Start by identifying your lever: generation 1 or generation 2.

Gen 1 lever is pictured on the left. Gen 2 lever is pictured on the right.

If you have a generation 1 lever use steps 2-7.

If you have a generation 2 lever use steps 8-12.

At this point you should already have your seatpost installed in your frame and the housing length sorted. Haven't done that yet? See here

Open the rubber access plug on the top of the lever revealing the T25 Torx cable fixing screw

Loosen the screw by turning it counter clockwise

Slide the cable into the lever

Be sure the cable passes through the hole in the small aluminum block

Pull cable through until it is tight

Slide the cable into the clamp

While pulling the cable tight, snug the clamp screw using a T25 Torx

If using new housing it is recommend to actuate the lever a few times to seat the housing ferrules onto the housing. After doing so, adjust the cable tension again.

Check the function of the lever and post, adjust cable tension as needed using the barrel adjuster

Tighten cable fixing screw to 3N*m

Using cable cutters, trim the cable

You can trim it close to the clamp or bend it down slightly and install a cable end close to the clamp (we removed the lever for a better view)

With the lever installed on the bike, adjust the paddle position to your preference and tighten the screw to 1N*m

You can also move the lever between the two mounting positions

Do a final check on the post function, seatpost clamp torque and lever clamp torque

At this point you should already have your seatpost installed in your frame and the housing length sorted. Haven't done that yet? See here

Loosen the 2mm cover screw and remove the cover screw and cover

Slide the cable into the lever

While pulling the cable tight, snug the T25 Torx until it bottoms in the hole. DO NOT EXCEED 1Nm

The unique cable-clamp design does not benefit from over-tightening.. so don't do it!

If using new housing it is recommend to actuate the lever a few times to seat the housing ferrules onto the housing. After doing so, adjust the cable tension again.

Check the function of the lever and post, adjust cable tension as needed using the barrel adjuster

Make sure you have about 15mm of cable exposed from the T25 cable fixing bolt

Using cable cutters, trim the cable.

Install the cable crimp and bend the cable slightly so it is tucked into the cable groove

Re-install the lever cover and tighten cover fixing screw to 1Nm

Install the paddle lever and install the fixing bolt

With the lever installed on the bike, adjust the paddle position to your preference and tighten the screw to 1N*m

You can also move the lever between the two mounting positions

Do a final check on the post function, seatpost clamp torque and lever clamp torque
