Installation

1. Install the remote lever (5) on the handlebar. Ensure the remote lever does not interfere with other controls. Use a 3 mm hex key to tighten the handlebar clamp to 1.6 N·m.

2. Cut 4mm shifter housing to a length appropriate for the frame size and frame manufacturer’s recommended routing. Housing should extend from the bottom of seat post to the handlebar lever barrel adjuster (6). Install ferrules

(7) at both ends of the housing.

3. Route the housing according to your frame manufacturer’s recommendation.

4. With the DownLow dropper post removed from the frame, install the cable head (9) in actuator (4). Ensure that the cable head is fully seated in the actuator as shown.

8. Tighten the DownLow dropper post using the clamping mechanism on the frame. Tighten to the manufacturer’s specified torque.

9. Lightly tension the cable and anchor the cable at the lever using a 1.5 mm hex key to tighten the set screw to 1.2 N·m.

10. Use the barrel adjuster (6) on the lever to take up any slack in the cable. Cut excess cable at the lever and use a cable end crimp to prevent fraying.

11. Install the saddle rails between the saddle clamp (1). Using a 5 mm hex key, tighten the clamps evenly around the rails of the saddle between 8-10

N·m. Be sure to also observe any torque specifications from your saddle manufacturer.

12. Test the DownLow dropper post for function. Sit on the saddle with the

DownLow dropper post fully extended. If the saddle drops with without pushing the lever, decrease cable tension by turning the barrel adjuster counter-clockwise. Push the lever. If the saddle does not drop, increase cable tension by turning barrel adjuster clockwise.

How to Use the Seat Post

A dropper post allows you to set variable saddle heights while you are riding.

Varying saddle heights are helpful when ascending (higher saddle) and descending

(lower saddle).

If you press and hold the handle bar lever with your weight off the saddle, the saddle will rise stopping when your weight stops the saddle. Release the lever and the upper tube with will hold the saddle in the position.

If you are seated on the saddle and press the lever, your weight will cause the saddle height to drop until you release the lever.
