Ah, thanks for that. That bolt/nut must be very narrow (diameter) because that wrench would not even fit on the spoke. Its opening is very, very narrow.
But I hope you don't mind my asking another question before I hit up the bike shop - can the handlebar be raised on this type of complex connection? After three days of riding I'm thinking I would not mind the handlebar a somewhat higher. I saw where he had different plastic collars. (I begin searching web)
