1.) For easy and accurate tightening we suggest to remove seatpost/ saddle. Flip saddle and put on a clean table surface with towel so saddle will not get damaged. Make note positioning of clamps.
2.) See below image to confirm clamp and hex bolt are positioned correctly before tightening bolt (single clamp bolt).
3.) Before tightening, check to make sure clamp is aligned with seat rail markings (see above). Not on the curve section of the rail.
Note positioning of hex bolt (see below) before thoroughly tightening.
