Can 11-40T 12s cassette work with Shimano Ultegra Di2?

TL;DR - it works, with minor issue. (Update: after some research and experiments, I believe the cog 12 to cog 11 shifting issue is related to B-screw being pushed further, hence when the front is on big, there are fewer links of the chain that can grab onto cog 11. I have just got a used GRX 825 rear derailleur and will seee if GRX 825 performs better in cog 12 to cog 11 shifting) (Update 2: I have tried GRX 825 and it worked really well!    • 558% gear range with Shimano 12 speed Di2   That's so far the best road/GRX build for climb with Shimano Di2) Previously I have tried and verified that 11-40T cassette works with Shimano 11 speed and 12 speed mechanic rear derailleurs. This time, I want to see if it also works with 12 speed Di2. Components: Crankset: Shimano GRX FC-RX610-2 Crankset (2 x 12 Speed) 46/30T Front derailleur: Shimano GRX Di2 FD-RX825 2x12-speed Rear derailleur: Shimano Ultegra Di2 RD-R8150 12-speed Cassette: GOLDIX 12 Speed 11T-40T (Shimano doesn't make 12-speed 11-40T cassette) ------------- Btw, the list of all the Shimano builds I have tried with 11-40T cassette: 12-speed 11-40T cassette and Di2 GRX RD:    • 558% gear range with Shimano 12 speed Di2   It works well. 12-speed 11-40T cassette and Di2 Ultegra RD:    • Can 11-40T 12s cassette work with Shimano ...   It works with minor issue. 12-speed 11-40T cassette and mechanic 105 RD:    • Can Shimano 105 RD-R7100 rear derailleur s...   It works well. 11-speed 11-40T cassette and mechanic GRX RD:    • Can Shimano GRX RD-RX810 rear derailleur s...   It works well. #bicycle #cycling #shimano #shimanoultegra #bicyclecomponent #rearderailleur #grx #di2 #ztto #goldix #bikelife
