I rencent aquired an AMF Roadmaster 12 speed bicycle. It features center pull dual pivot dicomp brakes and levers, The rear brake lever is on the left side of the bike and it has japanese made aluminim rims and the high flange hubs (can't find a name). The rear derailer is a shimono titlist GS. The front derailer just says Thunderbird on it. Both derailers are drilled with presumably from the mid 70's weight saving craze. Shimano shifters are on the stem.

The frame is awesome in weight and will climb these steep hills around my house like no one's business!!

Any information would be very helpful.
