    XTR Shadow B-axle movement

    Hi guys,

    Having not yet used a Shadow, I am wondering about the movement I have in my B-axle hanger. The hanger moves very easily in the directions pointed out by the arrows below, especially when moved from a 3 o'clock position towards the bolt stop.

    Check out this video of the issue:

    I have replaced the standard hanger with a carbon version, which might have contributed to this. Now I wonder whether this will affect my shifting or not. I suppose that once the chain is fitted, it will keep the derailleur from flapping about, but since I haven't used the Shadow yet, I'm not entirely sure of how the hanger works.

    Yes, that is supposed to happen. SRAM and Shimano stuff both do that. Just run the chain through and adjust.

    The gap is there to allow adjustment for the b-tension screw. That allows the whole derailleur to move on the screw and adjust based on different bikes, cassettes, etc. Varying amounts of "play" is normal since the b-tensions are probably adjusted different.

    For the record, I have 2 XT shadows.

    Movement on that axle is normal. Install the chain and ride.
