Installing my 1" carbon forks and the steerer seemed a very very tight fit when fitting stem and spacers before cutting. I didn't think much of it, come time to cut and fit, I cannot get the little plastic compression ring on the headset to sit in. I've been trying to sand the ring to see if it'll help push it down any further with no joy.
Well confused, the only conclusion I can make is the steerer is slightly wider than 1"?
It's an easton 1" ec90 aero with a campag record threadless.
