Bicycle Drivetrain Rebuild

Bicycle Drivetrain Rebuild - chain, chainrings, cassette, bottom bracket

Replacing the drivetrain on my 27 speed Giant Perigee. Chain, outer and middle chainrings, rear cassette and SM BB-70 bottom bracket. Also some explanation of chain wear, also called chain stretch.
