    Swapped this derailleur from a road bike to replace with an Ultegra derailleur. Works fine, needs some cleaning.

    Here is the link to the full specifications: 

    SHIMANO GRX DI2 Rear Derailleur 11-speed

    Asking $75. Original equipment installed on a 2019 bike. 

    Phone (707) 291-4401 and leave a message.

    Is this the 1x or 2x version of the derailleur?

    It is compatible with either a single or double chainring on the front crankset. The bike fit would depend on the alignment of the cassette with respect to the chainring(s). The maximum cassette range is 11-42. I've edited my post to include a link to the Shimano product page.
