• Torqued up to 40nm and checked regularly, you will probably be ok with a backwards BB though obviously not what you would have wanted.
    Assuming you're using Shimano as you said you needed di2 routing so it should be fine either way round.
    I don't know if the first batch were BSC (that everyone refers to as BSA) or T47 but it is the same situation either way.
