    just got a M8000 crankset and a new BB.

    The new BB cups are smaller in dia then the usual ones and need an adapter.

    however there seems to be two numbers one is

    TL-FC24 and the other is TL-FC25

    can anybody enlighten me as to which is correct please?

    I’ve just fitted a new BB on my road bike, wasn’t expecting the smaller cups in the box. The adaptor that came with it is a TL-FC25

    I bought the cranks off here, and no adapter in the box 🙁

    cheers

    I’ll order a TL-FC25

    25

    24 is for the smaller diameter ones, like Dura Ace (maybe M9000 too?)
