Hi, I have a DMR Drone '07 model and have bent the bottom bracket.

No. 1, Does anyone what type of BB it is in my bike? It's the one that came with it.
No. 2, Do I need a special tool to remove it and fit a new one?
No. 3, What new BB does anyone recommend?

Thanks.

    No 2)

    You will need either a BB tool or a external Bottom bracket tool, 90% it will be a normal bb tho

    or he could just buy a new axle and knock the old one out and fit the new one.

    But untill we know if it is the original 3 piece or an after market something.... and if it the expected MTB size BB.

    DMR dont really give out that much info.

    Also are you sure you have bent the axle?

    I feel it will be either

    That will depend on what cranks and BB setup you have. is there a name on the cranks? how is the BB fixed to the shell? How is the crank arms fixed to the bottom bracket?

    What exactly is the problem?
