THIS IS ORIGINAL 1980'S SUGINO CRANK DUST CAPS I BELIEVE, THEY ARE COOL YELLOW COLOR. THIS IS THE SAME PANTONE COLOR THAT IS USED FOR SUNTOUR VX AND SUGINO MAXY CROSS CRANKS. THEY ARE NEW AND NEVER INSTALLED. THEY ARE EARLY / MID 1980'S I BELIEVE. THEY ARE NOT METAL, FEEL LIKE HARD PLASTIC AND I DO BELIEVE IT IS PAINTED NOT ANODIZED. I BOUGHT OUT ENTIRE WAREHOUSE FILLED WITH BMX PARTS AND THERE ARE TONS OF SUGINO ITEMS IN THERE.
