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

    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.
