I used UPI as payment. It came in original cardboard box and product also seems similiar. If you have any questions, you can ask me on discord MeoW#3775
Awesome one of best Quality
got this derailleur for my MTB. i was looking for orignal product form Shimano and i got one from bumsonthesaddle. i would recommend bumonthesaddle for original genuine products. Thanks guys.
It doesn't make any noise during shifting and the fit was perfect from BOTS. Genuine product.
