    Anyone know what BB tool to use for removing a Sram DUB PressFit bottom bracket?

    This is for removing the Sram DUB Press Fit 92 bottom bracket from a Trek Fuel so that I can install a dropper post.

    Thanks.

    Did you ever find an answer to this? I can tell you what doesnít work:
    BBT 30 - too big
    BBT 90.3 - too small.

    I donít want to use a screw driver but that might be my only choice. Uhgg.

    If anyone has any recommendations please help.

    Thank you

    Figured it out.

    First, one could use a punch and a hammer. However, I donít like the downside risk of that so I prefer a specific tool.

    I called Wheels Manufacturing and they donít have a specific tool yet. SRAM does not appear to have one.

    So, I bent the prongs of the Park BBT 90.3 and it worked perfectly on the non drive side. Then used the BBT 30 on the drive side.

    Using the BBT 90 on the drive side could work but you would likely ruin the bearing. The plastic cylinder between the bearings allows for the appropriate purchase when removing the non drive side. But the cylinder comes out with the non drive bearing. So, for the drive side, if one were to use the bbt 90 with bent prongs you would end up hitting the seal, not the race. Using the bbt 30 allows you to contact the race.

    BBT-90 non drive side, a bit too small but it kind of works.
    RT-1 for drive side, came out easy. Not sure if this would have worked for non drive side or not.
