I just bought a '87 Santana Sovereign tandem. Much of the drivetrain has been upgraded; it now has an 8-speed shimano freehub, an MX cassette, and new Deore front and rear derauilers. However, it still has the original Suntour Stronglite cranks, with what appear to be original 54/49/32 chainrings. All of the rings are badly worn, especially the middle one. Is it still possible to buy these chainrings? If yes, can someone recommend a source?
Thanks for your help!
