    Can you do a Deore 10 speed hyperglide shifter, I have Linkglide 10s cassette with 10s hyperglide shifter and derailleur, and it works, I am guessing the pull ratio, cable pull and cog pitch are very close.

      M4100 shifter + M5120 RD + 11-43T 10s LG cassette + 11S chain works flawless!

      @@rafailloparev2070 For me, I needed I-Spec EV (not available in CUES) for my SLX brakes, I have SL-M4100 I-Spec EV (10s) Shifter + M5100 RD (11s) Derailleurs +11-48T 10s LG Cassette + 11s LG Chain, works perfectly.

    Excellent measurements!
    I've done an identical test on my deore 11 speed shifter and found an avarage cable pull of 3.45 to 3.5 mm for the 2 measurements series I did. I was using a very old 50mm travel dial gauge I had 'lying' around and it was a bit sticky so there are some errors in between the measurments.
    I have also done some measurements on the deraileur travel, but they were quite a bit more tricky. Although the derailleur I used was quite new, what I observed was that the movement of the derailleur depended in part on the chain line. In the highest and lowest gears the chain is not travelling in a straight line to the front chain ring (i used a 1 by setup) and this actually works a against the cable pull. So the larger pull at the both ends will to a certain extent counteract this restriction. (it was a new chain I used with very little sideways flex).
    The reason I did this was to design a cable pull adapter which would allow me to use a drop bar ultegra 11 speed shifter with the deore derailleur which would allow me to run a 11 to 46 MTB cassette. I had one of these a while ago but it didn't work reliably enough so I drop that idea at the time but I am now back at this project. In the meantime I am using a flat handle bar with the deore shifter, but would like to get back to the drop handle bars on account of the winds here in scotland.
    I have also done the cable pull for a 11 speed ultegra 6800 and found an avarage cable pull of 2.47 and 2.51 mm for the 2 measurements I did.
    Excllent work!

      Thank you!
      Regarding derailleurs, it's really tricky to measure them since the jockey wheel is moving all around in 3 dimensions.
      Good luck with your cable pull adapter project! I know J-Tek has produced a lot of them, but I also wonder if it's possible to 3D print one. If you want to go straight to indexed 11-speed Deore, you could try Microshift XLE drop-bar shifters.
      You're measurements for Ultegra 6800 line up with my measurements for ST-R8020. Good work!

      @@boothsbikeprojects I totaly agree with your commnt on derailleur measurements. They are tricky to perform reliably with gauges, but I was able to use a high precision 3D scanning system to do the task.
      The reason why I have to design my own "j-tek" typeadaptor is that my fram has internal cable routing and with the deore derailleur there is VERY , very limited space between the point where the shifter cable emerges from the chainstay and where it goes into the derailuer adjuster. Even for normal operation I hade to remove the adjuster barrel to get an acceoptable near 90 degree curve in the 45mm long jacket .
      PS I will have a look at the microshift XLE shifters
