(BTW I looked into the seat tube and there is zero rust visible inside).
2. What can I do about these rust spots?
3. Should I do anything about them?
4. I bought the bike to ride it.
5. Also: can anyone explain what is most likely to have caused this issue?
6. One other question: There is no other rust whatsoever on the bike except for this weird raised accumulation of grime under the cutout for the seatpost clamp. It seems to have rust as one of its ingredients,
Thank you, I am really enjoying this forum. I did search around for rust info before posting but the oxalic acid baths etc. seem like overkill given my situation.
I'll try but without pictures, I'm guessing:
1. I doubt it's rusting from the inside out, perhaps it's just where moisture was allowed to accumulate
2. Dab the are with OA, or use a small tooth brush and Barkeepers to remove the spot and touch up with paint
3. Better idea, unless #2 makes you feel better
4. Then thats what you should do. The frame will most likely out live you anyway
5. a lethal combination of moisture, oxygen and steel
6 since the seat post is free from the tube, I'd think a mixture of road grime and rust hardened over time
IMHO, just clean it, lube it and ride it. Many happy miles and welome to C&V
