    Lockring vs. 6-bolt

    What are the differences? I have a lockring type on my bike. What is lighter, etc.

    Centerlock is a different rotor mounting interface. Basically Shimano designed it and only their rotors use it. I have several Centerlock hubs but use 6-bolt adaptors and standard IS 6-bolt rotors. Works fine. Kind of nice to need to tighten just one thing to mount rotors.

    The trouble with common sense is it is no longer common

    Shimano centerlock (lock ring style) are so much easier to take on and off... Not that I do that often though.
    When under pressure, your level of performance will sink to your level of preparation.

    Shimano centerlock hubs tend to be lighter than similar 6 bolt hubs

    Though the rotors tend to be heavier.

    If you use the 6-bolt adaptors it is basically a wash.

    shimano would like you to think their setup is lighter, stronger, and easier to remove due to spider. it may be lighter on XTR rotors with the big spider, on models w/ smaller spiders such as XT, it makes a weaker case. i see it just as a compatibility issue introduced by shimano b/c they think life was too simple
