ATTENTION

This is a high performance product. It will give you reliable service if it is installed properly and regularly maintained by an authorized KS Service Center. Please read through these instructions fully and follow them carefully before you install your new seatpost.

WARNING

KS Height Adjustable Seatposts must be regularly maintained by a qualified service technician. If you need assistance locating a qualified service technician, more information can be found at http://www.kssuspension.com. Service center locations can be found at www.kssuspension.com. Do not disassemble your seatpost. Disassembly could cause damage and severe personal injury as some of the contents are under pressure. Failure to follow these warnings and instructions will immediately void your warranty.

Before You Install the Seatpost

Please be sure your new KS seatpost is designed to fit in your frame. All LEV Integra models are designed to fit either 27.2mm, 30.9mm, 31.6mm or 34.9mm seat tube inner diameters in frames originally designed for internal cable routing. Improper fit may cause slippage, faulty performance, injury and may result in void of warranty.

KS Suspension DOES NOT recommend modification or alteration of your frame in any way. Doing so may void your frame or bicycle's warranty and may result in frame failure which could lead to injury or death.

Make sure your frame is clean and free of debris, grease and the inside of your seat tube is smooth and free of any object that may score the seatpost.

Apply grease to all seatpost bolt threads.

Apply a friction or anti-seize compound to the inside of the seat tube and inserted surface of the seatpost. Do not use grease.

LEV-Ci: This seatpost uses a carbon fiber composite mast. Always install in a clean dry frame and always use fiber prep or suitable compound.

Always use the torque wrench when tightening the seatpost binder bolt. DO NOT EXCEED 5 N-m.

Seatpost Installation

Seatpost Orientation

Since Integra models remote cable is internally routed and in-line with the seatpost, there is only one position for saddle orientation.

Diagram description: Illustrations of correct seatpost orientation for LEV-Ci, LEV Integra, LEV-Si, e30-i, Crux-i, and eTen-i models, relative to the front and rear of a bicycle.

Minimum Insertion Distance

All seat post models must be inserted into the bicycle's seat tube to cover the minimum insertion line indicated on the seat post.

Insufficient insertion of the seat post into the bicycle frame's seat tube could result in damage to the seat post and/or bicycle and may result in a loss of control of the bicycle which may lead to serious injury or death.

Determining Cable and Housing Length

Temporarily install the remote lever in the desired final location. The remote can be installed on either the right or left side of the handlebar.

NOTE: You will use this position to determine cable length but remove and reinstall the lever again in a later step.

Install the supplied elbow noodle with integrated barrel adjuster and insert cable housing into the barrel adjuster.

Diagram description: Shows temporary installation of the remote lever on the handlebar (left or right side) and connection of cable housing to an elbow noodle with a barrel adjuster.

Diagram description: Compares a hinged lever clamp (4-5 N-m torque) and a non-hinged lever clamp (1-3 N-m torque) for remote levers, noting ODI Lock-On compatibility for alloy remotes.

With the housing and noodle in place at the remote lever, route the housing through your bicycle frame per your bicycle frame manufacturers specifications.

To determine the correct length for your housing, pull the housing to remove excess slack with the handlebars turned 90-degree from the forward position. Be sure the housing is long enough to wrap around the head tube as shown to not impede with steering.

NOTE: Do not permanently affix your housing in place. You will need it free to move it in a later step.

Diagram description: Illustrates routing the cable housing through a bicycle frame, ensuring sufficient length to wrap around the head tube without impeding steering.

Mark the location on your cable housing at the seat collar as it protrudes from the seat tube. Pull the cable housing out of the seat tube and make another mark 110mm in the direction of the handlebar. This will be your final housing length. Cut the housing to length.

NOTE: This 110mm measurement applies to all travel options.

Cable Installation

Connecting the Inner Wire

With the housing still routed through your frame, install the ferrule on the end of housing at the seat collar.

Diagram description: Shows ferrule installation on cable housing at the seat collar.

Feed the inner wire through the remote lever, integrated barrel adjuster and cable housing.

Diagram description: Illustrates feeding the inner wire through the remote lever, integrated barrel adjuster, and cable housing, and pulling cable slack from the seat collar.

Option 1: Using a standard shifter cable

Hold the free end of the cable and cable housing to the cable entry point. Mark this length on the cable and cable housing with a marking pen or tape. Using a pair of bicycle cable cutters, trim the cable housing to this measured length. DO NOT cut the inner wire at this time.

Mark the inner wire to a length 18mm longer than the cable housing or use the gauge molded into the supplied protective cap as shown.

Diagram description: Shows the seatpost being placed into the seat collar while managing cable slack.

Saddle Installation

General Saddle Installation

Once you have oriented your seatpost within your seat tube ensuring the saddle is aligned to point forward, you will need to install your saddle. Remove the two saddle head clamp bolts, spherical nuts, upper and lower floating clamp using a 4mm Hex wrench.

Note: The lower clamp body may slide down the stanchion tube at this point.

To install the saddle, replace the two saddle head clamp bolts, spherical nuts, upper and lower floating clamp in the order in which they were removed.

Before tightening, place the rails of your saddle between the upper and lower floating clamps so that the rails seat in the channel provided by the lower floating clamp.

Using a 4mm Hex wrench, tighten the two head clamp bolts until the desired saddle angle is achieved. Then tighten both bolts evenly to a maximum torque of 10 N-m (8 N-m LEV-Ci).

Diagram description: Shows saddle clamp components (spherical nuts, floating clamps, head clamp bolts) and details removal/reinstallation. Specifies torque values (10 N-m, or 8 N-m for LEV-Ci).

CRUX-i Saddle Installation

Using a 5mm Hex wrench, loosen the two head clamp bolts until they are nearly free of the upper half of the saddle clamp. Set the fore/aft and angle position of the saddle. Tighten the two head clamp bolts to a maximum torque of 15 N-m.

Diagram description: Shows saddle clamp bolt tightening for CRUX-i (5mm wrench, 13-15 N-m torque).

ETEN-i Saddle Installation

Using a 6mm Hex wrench, loosen the single head clamp bolt until it is nearly free of the upper half of the saddle clamp. Set the fore/aft and angle position of the saddle. Tighten the head clamp bolt to a maximum torque of 22 N-m.

Diagram description: Shows saddle clamp bolt tightening for ETEN-i (6mm wrench, 20-22 N-m torque).

Adjusting the Return Speed

(LEV-Ci, LEV Integra and LEV-Si Only)

NOTE: All LEV Integra models come with suitable pressure for the return spring. Test the return speed of LEV Integra before you make adjustments. If air pressure adjustments still must be made, remove the saddle and saddle clamp parts at top end of the stanchion tube.

Attach a compatible shock pump and adjust to your desired pressure. KS recommends our AIR-8 High Pressure pump for best results.

NOTE: Recommended operating pressures is 100-250psi. Do not exceed 250psi.

Diagram description: Shows components for adjusting return speed and attaching a shock pump to set air pressure (100-250 psi recommended).

Using Your Seat Post

For the First Time

When using your seat post for the first time, it may be necessary to give the post a firm downward "nudge" to start the initial movement. This is due to the seal's natural tendency to migrate oil away from the seal surface. This is only necessary prior to the first use or after a long period of non-use. Once the post is cycled through its travel the first time, it will distribute oil on the seal and resume its normal function.

Raising and Lowering the Saddle

To lower the saddle, weight the saddle firmly with your hand or sit on the bike while pressing and holding the actuation lever or remote. Release the lever when the desired height is reached.

To raise the saddle, actuate your seat post by pulling the lever or handlebar remote. Unweight the saddle and release the lever when the desired height is reached.

You can raise and lower your saddle to any desired position within the seat post's travel.

Safety and Maintenance

Before Each Ride

Before each ride, check that the seat post is secure in the frame and that all clamping bolts are tightened to their specified torque values. Make sure that your seat post does not show sign of excessive wear and is not leaking. Check that the seat post functions properly. Make sure that the maximum raised position of the seat post is not too high for the rider to properly maintain control of the bicycle.

Periodic Maintenance

Your KS seat post requires periodic service to maintain consistent function. Please see your local dealer to have this service performed.

Routine maintenance should be done at regular intervals. Interval duration will depend on frequency of use and conditions. Post should be cleaned and lubricated at least once every 6 months. Wet or severely dusty conditions will require more frequent maintenance. If a high pressure water is used to wash the bicycle, more frequent maintenance is recommended due to the increased chance of water entering the system. If degradation of performance occurs, perform maintenance as soon as possible.
