• even road derailleur can just about cope with 11-40 on a 50/34

    In every of the 22 gears? Including big-big and small-small?

  • My RD7000-GS did, even the 5800 did when paired with the roadlink, but you never use those gears apart from 5s of brain failure before you realize how much you're crossing.

    The nice thing of the GRX RD is the clutch, not the gear range

  • Yup.

    Bear in mind this very much depend on the derailleur hangers as not all us created equal.

  • I’ve got 11-42 with an R8000 and 30-46 GRX, it’s fine in all but small small but really shouldn’t be in that gear. I ordered the wrong GRX mech (the 1x rather than the 2x) and can’t get the 2x till end of summer. I don’t tend to find myself in small - small very often!
