I recently bought a used On-one inbred 29er on ebay that was supposed to have a scratch on the top tube badly covered by messy paint. On closer inspection, and after peeling off some paint, the frame has a 15cm *crack* on the side of the top tube. The tube wall gives in with minimal force from my thumb. Is this wealdable in a trustworthy way? How about cost? The frame is DN6 cromoly steel.
BTW the ebay seller's ID seller is easterpark so beware. He told me he had broken a leg or arm riding just after the transaction and that makes me believe in Karma. I am also really bummed as after several upgrades I am broke and with no bike to ride.
