Thanks Hazel! i still did not get the rack yet. Actually, the bike was put together before it arrived at Target. so someone does that all day long, i Sure hope they know a little bit about it..My hubby is going to try to help me tonight with the Derailer. it is a good name, i think a Shimano? anyway he's good at that type of thing, he is a very usefull hubby, so i i think he can help me.
