    Without the chain on how free should the crank turn? When you give it a whirl about how far Or rev's should it make? Mine will not go one rev? It is a FSH crank assy. I am thinking that is not correct??
  2. It should spin easily, at least two or three complete revolutions. Here's a short (45 sec.) video from another forum post:

    Which bike do you have it installed on?

    You have them too tight. Try backing them off until there is a little play in the crank, then slowly tighten until the play is gone and try again.

    May have already crushed the bearings

    If they grind when you spin them, yep.... Too tight.

    When setup right, it will spin many, many revs. Ratz stuck a video someone on a thread of his spinning and spinning. He was showing how great the XD-15 BB was.
    When I had my first Crizbike (Silvio) I had the rings too tight around the outside of the BB and it bound them up too. Just back off the tightness 1/4 turn and see if that helps.

    Well checked out crank, It seems to spin as free as the one in the video, Seems to me the change to XD-15 would be the way to go, should require less effort to pedal!!!!
