There is one essential and one desirable: Essential: horizontal dropouts. Desirable: either a high bottom bracket or slightly shorter cranks. |

You can pretty much run a fixed gear in any bike frame, even one with
vertical dropouts. Here is a link to a newsgroup which can help you:- http://lists.davintech.ca/mailman/listinfo/fixed-gear Hope this helps you.

There's only one detail to be concerned about- does it have vertical or horizontal rear dropouts? If they're horizontal, it's an easy conversion, if vertical it gets somewhat more difficult. I wouldn't bother repainting it unless it's some sort of restoreable collector's item. Just ride it ugly. Good reference: http://www.sheldonbrown.com/singlespeed.html Jeff |

Frame suitable for fixed wheel bike?
I've been looking for a cheap frame suitable to build up into a fixed wheel
bike. I've been given an old Kojima Condor with downtube shifters, which I know nothing about. The frame is marked 'Tange 900' double butted. I think it’s a lugged steel frame. Does anyone here know if this is a reasonable frame to dress up into a fixed wheel bike? I've googled but can't find much info. The other bits of this bike show signs of neglect so I'm thinking if I start with this frame it will need to be cleaned up, repainted and pretty well have a lot of work done. I want to use a fixed wheel bike for fun and training but also as a build project to learn more about how to do assembly and get some basic know how. Any help about the frame is welcome.

On another note, is there any reason to NOT use the 39 tooth inner ring as the chainwheel for a fixed wheel conversion so long as the appropriate rear cog is used? I'd like to not blow the budget on this project while I build and learn! Thanks Nothing wrong with the 39t chainring. I'm running 48/17 chainring/cog combination. At times this is a bit much for me - even living in relatively flat Toronto. Regarding the relation between chainring and cog: I prefer a combination whereby the number of chainring teeth are not evenly divisible by the number of teeth on the cog. (For instance, I avoid a 48/16 ring/cog setup.) This more evenly wears the ring, cog and chaing as, with each wheel revolution, the position of the cog vis-a-vis the chainring changes, allowing different cog teeth to bear the force of each downward pedal stroke. luke |
