    68mm or 73mm BB?

    The internet is supposed to know everything, but I can't seem to find this one :

    What BB width do Fishers run? 68 or 73mm?

    Thanks in advance!

    Depends on the frame. Most are 73mm.

    Thanks for your reply.

    I was looking into a MRP 1.X chainguide for a 2011 X Caliber 29er. Because the guide is bb mounted, I would need a 68mm bb right?

    Just to stir it and get clarification here, I thought they are BB95, but the spacer on my RF says BB91-41......

    I'm not sure about the 2011 aluminum hardtails...they might also be BB95.

    If that's the case, I don't think you'll have any luck using a BB mounted chain guide. I think you're stuck with the ST moutned versions.
