Crack in Aluminium Frame
I have a 1997 Giant alumium mountain bike (or as the US spell it 'aluminum'). I have a crack in the frame on the drive-side chainstay. It's at the bottom bracket end near the weld on that little support strut that braces the two chainstay arms together.
It's on the inside of the tube and slowly getting bigger. I am no longer racing this bike and now I just want to use it as a commuting bike. I've been told that if I got aluminium welded, it should be heat treated afterwards so that it won't fail.
This would be way too expensive so can anybody offer me any advice on how to repair the frame?
