Internal Hub Advice
So, first time poster, hope this is okay location:
I have a Raleigh folding bike which happens to have an internal rear hub. It's been working great for some time but I got stuck in the rain the other day and the bike got really soaked. Since then the hub has been performing badly, chain skips a lot, shifting doesn't happen quickly, or sometimes not at all. All kinds of problems.
My guess is an internal hub is complicated enough that I shouldn't start messing with it. But I don't really want to pay a fortune to a bike shop to check this out. But my googling has brought me very little in terms of how to fix an internal hub....
A few questions:
1) Should I just suck it up and take it to a shop?
2) Is there a pretty basic - "typical things that go wrong" with internal hubs website I'm not finding that might help?
