I mean to change the parts to early raligh parts, those bikes shouldn't have plastic on them, i like keeping my bikes the period correct stuff on them but Plastic just cramps my style lol My DL-1 had one of them shifters on it, I put the other kind on it.
Regarding that cable, the reason it goes where it's going is because theres a pully wheel behind the sprocket, well should be, the early 70's models and years before that had it by seat clamp. most the time anyway, The pully on that one might not be adjusted proper making the wire run away from the lower tube, another reason I found was when the bikes where assempled some people made a mistake and ran it the wrong way and the chainguard gets in the way so they adjust it a alternative way. I know this because i've proberly owned over 250 of these bikes lol right now i think I have atleast 24 of them. by far my fav 3 speed bike.
The Raleigh sports is a bicycle that you can keep riding, despite never being maintained and sitting in all types of weathers, aslong as the tires hold air, even if they don't the bike will almost always be ridable. The 1939 Sports I have is a good example, it was hiding for such a longtime and rode like a dream once tires where aired up.
Obey The Raleigh! Get one for yourself!. Also highly modable!
