• Hi and thanks S.Suffolk, I've managed to borrow a mirage BB 115mm from my friends other frame to use as a reference and will fit the crank today and this looks closer than expected, will definitely find out once I tighen up the cranks, will be great if this works as the rest of the groupset is mirage...
    I have looked at the Tifosi BB's before but never used one have you used these before and would you recommend cheers.

  • 115mm is for triple cranks and the chainline will be 2mm out: whether that works or not you will soon find out...

    Yes I've used Tifosi and they're perfectly fine.

    Once fitted the BB won't be visible, so having it match the group is neither here nor there: I'd rather the correct length, than the "correct" name.
