Just put new bearings onto my winter bike (whoever thought press fit bearings were a good idea for us mere mortals!!), reinstalled everything, all looks ok. But just want to check - the wavy washer on the NDS isn't fully compressed - should it be? I'll see if I can pop a picture up

    Is there any movement of the crank side to side ? If not then its OK.

    If there is, you need to add more plastic shims.

    On my FSA SLK BB30 crank i had to use the bearing cover, then 3 plastic shims,then the wavy washer.

    It shouldnt be fully compressed. As above, as long as there is no play you are good to go.

    Excellent. I'll check the crank for play but it seems fine. Thanks for the help!
