• seat-tube is square. do think the few people i've seen with gravel bikes and mtb di2 2x i've seen have all had band-on clamps which obviously work fine. i was just hoping there was some direct mount adapter type thing someone had made. doesn't seem to be though.

  • The number of people using 2x MTB groupsets will be fairly small these days and the number of people wanting to put it on a gravel bike, even fewer.
    Just run 1x?
