I thought the Sprites were modified Records which were Raleigh's lowest quality frame and that the derailleur on the Sprites did not work very well. That is why I thought about changing things. If everything works i probably will ride it as is for awhile, but would like to get an internal hub eventually.

My main concern is if the axles of a new wheel set will fit in the dropouts. I wonder if the bolt would be too thick. Does anyone have experience with this?
