I just ordered the FLX-FR-701 for a project build. In the tech specs online it calls for a BB92. My question is on the headset size. I could not find out what combo I need to order for the taper head tube. I see that it mimics the CS-496 frame that was built upon this site. So, I searched for the topic in the 496 builds, but it looks like that frame came with a headset from the factory and there was no mention of the sizes used.  Anyone that built a 496 know what headset size was used?  would it be best to measure when the frame gets here in a couple of weeks?  Thanks for any input
