euro scooters are shit..they dont stock any parts...theres a piggy dealer in kilburn that stocks parts....
cancell the order.. go to a pushbike shop.. buy a rear brake cable wire. drill the hole in the splitter slightly bigger (not needed but it will snep qwuicker) and its done.. its a slightly undersized one. might aswell get a new sleeve while your at it (wilkensons sell themw hole thing for 99p)
