Restoring an original 1964 C15t GP It has conical hubs now with a 60 tooth 428 sprocket.
Does anyone know where I can get a new rear sprocket ?
Cheers

Easy to make, but are you willing pay the price. Sprocket blanks of gone up in price in recent years. Also the range has decreased. PES can make most sprockets, even if they have to cut the teeth.
