Beginner derailer question
Hey everybody, Ive been working on some old bicycles for the past several days non stop and I love it. Im learning lots about bearings and what needs to be greased (and what kind of stuff is beyond that, like 50 year old chains)
Im working on 3 bikes. A Raleigh Rollfast, a "mainliner" womens bike, and a schwinn continental. They are all 30-50 years old I believe. I am doing well but on the schwin Im having trouble with the derailers. I understand their function fairly well and Ive got them working well enough to where with the new cables they will shift back and forth to the highest and lowest position with ease. The highs and lows are set to what I think are correct positions. What I am having Trouble with is.... getting them to stay in a position? What I mean is, I move the shifter, it pulls the cable, moves the derailer over, chain gets moved, and them when I let go of the shifter it springs back because of the tension on it and the chain and derailer go back to their original positions. Is this a cable tension issue or whats the deal? I feel like this is a beginner question because Im pretty positive the bike is fine. thanks !
