• Remind me, did we work out if 2x GRX RD would work with a 46T or not?

    Further to that, will a GRX shift better on my current 42T than my Ultegra Di2 RD? ie. does it behave like the MTB RDs with the bigger cassette profile thingiebobs?

  • Mine shifts slightly worse than my R7000 when pushed above "Shimano stated working range", but might be the 1x chainline as well. The clutch is good.
