|Syncros Headset + Easton Fork = Trouble||jose_Tex_mex|

|I tried to put a 1" threadless Syncros S-03003 headset onto my Easton EC70 fork and the bottom cup would not fit over the lower portion of the fork's tube enough to contact the race.
Has anyone ever had this problem? The EC70 is not one of those odd ball sizes that appeared so what's up?

|Threadless dimensions for cups and crown race are standardized to my knowledge. Although there is probably always room for an exception.Use to be there there wre several different threadings and cup and crown race dimensions depending on origin for threaded 1". Besides,he is talking aftermarket stuff.|
|the race went on, it was the bottom cup that would not fit over.||jose_Tex_mex|

|the portion of the fork by the crown that is wider in order for the race to be secure. This raised area would not allow the bottom cup to contact the race.
So much for open systems.

|The dimension we are talking about here is the crown race seat diameter. That is, the diameter of the fork steerer tube where the lower race (the crown race - the top of the fork is called the crown) sits (is seated). I'm not up on this lately, but back in the day there were two crown race seat diameter standards: 27.0 for Japanese, 26.4 Euro. If you have a 27.0 crown race seat, you'll never get a 26.4 on there, and if you have a 26.4 with a 27.0 crown race, it will flop around like a fish in the bottom of a boat.|| |
