    Hub and/or wheel flex?

    When i installed the rotor i did everything to spec. As the rotor was bedding in it was fine. Then after it heated up it started to drag a little bit so i re-aligned the caliper and pads and played with the QR pressure.

    After this the rotor was pulsating through the lever under braking. When i stopped and spun the wheel it was perfect. But when i got on the bike and pedalled the rotor would lightly rub the pads.

    This is on a 293 using the OE wheelset.

    '05 Avid brake/rotor? That 'might' explain the pulsing.

    If not, sounds like you need to have the disc tabs faced by your LBS.

    can the disc tabs work fine with a 160mm rotor but then be off for a 185mm rotor? So the wheel isnt impacting the rotor rub?

    Sounds like the rotor is warped. You can true it with a crescent wrench. Spin your wheel and watch were the rotor touches the pad. Mark that spot with a felt pen. Then take a crescent wrench and persuade the rotor in the correct position. I emphasize “persuade” do not “honk”.
