The best recommendation for fixing a skipping chain is to add tension to the rear derailleur. When your bike chain starts to skip, you could have problems switching gears and navigating your two-wheel chariot, and the most common culprit is a loose cable. If the chain skips under pressure, it is most likely worn; if you have replaced it recently, you are waiting longer and have worn your rear cassette gears. They don't mesh with new chains. If the chain skips every third or fourth pedal revolution, you probably have a tight or bent link. My gears won't shift smoothly from one to the other, making a lot of noise. That's why my mountain bike chain skips.
