Got a bike given to me to fix up for my granfather to use around town. It is a Free Spirit 10 speed comfort type bike. Chain looks pretty rusty on it but I don't think there are any frozen links or anything. Is there a trick to cleaning the chain up and using it or is the only real option to get a new one. Thanks for any advice.
I've given a rusty chain a good soak in diesel with some success. But then again it is your your grandfather, so maybe you should pony up the 10 bucks to get him a new chain. I'm sure he wouldn't be happy if the chain snapped on him.
this has been the topic of recent posts. This might be one of the few good uses for WD-40. Apply to chain, wipe, ride for a spin, reapply & wipe. If the chain hasn't rusted beyond surface you may get it looking good, or at least ok just by getting it back in use with a penetrating oil, then a good chain lube.
WD40 works for a rusted chain. It is not a good lube and will wash off easily, so add some thicker lube when it is running freely.
If the transmission is worn, you may need to replace the chain and freewheel (rear cogs). For occasional use you can make do with a worn tranmission but for regular or extended cycling it is worth starting with a new, unworn setup. A new chain on worn cogs will slip and the chain will wear out more quickly.
