Fixie frame with vintage 126mm wheel
I've made fixies/ss out of vintage bikes, some with 120mm (5-speed) spacing, some with 126mm (6-speed) spacing. I've used flip-flop hub/wheels and I've used 6-speed wheels with a ss freewheel. But I've never had a fixie/track frame until now. Someone gave me one missing its rear wheel.
So, I'm thinking of cold-setting the frame to 126, and using an old 126mm wheel with ss freewheel. Seems reasonable with maybe a sub-optimum chainline.
Thoughts? Warnings?

Could you remove 3mm of spacers on each side to convert the existing wheel to 120mm? This seems a better approach in the long run.

While I'm not afraid of cold-setting a frame if absolutely necessary, I'd try very hard not to if possible! There is always a chance it will end up badly.

I would swap out the rear axle for a solid axle and space it to whatever you need.

someone gave me a wheel that measured about 124mm. I spun on a 17T freewheel I had in my spares and squeezed it into the dropouts with little effort. It was centered between the brake caliper, and the chainline wasn't bad either. It was as easy as that. The bike felt great and the gearing is about ideal for me, 46x17.
