    1 review for Shimano XTR RD-M9100-SGS rear derailleur Top normal 11/12-speed SGS long with an rating of 4/5 point.

    • Great buy as part of the group set. Shifter cable port could have been better designed
      Looks really nice and shifts flawlessly. Have put about 60km into it so far and there has been no chainslap at all. Would have given it 5 stars except the design of the shifting cable port makes the cable bend quite a bit. The polymer coating on my shifter cable is coming off a little, but this doesn't seem to affect shifting performance. Will see how it lasts.
