I tweaked your model a little using an approach you may want to try:
I modded the spoke with a flat spot near the hub end. It's labeled "location feature" in the design tree.
I modded the pulley with a cylindrical feature on the inner edge of the front face - "location features 1a & 1b".
The flat spot and cylindrical face were connected with a tangent mate.
Done!
No matter how many spokes are made or what angle they are at, the first spoke will always center itself and slide against the location feature 1b "pin". The sketch for "location feature 1a" has an angle dimension that can be adjusted so that the spokes line up with the hooks properly (I forgot to adjust it before I uploaded the file... oops)
If you put a very tiny part-of-a-circle "belt" cut on the inside curved part of the J hook, those can be made to snuggle up to the spokes properly, too.
I do stuff like this all the time in Solidworks at work. Normally after getting things mated up I would make the location features very, very tiny so they wouldn't be visible in any drawing - it also reduces any dimensional discrepancies to harmless levels. I left them pretty big here to be easy to find.
