What makes a used frame bad for conversion? (outside of the obvious)

Im looking for a step in frame for my girl (its what she wants) to convert to SS...but outside of the obvious (cracked/bent frame, vertical dropouts) im not sure what else I should be trying to avoid

is there anything else I should be looking for??

ashtabula (one-piece) cranks, vertical dropouts, poorly fits the intended rider, french threadings (unless you want to spend time finding compatible parts), unnecessarily heavy and clunky (schwinn varsity), stamped dropouts, high tensile tubing.

Basically, any bike that didn't retail for more than $300 at one time or another.

If you wouldn't ride it as a geared bike, don't bother converting it.

What to look out for: Huffy, Murray, Pacifica, Next, Roadmaster.


I've used the one-piece (ashatabula) cranks before without problems, it is true that you will find these on cheaper frames though.

I like to have room for a slightly wider tire than some of the older racing bikes. I have a Peugeot and have to deflate the tire to remove the rear wheel. Not a huge deal, but not ideal.

I like to be able to ride on anything and not worry about curbs and cracks, so I ride a slightly fatter SOMA tire.

I like the peugeot because it has virtually no braze-ons, so it doesn't look like a frankenbike when you are done. When I rode it SS, I had nice clips for the rear brake. When I removed it, clips gone, brakes gone. The only residual is the holes for the centerpull brakes. No bosses for shifters, bottle, cables, etc.

I also like 120 spacing in the rear for track hubs. Looks clean.
