Emblem bikes that I have seen do have some peculiar parts. The
crankset may have oversized threads and cones; the sprocket drive pin may be offset 2 inches.
They are an odd size and challenging to obtain - just something to keep in mind with any disassembly, repairs, refurbishments, or replacements.
The headset also has unique styling, (but I'm not sure if its dimensions are special).
Also, we see 2 master links - something that might be investigated, as to the need, or cause.
