I just bought a Schwinn Prelude project from a friend. He got it from the original owner, who apparently took the rear Maillard hub apart and lost the left cone, nuts, and a seal. The wheel looks okay otherwise. What success would I have trying to find a used Maillard hub and use the components in this one? Are there lots of different cones in Maillard hubs, or are they likely to be compatible in most?
