In 11-30T F50-34T it is very comfortable feeling to change speed more than RD (RD - 2400 SS) of Claris. I just do not think that it will fit the sprocket of the cross ratio.
By the way it seems that the wire mounting bolt has been changed to a hexagon socket.
Although it is cheap if it is via Shimano, it takes time very much because it has little inventory, and your company that is in stock at the time of emergency response is saved. Too difficult, packing is too much. Since this product was originally packed items in the display box, it should also be included in a smaller box, is not it more costly that way?
