This is probably going to have a very a basic answer, but thought that I would ask anyway as i can't find it anywhere on the net.

Is there anyway of converting a 68mm BB that came as OEM to be able to fit a new frame with a 73mm BB length?
Or will i have to buy a completely knew BB?

Can you buy internal spacers anywhere or the like?

For reference i'm using a RaceFace evolve XC Isis.

Thanks for your help.

    yes, just do not use 2 of the spacers.

    Thanks,

    Is there anywhere you can get the spacers? Or will a bike shop stock them in plenty?


    Thanks

    Sorry you miss understood me. the bb should be fitted with 3 spacers on a 68mm bb shell and 1 on a 73mm bb. so you need to take off 2. If your bb does not have spacers then new bb.
