TAG Metals T1 Dropper Seatpost Installation

1.  Install the remote lever onto the clamp and tighten it to 4 Nm. (Fig. 1) Make sure to keep clearance between the remote lever and any brake or shifter controls.

Tighten the clamp bolt to 2 Nm. Less torque may be needed for carbon bars.
Refer to the handlebar manufacturer’s instructions for use with carbon bars.

2.  Route the cable housing from the lever into the internal routing port of the frame. Push the housing through the frame until the housing emerges from the seat tube and extends approximately 2 in (50 mm) beyond the seat collar. Install a ferrule on the seatpost end of the cable housing.

3.  Install the cable bushing onto the cable (Fig. 2). Seat the cable head into the counterbore of the cable bushing. (Fig. 3) Install the cable into the cable

housing starting from the seatpost end.

4.  Seat the cable bushing into the actuation cradle at the bottom of the seatpost. Pull the cable at the lever end while pushing the cable housing into the frame to seat the housing against the cable stop at the base of the seatpost.

5.  Insert the seatpost into the seat tube while pulling the cable from the internal routing port of the frame. Tighten the seat collar binder bolt to set the
seatpost to the desired height. 

6.  Determine how much cable housing is needed between the lever and the internal routing port of the frame. Make sure to allow enough slack for proper steering clearance. Mark the housing where you intend to cut, but do not cut it yet. 

7.  Remove the seatpost and cable from the seat tube, leaving approximately
2 in (50 mm) of housing beyond the seat collar. Remove the cable bushing from the actuation cradle. Remove the cable from the cable housing.

8.  Cut the cable housing at the mark. Install a ferrule onto the cable housing at the lever end. Lightly lubricate the cable and install it into the cable housing starting from the seatpost end. 

9.  Seat the cable bushing into the actuation cradle (Fig. 4) at the bottom of the seatpost. (Fig. 5) Pull the cable at the lever end while pushing the cable housing into the frame to seat the housing against the cable stop at the base of the seatpost.

10.  Insert the seatpost into the seat tube while pulling the cable from the internal routing port of the frame (use friction paste for carbon frames if needed).
Set the seatpost at the desired height.
NOTE: Excessive bolt tightness can adversely affect the action of the seatpost.

11.  Install the cable into the barrel adjuster of the lever. Ensure the barrel adjuster is turned completely clockwise. Pull the cable tight to seat each end of the housing. Hold the lever in the fully extended position (see image 1) while tightening the pinch bolt to 1.2 Nm.

12.  Press the lever down completely 5-10 times. To remove any cable slack, loosen the pinch bolt and pull the cable, then hold the lever in the fully extended position while tightening the pinch bolt to 1.2 Nm. Use the barrel adjuster to fine-tune the cable tension.

13. Cut the cable to the correct length. Make sure to leave approximately 0.3 in (8 mm) visible at the remote end. Install the end crimp and tuck the end of the cable.
