Of course the individual cogs are in pieces. That's because the freehub that the cogs will be mounted on is part of your rear wheel. Shimano Ultegra cassettes have the three lowest gears riveted together on a lightweight carrier and Dura Ace may have the 6 lowest gears riveted together on two carriers, which is one of the reasons that when I cobble together my 'custom' 10-speed cassette (11,12,13,14,15,17,19,21,23,25), I went with Ultegra so that I could remove a middle cog and replace it with the 11T. By the way, Shimano 11T cogs and 12T cogs use different locking rings, so use the one appropriate for your combo.
