Hi everyone.

I have been searching google bit can't seem to find what i need. I have a 2011 Felt DA with di2 (BB30) and have recently purchased a Campagnolo SRM. Looking to buy the BB30 cups for the cranks i am faced with two options!?

68X42 or 68X46

Does anyone know which one i need to use on the frame so that i can install the SRM?

Thanks.

Looks like you need the 68x42, as the spec sheet seems to say your BB is standard BB30 not press-fit:
