Dustin Gyger October 3, Common Fixes for Skipping Chains The most typical recommendation for fixing a skipping chain is to add tension to the rear derailleur.
Step-by-Step Instructions Put your bike in park and manually pedal forward using your hand or foot until the derailleur has been adjusted down into the smallest cog. Press the shifter once to see if the chain moves up a gear.
If nothing happens, you need more tension. Now you want to turn your barrel adjuster all the way in by twisting it away from you. Not sure where to find it? Lubricant that is as thick or slightly thicker than your chain lube will work best. If you have just added new lube and it is too thick you can flush it and apply a thinner lube or you can add a thinner lube and work it into the body until it spins more freely.
If water has frozen inside the body: If you have ridden in the rain or washed your bike recently and the temperature is below freezing, you may have water freezing the pawls shut in the cassette or freewheel body. A quick fix is to get the bike warm.
A hair dryer can speed up this process. Sometimes this heat is enough to evaporate any moisture that may have accumulated inside the body. If the problem persists or you want to make absolutely sure that there isn't any moisture in the body go ahead and flush it with solvent and add fresh lube.
This should displace any water that has accumulated remember, oil hates to be around water and vice versa. Stripped cogs on the body of the freewheel or cassette: Occasionally a cog will spin on the body because it has stripped out. This is a more common problem with freewheels than cassettes, but it does happen every once and a while to cassette cogs. Solutions are to replace the offending cog and hope that it meshes with your chain.
If it doesn't mesh, it will skip and you will need a new set of cogs and a new chain. Replacing all the cogs and the chain might not be a bad idea for cases of this nature because this problem may be an indication of a well worn drive train that will start failing piece by piece. My chain skips only when I go up a hill or put a lot of pressure on the pedals. The Cause of the problem: This is a common occurrence when one component of a drive train has just been replaced or a drive train has been used so much that the chain skips over the top edge of the cog teeth.
Every time you ride you make your chain longer due to the force of pedaling. A new chain will measure exactly one chain rivet or pin for every half inch. A chain that has thousands of miles ridden on it will have pins that almost match up on every half inch mark, but by the time you get to twelve inches the twenty-fourth pin will be around twelve and one eighth inches.
As a chain stretches it wears the leading edge off of the cogs and chain ring teeth. Mixing a new chain with old cogs is a problem because the new chain usually doesn't mesh with the worn gears and skipping results.
Usually skipping presents itself in your favorite gear, as this is the gear that wears out the first. Other problems associated with a worn drive train are bushings coming out of the chain, bent cog or chain ring teeth, and individual teeth breaking off of cogs or chain rings.
All of these problems can cause a chain to skip while under pressure. On the assumption that everything was fitted properly, my first guess would be chain is too long, my second would be that derailleur adjustment is required, but this guess doesn't specifically fit your description of "hard" pedalling.

How can I make sure? Improve this question. Take your pick. Did you remove any links from the new chain, or did you fit the whole thing as it came in the box?
The chain could be slipping due to natural weakening of the chain. Over time, the chain will stretch out and a loose chain means more slipping when pedaling hard.
