To adjust the saddle height, begin by moving the rubber grommet up the seatpost to expose the seatpost wedge bolt.  Loosen the seatpost wedge bolt using a 5mm hex.  Apply grease to the seatpost wedge ramp faces and bolt.  Apply carbon paste to the seatpost at the clamping area.  Adjust the saddle height as needed.  Ensure that the seatpost insertion is within the range shown below.  Damage to frame and seatpost may occur if the seatpost insertion exceeds the value listed.  Torque the seatpost wedge bolt to 6.2Nm (55 in-lbf) and slide the rubber seatpost grommet back onto the frame.
