Chain Skip vs. Chain Slip

I have this other thread currently going on (http://www.bikeforums.net/showthread...-m-baaaaaaaack) and I wanted to step outside that thread for a moment to clarify terminology. I've been using "Chain Skip" to define my problem and I'm wondering if "Chain Slip" is the more accurate term.

From my continued reading and researching, I've started to get the idea that Chain Skip applies more to the chain skipping unexpectedly between gears (up or down) under various loads without using the shifter. It's not at all obvious my problem has this kind of symptom.

My issue appears to be (having trouble verifying it exactly) that with the chain in 1 gear only (in my case, 7th), it seems to be "skipping" teeth, not necessarily gears. Would this be better described as "Chain Slip" since the chain is actually slipping over/on (as in not "grabbing") the gear?

Thanks for help in clarification. It may explain why I'm getting some responses that seem to be a bit off from what I would expect.

Cheers...Steph

V belts slip, example: the squeaking of inadequately tight belts ,
like you hear on power steering pumps doing, in your car when turning the wheels, paralel parking.

toothed chainrings. and roller chains skip as the roller is pulled
off an excessively worn match of tooth and roller spacing..

the current trend to make click shifting work so early,
makes the situation worse, sooner
as the teeth have been shortened and shaped to make the shifting,
derailing, on & off the cogs easier..

Thanks for the clarification. It would seem I've been using the right term (maybe sometimes not clear enough in my explanations).

What you describe below is exactly my issue. It showed up suddenly when I replaced the chain/cassette and I haven't been able to get rid of it (even when I put the old parts back on to figure out which of the new ones might have been faulty). Check out my thread(s) and you'll get an idea what I've been going thru.

Again, appreciate the help.

Cheers...Steph
