How does a star nut fit??? FSA calls it a "conix" unit. Is this the same as a star-nut? Also, according my FSA headset manual, the conix unit that came with the headset may not fit an alloy steer tube, how do I know it doesn't fit? At Pricepoint the X-Vert is listed with a steel steer tube, so I think the conix unit should fit. The conix unit is just a hair to wide, in fact, I think if I gave it a few taps with a hammer it would pop in. Is it ok to use a hammer?
