Non threaded BB shell

Posted on
  • Can't get my head around this, sorry.

    I have a new carbon track bike which has a non threaded BB shell and I can't work out how my current BB fits there. Can I use a Sugino 75 in it or do I have to buy extra parts? Or do I have to use a different system altogether.

    Google-fu may be failing me but I can only find references to press fit and I can't understand how the Sugino 75 bb would work with this.

  • Photos and or link to frame spec will help.

    If it's a press fit BB like PF30 you need an adapter to run a cartridge BB for S75s.
