Need to replace a bladed spoke on my Easton Ea90 aero rear. Mixed info on goggle about if they're cx or cx-ray. Anyone in the trade know tru-fact or should I just get in touch with Easton?

Let me lavish some facts on you: you can measure spokes, Sapim advertise the dimensions of their spokes, point 20 is about replacing a rear wheel spoke - http://www.eastoncycling.com/en-ca/road/faqs/.
