• They have the word ‘mountain’ etched on the cups so fairly sure!
    But confusingly the website lists them as road/XC.

    But you could in theory run them with a road crank on a 68mm shell. I think you could install them with no spacers. But the middle plastic axle sleeve might need to be swapped out for a shorter road variant.

    That’s a lot of a if’s and but’s though. Maybe someone who’s done this could chime in!?

  • And just for the record, the bb can be used on a 68mm shell with shimano road cranks.

    The length of the inner sleeve is usually what stops a Mtb bb being used with road cranks.
    But the sleeve and cups are designed in a way that lets the cups slide further down the sleeve when using a road crank set.

    I don’t know why I didn’t think to read the instructions before.
