Thanks rowan, Hub first definately. then wheels and spokes and then fork. when i get the hub ill try to get it off ebay or is that a bad idea.

As for a bar im thinking of getting either drop bars or a butterfly bar. not aero as i dont really want to be bent foward to much while ridding as on this tour ill be ridding for a while. ive got the same problem with drops (i think) if so to lesser extent (i think again)
