I had a wheel with a Regina freewheel and I had a heck of a time removing it I went to a couple of bike shops who after looking at it said they could not remove it but one was able to sell me the Bicycle Research 2 pronged remover that fit the free wheel. After on various times trying to remove the freewheel I decided to stand on the wrench to try to free it and it worked. I then tried to take the cogs off the freewheel 1 and 2 came off fine but I could not get number 3 off in my attempt one of the whips broke the 24 tooth cog where it was drilled and so now my 5 speed Regina freewheel is toast.
