• Given all this 1x chat can anyone confirm that a Sram 10-42 11spd cassette would work with the Shimano GRX 812 derailleur? From a bit of Google it seems like it does work fine but isn't endorsed by Shimano. Anyone on here used a similar set up?

  • Cheers, it was more checking to see if it would handle the 10T. Seems like it would give quite a nice boost to top end gearing.

    Also the XD drivers are significantly lighter and no freehub biting so intrigued by the option.
