I just put a new chain on a drive train with a used cassette. The combination is Shimano XTR 9-speed with an 11-34 cassette on a touring road bike.
Since doing this I have noticed that the chain occasionally skips when in the smallest 3 cogs. There doesn't seem to be any consistency about when the skipping occurs. It seems to occur about as often while standing and putting considerable force on the chain as when sitting and putting minimal force on the chain.
If the cassette was worn I would expect it to skip more while standing and not at all while seated. Is this logic correct? Anyody know what is happening here?
On the same vein is there a good way to measure the wear on the smaller cogs of a cassette? How do you know when it is time to replace a cassette?

I've had this and fixed it by fooling around with the chain wrap adjustment on the jockey wheel. -- PeteCresswell

Stiff link perhaps? (Or funky quick link?)

My rule has always been when it skips with a new chain -- although only experience with that has been on mountain bikes...and it's the BIGGER (grannier?) cogs that wear out on me!
The above is an article by a man from Palo Alto who rides a lot.
You probably waited too long before you replaced the chain and now need to replace the cassette as well. (Did you save the old chain? You might want to put the old chain back on the bike.)

When they skip with a new chain. If you are skipping in all chainrings, than it's likely the cassette. If you are skipping on the 2nd chainring, it could be the chainring.

Here is another thought. The weather was cold (at least for NC!) in the low 40s. The chain is new and tight. But the kicker is that the chain is lubed with White Lightning which tends to get stiff when cold.
