the steerer should fit about 3mm below the top of the stem, or in your Syncros stem's case 3mm below the red measurement, you may need to add or remove a spacer to get the right height and tension once the top bolt is fitted.In the below photo, can someone please tell me in mm how long the stem is for the red and green measurement. I'm trying to work out if I have enough steerer tube to use one of the syncros stems. Thanks Mike
