My Raleigh Grand Prix, circa 1978, was Made in England (of course!) is a gorgeous green/bronze colour and has Suntour derailleurs, front and back. I adore it!
..and what I like about those Grand Prix’s is the standard BSC thread.. good luck with your velocette. My International has certainly lived it’s 40 odd years of riding.. replacing tired components (sans FD) has transformed the riding experience.. NOS crankset on its way.. cheers, Matt from Australia.
