We had a few prototype Freecoaster hubs made. Designed with the Original Tree hub spoke pattern that uses J-bend spokes all inverted to protect the spokes from grind damage. Can be used with or without hub guards.
Mechanism is based on the standard internals that are in all the other off-the-shelf coaster hubs.
