This is NOT an iso 1"headset! I've just ruined a set of forks filing down the steererto fit what I thought was just a tight crown race only to find that the threads on the top race and locknut do not match those on my 1 " steerer - tried on an old 1" fork just to check with same result. To say I'm fed up is an understatement I now need a new threaded fork and another headset. A refund on the now stripped headset would be small compensation
