Also the 30-24 = 6, so both changes are the same.

I think one wraps about 1/2 the way around a chainring (maybe plus or minus 1 tooth depending on tangents).

So, the answer is probably closer to removing 3 single links, or between 1 and 2 double links.

However, that should just be a rough guide. Throw the chain on the big/big combo and the small/small combo, and see how it fits.

Also, check your chain for wear. No sense in mounting a heavily worn chain on new parts, potentially damaging one's chainrings and/or cassette.

If the derailleur cage is long enough, then as [MENTION=68015]DiabloScott[/MENTION] mentions, perhaps no change would be necessary.
