Thanks to all who responded to my post!
Update:
I am acquiring both the alloy freewheel and required installation tool from Blackstridaaustria, who very graciously went out of his way to obtain these parts.
Bietrume, I visited the French Strida site and the US was not offered as a shipping destination. Didn’t email them given the other options I had locally. But thanks for providing another resource I can reference for all things Strida.
Areaware responded and stated that they are no longer the US distributor for Strida parts. As of this date, the current US distributor for such parts is East Coast Cycle Supply (ECCS).
