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?
PhilDAS-
Will be 109mm if it came off a CAAD12, yep.
This guy had the same issue and found where to buy the spacers from (ended up being US by the look of it)

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.
