Patrick Moore claims to be confused, which I believe. Patrick Moore claims to have bought a product that he understands to be a 10-speed spacer, and that object measures 2.04mm in thickness Patrick Moore notes that St Sheldon's site says that 10-speed inter-cog spacers are 2.35mm in thickness
Patrick Moore requests an explanation of the above apparent discrepancy I suspect Patrick Moore bought a different product than he thinks he bought. There is a common product that enables one to fit a 10sp cassette onto an 11sp road cassette driver. That product is a spacer, and that spacer is 2.0mm thick. Problem Solvers is one vendor that sells such a product, and it has nothing to do with inter-cog spacers. I use 2.35mm when calculating 10-speed stack ups and I use 2.18mm when calculating 11-speed stack ups. The Performance webstore has a <$25 price on the Shimano HG-500 10-speed 11-25 cassette. That would yield a bunch of spacers and a bunch of useful cogs. The HG-500 model has no spider stuff. It's all cogs and spacers, riveted together and the rivets are easy to scrub out.
