I managed to acquire a Shimano Crane GS the other day, and I'm wondering about the details of this shifter. This is the rear long cage model with the round holes drilled in the front chain pull arm. I remember them being standard equipment on older touring Schwinn Paramounts.
It appears to be a horizontal parallelogram design, but not a slant parallelogram. Was this piece made before Suntour's patent expired? When did Shimano stop making Crane derailers.
What size freewheel with the Crane GS handle, and how much chain will it wrap? Does anyone have any experiences to share about the derailer's performance?
Thanks
