    Center Lock rotors don't have bolts
    you need a lockring tool (FR-5)
    Honestly... ahh I give up

    Agreed...

    the 07 HR Sport came stock with Shimano M65 centerlock disc hubs. The centerlock system doesn't use torx bolts to affix the rotor to the hub, they use a lock ring as highdell noted. A Park Tool FR5 cassette lock ring tool, or identical tool, will work to remove the lock ring and your rotors. For replacement rotors you'll either have to go with a centerlock rotor, or use a 6 bolt to centerlock adapter if the rotors you want are 6 bolt.
