i thought the first vectors all had 1" steerers but depending on the frame they were being put on had differing diameter lower headset bearing race locations (crown diameter) and were shimmed at the top?? Thats how mine came from the factory anyway.
does a 1 1/8 headset race fit on the for properly or is it all sloppy and definately a 1"?
This morning I took the lower crown race off the steerer and low and behold it looks like a 1&1/8" every thing is covered in grease and it was hiding a step in the dia, but the rest of the steerer is 1".
