• I'm getting a very slight chain rub on the front mech when I'm the lowest gear.
    Low limit on front mech is out to the max.
    It's a GRX chainset and ultegra front mech, I guess I either just live with it or get a grx front mech.
    Actually, no, that wouldn't help as it would be further out and rub more. Maybe it's inevitable with 30T inner ring. On my frame, anyway.

  • Depends where it rubs and how much, but you can try rotating the FD slightly, or bending the inner plate slightly (if you're sure you're on the limits)

  • Yes, it's a tiny little rub. I might be able to rotate it as there's a bit more space at the high end. I've put up with worse, though.

    It's packed on the car for holidays now so it will have to wait!
