However, if you're miles from the nearest bike shop, replacing the cog may prove a little difficult. So here's an alternative method.

You have to be able to dissasemble the cogset to do this, so if all your cogs are riveted together, you're out of luck. If they can be seperated, do so, and find the one that's causing the trouble. Usually it's one of the smaller cogs. Remove the offensive cog , then put it back on again, "inside-out". That is, the side that WAS facing out (towards the frame) will now be facing in (towards the hub). Reassemble the cogset. the skip shold magically dissapear!

The reason this works is because only one edge of the cog teeth gets worn. the edge the chain is pulling on. The other side is hardly touched. When you turn the cog around, the chain pulls against the untouched edge. It's almost like getting a new cog!

NOTE: If you have the old style screw-on small cogs, this, of course will not work for the threaded on cog, but it will for all the others. Also, I haven't had a chance to try this with any of the "hype"glide style cogs, but I don't see any reason why it shoudn't work. However, I don't know how it will affect shifting performance, as the "handicap ramps" will be on the wrong side. If any of you have the chance to try it with these cogsets, please drop me a line and let me know.
