Hi
Is there any difference between BB91 & BB90? I wanna fit an XTR M985 double chainset to my S Works HT. I already have a M970 but wanna go double. My BB on the SWorks is BB91 but the XTR say they are BB90??
Thnks

    just a shimano press fit BB.

    see psarktools for the "low" down.

    most likely some typo somewhere.
