I just picked up an old bike to clean up and move on.. hasn't been ridden in a while and the chain is pretty rusty. Can I salvage it with eg WD-40 or would it not come up well enough to bother? It's 7 or 8 speed (Tourney RD), nothing fancy.
If the links are still all moving reasonably freely it should come back to life OK. If any links are rusted to the point of sticking together then it's not really worth the effort of trying to resurrect it.
Thanks Dunky.. the chain cleaned up a bit with WD40 but there's a stiff link. A 7-speed chain shouldn't cost very much I imagine (you can get them at K-Mart right?). The brakes rub too cos the wheels ain't quite true, story of my life
