I apologize if i'm posting this in the wrong place I'm new to this forum ... should probably be on here more to learn things.
Anyway!, was on a casual city bike ride last night and heard my front wheel spoke reflector fall off, .. the lil plastic fastener that holds it on just broke randomly... has this happened to anyone else?

Do bike shops sell that part so i can put the reflector back on? or am i screwed into buying a new reflector?
