Switching wheels and saw this spacer between the 13t and 14t cogs of my 12s Ultegra cassette. Its thinner than the other spacers. Is it correct? The spacing between cogs with it installed does appear to be correct. This is my first 12 speed groupset and I've never previously seen a thin spacer anywhere except at the base of the freehub.

No. It goes behind the biggest one. Put it first then the rest of the cassette.
