• I've got an older Power2max unit (the pizza slice one) on a set of Rotor 3d cranks.
    I've just removed them from one of my bikes and noticed that the DTT bolt has unwound from its fitting on the NDS side.
    Velotech do a repair job which is £41 (plus postage) which is pretty annoyingly expensive - now considering replacing both crank arms instead as it wouldn't cost that much more and they are pretty beaten up.
    Has anyone done this? I've been trying to find a compatibility chart for Rotor cranks and the P2M spider as they have released a few new models recently.
    If I just buy some new crank arms for a 24mm spindle they should fit, right?

  • I've swapped Rotor 3df and 3d+ cranks with P2M S-version?. But I don't know your model.

    DTT? I need more coffee

    EDIT: you say 24mm spindle so you have 3D24?

  • Yeah it's the 3D24.

    DTT is a fucking stupid thread system that seems to break a lot of the time. Infuriating.

    The drive side is totally fine, only the NDS is an issue.
