advice needed please! Rotor 3d cranks for Specialized Tarmac sl4

Hi all,

I want to get these rotor 3d cranks

(http://www.chainreactioncycles.com/rotor-3d30-road-crankset/rp-prod13044...

for my specialized tarmac sl4 2014 frame, has anyone done this before? I asked chainreaction for their advice and they said I needed this: pf46 bb for my bike

Does this work, has anyone tried this combo before on a tarmac/venge/roubaix?

let me know guys thanks!
