Apparently, in 1980, Raleigh released a Special Edition Chrome DL-1. Not only is it chrome, but it appears to have come with a Brooks B33, nicer fender stays, front and rear powered lights, a full chain case, a Raleigh logo bell, and a front mud flap. Was that rear rack stock? It's a real looker!

If anyone has any information or literature on this Special Edition bike, I'd love to learn more! If anyone has one of these bikes for sale, please contact me :D
