you can also get some string, tie one end to one of the dropouts. loop the string round the headtube and then back down and tie it round the other drop out. make sure you pull it tight. then measure the gap betweem the string and the seat tube on either side. helps to give you a idea if the stays are out of whack. then cold set it back in line.
