They'll make good anchors for your boat!
True, in many cases, but there were a couple of nice old CCM road bikes offered in the fifties, sixties and seventies. My 195? CCM Westonia is a decent old road bicycle, although nothing terribly special. But my
mid seventies, CCM "Tour du Canada" is a high end road bike with full Reynolds 531 tube set and Campagnolo forged drops. You must be a wealthy person, to use such a bicycle as a boat anchor.
