google it there are plenty of guides on how to fix such a problem, personally though i would buy a new wheel (a really fucking expensive carbon coated one) and send them the bill, if you fucked there car up they would make you pay so hows it ok to fuck up your bike and leave you with the problem of fixing it
I mean I can't send anyone the bill because they did it during the night. I had unwittingly left my bike chained up by the tennis courts which is by frat row. It's fucking frustrating. Oh well...
