9 or 10 speed?

   Granted, this is just a listing on a bargain site, but seems like this is either the wrong cassette or it's missing a ring!
Chainlove at it's best.

   Still, this is a really cool cassette. The top 8 gears are made from one piece. Here is a look at how the manufacturing process works:

Steps 1 - 4

   You can see that they start from a block of aluminum. This makes them (apparently) lighter and stronger than  a conventional cassette. Conventional construction is to have 7 or 8 individual cogs all pinned together with steel pins. Here's another helpful cut away:

With backplate

The backplate is the top gear and I believe what is missing from the picture in the Chainlove image above. And at $150, even if it's missing a whole gear - what a steal!
