To my knowledge, this bike has all the original parts although I cannot tell you anything about it's history. One bicycle enthusiast told me the gearing system is a classic and would be sort after. I only replaced a couple of nuts and bolts to stop the mud guards from rattling. The gearing on this bike is brilliant, smooth and forgiving. The tyres will need replacing soon; the back tyre with a slow leak but lasts a few days. The dynamo works well, lighting the front and back lights. The seat is torn along half of one edge yet remains very comfy, in my standards. If you have any other questions, feel free to give me a call.
