The hex hubs are machined from hex stock and the outside fins that hold each roller are bolted onto the outside of the hub. This way, if we somehow bend a fin during a match (the bumps liked to do that this year), we can swap them out between matches with spares and you don't lose an entire wheel.

The rollers were cast with certain materials this year from silicone molds. The rollers themselves have two layers, a hard inner core and a softer outer traction layer. I'll see if I can get some of the students who made the rollers this year to post more details.
