• Cheapest place to find 42T compatible GRX Di2 these days?

  • basically the same

    I thought XT would be better

  • DA front mech, so I think this won't work.

    re: grx 42T mech - I'm not even sure on the new bike it's working yet. They say it's 1x only but I've used it 2x, just without a GRX front mech (Ultegra) so I wonder if they've disabled it's ability to do 2x if run with a GRX front... that would be pretty fucked.
