Found this beautiful frame thrown out in a dumpster. It surely needs restoration, but I noticed it has a dent about on the middle of the downtube. It is about 1 cm in diameter, and it would seem the former owner has already tried to fix the dent with clamps.
The tubes seem very thin-walled as the frame is very light. It has Columbus EL OS tubes. However I'm a light rider (65 kg) - should I worry about it?
