I have not been able to find out where to obtain additional 2 part hubs for the 8" skywheels. Skyway only provided the wheels (less bearings, hubs & sprockets). At one time in previous competitions, similar hubs were provided by Small Parts I believe.
If someone actually knows where to obtain (Name, Phone #, P/N, cost, etc.), please post here.
in past years you have been able to order those hubs from MMH but in the team update 1 it states that IFI will be handling all of the extra parts and will have them on their site this week…i would look there first
if you have machining capabilities i can email you the cad file for them, i have seen alot of teams make them out of alum and delron
