Cannondale 2.8 Series Road Frame

[Ultegra105]

ALL:

I am in the process of upgrading my bike from 9 Speed to 11 Speed 105 Groupset
I want to use a power meter like 4iii. Does anyone if I will have enough clearance?

I haven't used a current crank on a 2.8 frame but I don't think that there would be any clearance issues.

Thank you.
