    2013 New Shimano rear gear hanger standard

    See on Bikelive.com

    In addition to the redesign of the SLX group and of the Saint, and the possible arrival of a MTB Electric group, Shimano will make sense especially with the emergence of a new standard for fixing the rear derailleur. Unlike the solution proposed by Trek which offers a direct attachment of the derailleur on the central axis of the road, Shimano chooses to change the derailleur hanger of the frame with an offset on the very back. Besides easy of installation of the rear wheel welcomed by manufacturers, this solution will mainly allow Shimano to change its derailleurs Shadow and Shadow + who wanted to move from the small part that connects the body of the derailleur to the hanger a framework. Now, the setting will be more direct and therefore more rigid. In theory, this new configuration framework should not prevent the assembly of conventional derailleur.

    I'm trying to understand this and can't grasp what is going on. Is the derailleur hanger now part of the frame.

    Actually I don't know but I think not because It's really important to save the frame if you're falling down. The only thing I know is the hanger will be more on the back of the frame.

    Trek is working on a rear derailleur direct mount on the hub (as first Shimano saint) but it's a secret

    It looks to me like it gets rid of the short black piece that currently mounts to the hanger (see the attached photo) and now makes that part of the hanger itself. This could have some advantages:
    - Easier to remove/install the rear wheel.
    - Possibly lighter weight
    - More direct connection (fewer parts, fewer fasteners)

    Sooo, instead of it being directly below the axle, its way behind it?

    Looks like it. The "black part" with the hanger bolt is still there but just re-configured to allow for the new mounting angle.
    Interesting...
    Better to have and not need it, than to need it and not have it.

    This means that frame manufacturer's will have to change their design to accommodate this style of mount. Wow, everybody's talking to each other.

    Sure they do, becausevnow the frame makers and bike makers can sell you a new frame, because if you want the new best, bla, bla, bla group (electronic maybe), you need a new frame/ bike....
    Oh well....

    So, how will you mount SRAM to this? Unless they go with the new design too, I don't see this catching on.

    Who doesn't use a removable hanger now days. Looks like a simple $15 retrofit
