I have some old ESGE fenders (I suppose that would be SKS now). They are the chromoplastic commuter versions. P55s.
The bike came with a rear light mounted on the rear mudguard and a rear tire-friction side mounted dynamo. The positive current traveled by a wire from the dynamo to where the mudguard attaches to the frame behind the crankset. From there the current travels from through the aluminum side strip inside the mudguard to the rear light.
The mudguard no longer conducts.
If I were to get a new mudguards, would the come with the hardware to connect to an from the aluminum strip in the mudguard? If not, can the hardware be purchased separately?
