So I just finished fixing up a 92 (I think) Giant Yukon. Nothing real top of the line, but a solid bike, and will make a great commuter for someone.
And I noticed this weird braze-on/nub on the non drive side chain stay. Never seen one before and can't even imagine what it might be for. Any ideas? I thought it might be something to do with the quick release lever, but the lever doesn't even touch it.
