Really? Did a search to find out what this is, and confused as this is a men's frame, but in one of the boxes of mystery parts, there were short sections of twine-like cord, so... ? Apologies for my ignorance here-just getting into this. Every bike I’ve done so far, I started from the rough, and documented each stage of disassembling with photos, making it easy to reassemble, invaluable in my previous restorations of classic cars and motorcycles. Cheers.
