Alright, so I've got an internal Hub on my folding bike (Raleigh City 100) and also on my Mission Bike (local maker in SF).
Anyway, very few problems over the past year but both are starting to skip once in a while. Seems to be getting more common. The little white indicators are lining up just fine (not sure what the proper name is for that). So....
1) Should I be greasing the chain regularly on these bikes like a regular hub?
2) Might the chain just be getting a little stretched?
3) Should I be doing any other basic maintenance to keep these babies running smoothly?
