shwinn world sport, unknown year
well i've had the bike for a long time, its a red shwinn world sport (duh lol). mainly i just do a lot of city riding, but i haven't rode in a good 3 years. so i got to checking my bike out and decided i want to fix it back up and make it ridable again, because i literally haven't rode it in 3 years, and i miss the fun and excersize. the reason i put it on the rack about 3 years ago was because i crashed it pretty good and it broke the derailer. i'll get a few pics and post them in a little bit. but anyway, everything on it looks to be pretty good other than the derailer issue.
the derailer is a shimano rd - z501. the part of the derailer that broke is the ear that holds it, that uses the axle bolt to mount . mainly what i wanted to know as far as rear derailers go is if i can't find a z501, what other models would work, and what would i have to change to get a different derailer to work? i also have another shwinn, its a varsity, but the derailer is very different/mounts a little different comparing the 2.
the wheels could probably use a trueing up as they're a little "wobbly" when they spin, not too bad tho. the rims seem to have surface rust (very little) i've read some where you can re polish them?
other than adressing those issues i'm about to take it apart and repaint it and put new decals on it. what else should i make sure to check out and fix before riding it again?
