Actually they are original from what I can see, very little wear on the drivetrain, fact is I probably will not ride it too much, any least for now. Nice days only. Although now modified from stock I kept the parts it had from new just in case. Finding components such as the crankset and freewheel in almost like new condition is not all that easy, unless one likes to pay a premium in most cases. I have taken to liking and appreciating that unique 3 pulley Suntour rear derailleur.
