So you need to go custom or do it yourself. Its going to be expensive unless you use cardboard, aluminum foil, paper, or some other ghetto **** that wont help anything. The only legitimate reason for NEEDING one of these is for a bike used for playing polo. Aero gains would be unnoticeable, and unless its a real disc wheel there will be no stiffness gains.

Make your own or buy the real thing, that being a true disc ranging from 500-1000 dollars.
