I have recently inherited a 1983 Raleigh Record, all original parts that I can tell. It's in decent shape and my wife would like it as a second bike. First off is this rear derailleur:
A Suntour U? I can't seem to find any information on the Velobase page about it. Anyone know? Is it worth keeping, or switching to something like a Shimano Deore? (I have an extra one is why I ask).
More general question:
When fixing up old bikes like this, is there a good guide to knowing what can (er, should) and can't be replaced? Should I replace the bottom bracket with something like a new cartridge unit? How does one know what to keep and what to trash?
