There is a wonderful resource for fixed-gear riders who use vertical dropouts: The Fixed innovations web page, created by stalwart fixed-gear rider and creative guy Eric House. Find it at

The part you need is his "FixMeUp" program, that'll tell you which combinations of chainring and rear cog will work with a given chainstay length, to get the gear ratio you want. The java form of the program ( is the coolest, works in your web browser if you have Java on your computer. (He has links to get your Java up to speed if it isn't) He also has a stand-alone program ( you can download and run on your PC or Mac, that doesn't need Java.

It's a bit complicated, and you need to measure your chainstay length very precisely, but he has excellent instructions - I'm just saying you may have to actually *read* 'em, however that may go against the guy code. Even how "stretched" or worn-out your chain is makes a difference in what gears will work, but his program deals with that too.

Check it out!
