I have a set of HARO/Alex wheels with 14mm axles I'd like to use on an older bike. I'm not going to grind out/down anything. I poked around on google a little bit but haven't turned up anything. Are 14mm slotted axles out there? NOTE - -these wheels are temporary. I plan to put some era correct wheels on this bike, probably Tuffs, but it could be months so I'd like to get this bike rolling over the summer. So I don't want a lot of trouble or expense. Thanks for any info/suggestions/solutions/ etc.
