My eBay 1973 24" Opaque Blue fillet brazed Schwinn Super Sport was delivered today by FedEx, and I spent the afternoon stripping everything off the frame in preparation for powder coating. I've been curious about the actual weights of the frame, fork, Ashtabula crank, and kickstand for years, so I weighed them all.
24" fillet brazed straight gauge chromoly frame (no headset): 7.25 pounds
Fork (crown race removed): 1.98 pounds
Ashtabula crank/chainrings (with bearings, cups, locknut): 4.01 pounds (!!)
Kickstand: 0.83 pounds
I'm actually pleasantly surprised by the frame and fork weights.
