I just purchased an older 12 speed Schwinn 'Super Sport' from a friend who had it stored as a second bike but has not used in quite some time. It's been awhile since I last rode a bike and left the gear setting where it was when I bought it. Today I took it out and started shifting to get the feel. Now I have a problem. When I try to use the right shift lever to move chain from smallest back sprocket to a larger one for climbing hills, the lever doesn't stay in place but moves back down thus moving the chain back to the smallest sprocket. I have to manually hold the lever up in order to have chain stay on larger sprocket. Any ideas? Thanks!
