It is unlikely to fix it once it thaws it will most likely go back to being bent. i'd just hunt for a new one |

I found the two bits of wood and a club hammer didn't work for me. |

No need for a freezer, just leave it outside. Your lbs should have a rotor truing tool |

Or use a small adjustable spanner, rotate to bent section and carefully try and bend back. |

Find the warp then warm the whole rotor slightly with a heat lamp/ blow torch and clamp ithe warped bit in a vice, then leave it overnight so it cools very slowly, metal does a 'memory' but its pretty limited, alloy is even worse. Remember putting skyway Tuffs and ACS Z-rims in the freezer, all it did was make the alloy hubs or spokes brittle, never straightened anything ! |

Watch this. if you don't have a truing tool, as i said before a small adjustable spanner works. http://www.youtube.com/watch?v=nHdQkm14JVw |

Ive had ok luck clamping them in a vice and bending with a spanner. They are never quite the same. A new one is only £13 so might not be worth spending too much time on. http://superstar.tibolts.co.uk/product_ ... cts_id=197 |

I'd get a 203 and then pop a spacer under the brake if needed but you will prob find it goes straight on |
