I picked up a free old "Free Spirit" 10 speed and I want to make it into a fixed gear. The wheels that I've got are 26" and they're VERY heavy. I want to pick up a new set of wheels but I haven't been able to find any.

Is my best option to pick up a set of 650c track wheels? Or do I have any other options? I'd appreciate any advice, I'm roadie looking to expand my horizons.

Thanks,

Doug
