|Chain skip under climbing pressure||MrSteve|

|When I am standing on the pedals and climbing a hard hill my chain skips. Is this a sign of a worn chain, chainring? Where and how do I start my investigation? Thanks.|

|When that happens to me, it usually means my cassette is dead, and is worst when I put a new chain on an old cassette. I assume it's skipping in back, not the ring?
If you have another cassette, try that. If it does not skip, then that tells you something. If it does, then they both could be worn (which is entirely possible if you have swapped them out often, the same chain wearing both), or it could be something else.
If the rear derailleur is slightly out of adjustment, it could skip a little. It should be easy enough to adjust the cable a little and see what happens.
If you replace the cassette, do the chain, too, and don't rotate in that set-up another cassette that could be worn, or it will ruin that chain and then the new cassette. Cassette wear is contagious.

Truthfully, I am not sure if it is skipping in front or back at the moment. This morning in the rain is the first time it skipped multiple times on one climb. In the past few weeks it skipped only once on a few seperate occasions when under pressure. I will pay more attention to the location next ride. I think, however, that it may be a chainring skip.

|Things have to be VERY work before you'll get chainring skip. On the 39, you have 19 teeth engaged, vs. less than half that on the rear. In order for the front to be skipping and not the rear, that chainring would have to be severely worn.|
