  • What do I need to fit these SI cranks on my bb30 caad7?
    I’ve got the cranks, bearing shields, a few small shims and wavey washer.
    Getting super confused reading tech docs but I keep seeing a big fat spacer on the non drive side, 5 or 10mm or something. Where can I find these?

  • If you are using the 109mm axle then you need the BB30 sisl2 non drive and drive side spacer.

    If you have the old 104mm axle then you don’t need them.

  • Do I have to take both arms off the axle to measure or is it between the arms? Or will it say on it?
    If it came off a caad12 before with bb30a would that mean it’s the 109?
