    Hi, Just a quick question

    I have a raceface x type dh race BB on my santa cruz blur with a raceface respond crankset.

    I need to replace my BB and I’ve noticed that there are different sizings on the shell case. Does anyone know what sizing I would need for mine. I don’t have the tools to take it apart.

    All it has written on the BB other than what I’ve mentioned above is – 35ft – lbs 47nm.

    I’ve noted that the sizings for the shell casings are

    68mm/73mm
    83mm

    I guess I’m right in thinking that the 68/73mm is the correct sizing for my blur rather than the 83mm which is more for dh bikes?

    cheers.

    Just measure the width of the frame between the BB cups, my guess is 73mm.
