Apologies about the late response but I was considering sending the wheel to zipp but it is too much hassle and as I don't have a reciept, it's unlikely I'd get anything done.
A shop has no legal obligation to provide a receipt when purchasing - you also do not need a receipt to return faulty goods - don't let anyone tell you any different.
