I recently replaced the original Pino bottombracket-freewheel with a new one.
On the old one the freewheel is an integral part of the bottombracket-spindle. It uses industrial bearings and a standard crankset (left and right).
It is not broken; I just wanted the newer style freewheel where the freewheel is part of the right crank and you can use a normal bottom bracket.
If anybody is interested in the old one, let me know. You'll only pay shipping costs.
It is in Holland.
