Hey CRs, I have one only, black plastic stem cap off a 70s era Cinelli stem. Solid black with white C and wing,engraved and white paint. Not NOS but in very nice shape. The two little snap tabs are in great shape. All it needs is a stem with an empty 17mm hole. $5.00 at your door,or send me back some little doo-hickey you don't need. Dickey Greer West Monroe,La USA
