Up to which translation

Martin - 21/11/2023

Hello! The text states that this item is with a short cage. Can I cover my gear ratio up to 34 teeth at the rear? With the 6870 with a short cage this only works up to 28 teeth. Thanks!

Answer of Armando Barbosa

Yes, it is for ratios above 28 teeth, excellent derailleur, the text says (type: GS) the GS is a medium long case if you want to change your 6870 derailleur from a short case, to a medium long case you can change it with this derailleur.

Compatibility shimano DI derailleurs

Bart - 28/10/2023

Is the GRX RX815 DI2 rear derailleur compatible with 6870 di2 system?

Answer of Baudouin

Yes, the GRX RD-815 Di2 derailleur is compatible with the 6870 Di2 but respecting the information on the Shimano website below. Note: To ensure correct operation of the Di2 electronic drive system, the different components must have the same firmware version. Reading or updating the firmware is possible using the optional diagnostic device. Using components with different firmware versions may result in malfunctions or operational failure. Greetings Baudouin

short cap?

Eric - 18/10/2023

Hello, is this really a short cover?

Answer of Baudouin

Hello, The derailleur is equipped with a long cage suitable for 11-34 T cassette. Greetings

is this GS or SS?

Michael - 09/10/2023

Is this the GS or SS cage version? the selection says max 34T which would be GS, but the description mentions a max of 30T which would be SS.

Answer of Baudouin

Hello, The derailleur is equipped with a GS cage for 34 teeth, I use it with 50-32 teeth and the tension of the derailleur still has reserve, so no problem for a 34T cassette. Very good product, driven +- 3,000kms since assembly. Greetings

Antonio V C - 14/07/2022

Very good, this product is the original "ULTEGRA Di2 RD R-8050-GS de 11v" since I see it has "ULEGRA" and "Shadow". They have it for immediate shipment. Thanks.

Answer of JOSE ANTONIO

Yes, shadow is the system, Ultegra is the model, Gs is the case type.

Answer of Bill

I use a lot of Shimano parts and prefer Ultegra to Dura Ave. I just put the Ultegra Shadow Di2 on a climbing bike and works perfectly.
