I have a circa 1987 Lotus Odyssey with a Biopace triple chainset. They look like aluminum, but I'm no expert. The middle chainwheel, 38T, 5 bolts, 110 mm BCD, has worn teeth from decades of mis-shifting, and the chain slips when I pedal hard. So I'm looking to buy a replacement. This is to use, not to collect dust, so the teeth need to be in good shape.
Well, some of us who posted on this thread are still around. Heck, it's only been 10 years- still a youngster for a zombie thread.
I bet that those boxes of take-off Biopace chainrings are still at Euro-Asia Imports. That won't be much help to you- Euro-Asia only sells to select bicycle shops and it would take some motivation for them to dig out those old Biopace chainrings.
