YOu need a 7 speed chain for a 7 speed system. I t has to do with the width of the chain, not the length.
A 9 speed is more narrow casue the cassette cogs (gears) are more narrow (fitting more cogs into a samll area). 7 has thicker cogs cause there are few fitted into nearly the same area as the 9 speed cassette.
Length has to do with how the number of teeth on the biggest cog in the rear and the biggers ring up front.
Your narrow chain ( sspeed will not sit properly on the thick 7 speed cog on your cassette.
Plus, if a cassette is fairly worn, a new chain will skip. Most times the cassette has to be replaced if this skipping condition is present with a new chain..
Means the teeth on the cassette are worn and don't fit into the chainlinks properly.
