretical, I have no desire to actually try this, mind you. Probably, but it would be diabolical. The reason you opened the QR was to let the wheel slide forward and back to take up the chain slack. So you're suggesting releasing the QR, tapping the lever to shift the chain, then re-engaging the QR, but oh yeah, since it's a fixie, you can't stop pedalling. You know, there's a reason the derailleur was invented, -- Ryan Cousineau, http://www.sfu.ca/~rcousine President, Fabrizio Mazzoleni Fan Club |

I've been reading all the threads about fixed gear and am sold on the benefits. Can't wait to try one. But while thinking about it during a ride one day, I got to wondering if anyone has tried fixing the freewheel (or freehub) but still having a cassette and multiple gears? This would seem to provide many of the benefits of a fixed gear while still offering the flexibility to maintain cadence through gear changes. It also means that it might be possible to convert a bike to "fixedwheel" or "fixedhub" with no other drivetrain changes. So why is this a silly idea? Has anyone tried it? Suggestions for how to fix the hub? See the earlier post about a binding freehub body. The chain bunches up when you try to coast. Some riders who ditz around with tensioners, a fixed hub and vertical frame ends find this as well. -- Andrew Muzi www.yellowjersey.org Open every day since 1 April, 1971 |

[regarding multi speed fixed gears] 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 wow. what an idea. ive heard that there are still multi speed bottom bracket setups on the market. up to five speeds, did i hear? would these work for fixed gear? are they made for standard bb shells? very curious, anthony |

yan- Didn't one of the earliest shifting systems involve reaching back and
opening the QR, then using a fork sort of thing to push the chain on to the next cog? Wouldn't this work on a fixie? BRBR Yep, Earliest Campagnolo 'shifting' system, bring yer checkbook if ya find one and learn to play the piano- Why not just weld a freewheel together, add as many cogs as you wish and then stop to change the gearing, must have LONG dropouts for chain tension tho- Peter Chisholm Vecchio's Bicicletteria 1833 Pearl St. Boulder, CO, 80302 (303)440-3535 http://www.vecchios.com "Ruote convenzionali costruite eccezionalmente bene" |
