Shimano Alfine Hub rotor removal

I'm trying to replace a broken spoke on my wheel but before i can do that I need to remove the rotor (disk brake) from the hub gear. (SHimano Alfine Sg-S500). This is where i'm having trouble, i have no idea how to remove the rotor as there are no obvious screws to undo.

My hub looks similar to this: ... sc-hub.jpg

I can't find any videos online of how to do this. Only exploded drawings of the components which dont really describe how to take it apart.

Any help would be great..




  • Hi,
    I can't be certain but I think the disc is centre-lock and will be held on by a lockring at the hub. If so you'll need a cassette lockring removal tool to undo it.
    Hope that helps

    No need for a chain whip on center lock discs.
    I've added a signature to prove it is still possible.
