If you do not understand the information in this manual, or you have a question about your seatpost that this manual does not cover, consult your Bontrager dealer. If you have a question or problem that your Bontrager dealer can't handle, contact us at: Bontrager Components 920.478.4678 Attn: Customer Service http://www.bontrager.com 801 W. Madison Street Waterloo, Wisconsin 53594 © Copyright Trek Bicycle Corporation 2004 All rights reserved The seat, the part you sit on when riding a bike, is held in place by the seatpost (Figure 2). The seatpost binder secures the seatpost in the frame. Proper adjustment of each component is important for your comfort and pedaling efficiency. This section explains how to inspect, adjust, and lubricate your seatpost. Inspect your seatpost regularly Every month inspect the seatpost quick-release lever, or seat post binder bolt, and seat fixing bolt (Figure 2) for proper tightness. Make sure the seat is secure by attempting to turn the seat and seatpost in the frame, and attempt to move the front of the seat up and down. If the seat rotates, is loose, or moves up and down, tighten the binder bolt or quick-release, or seat fixing bolt, and repeat the test. Never engage the seatpost binder with the seatpost out of the frame. Tighten the following bolts: Seat fixing bolt Seatpost Seatpost binder bolt Figure 2- Seatpost parts · Seat post binder (Figure 2): 85-125 lb·in (9.6-14.1 Nm), or 65-80 lb·in (7.3-9 Nm) for a carbon fiber seatpost. · Seat fixing bolt: 100-150 lb·in (11.3-17.0 Nm). For a seatpost binder using a quick-release lever, the mechanism works the same as a wheel quick-release. Adjust the lever tension, and make sure it is in the CLOSED position. Inspecting a carbon fiber seatpost Unlike metal parts, carbon composite parts that have been damaged may not bend, bulge or deform; a damaged part may appear to be normal to a cursory glance. After any high force load, like a crash, or other impact to your bicycle, thoroughly inspect your carbon composite seatpost: · Check for scratches, gouges, or other surface problems. · Check the part for loss of rigidity. · Check the part for delamination. If the part has any problems, do not ride the bike. Take the bike to your dealer for replacement or further inspection. WARNING A damaged carbon fiber part can fail suddenly, causing serious injury or death. Inspect a carbon fiber part for damage frequently. If you suspect a carbon fiber part is damaged, replace the part before riding, or take the bike to your dealer for service. 2 Installation instructions Bontrager Race, Race Lite, Race X Lite, and Race XXX Lite seatposts are only compatible with saddles having mounting rails of 7mm diameter. If you are not sure of the diameter of our saddle rails, consult your dealer. Generally, it is easier to remove the saddle with the seatpost held firmly in the bike frame. However, the old seatpost may be corroded slightly, making removal or the seatpost difficult without the seat attached for leverage and grip. These instructions explain how to remove a seatpost that may be slightly corroded. To remove an old seatpost Loosen the seatpost binder bolt. Twist the saddle to loosen and partially remove the seatpost from the frame. Re-tighten the seatpost binder bolt. Loosen the saddle clamp bolts enough to remove the saddle from the saddle clamp. 5. Remove the seatpost. 1. 2. 3. 4. To install the seatpost 1. Visually inspect the top edge and interior surface of the seat tube for burrs or deformation that might mar the seatpost. 2. With your finger, again check the seat tube. If there are any rough spots or burrs, remove them before going to the next step. 3. Grease the seatpost, except for models with a carbon fiber seatpost tube. Apply a light bearing grease to the seatpost where it inserts into the seat tube. This helps prevent galvanic corrosion where the aluminum seatpost can chemically bond to the steel, aluminum, carbon, or titanium seat tube. Some manufacturers tell you not to grease the seatpost with some frames. As an example, Trek says that a special insert inside the seat tube of OCLV carbon frames means you should NOT grease a seatpost inserted into an OCLV frame. If you are unsure, check with the manufacturer. 5. Insert the seatpost into the frame to its minimum insertion mark. Saddle rail 6. Tighten the seat clamp bolt. locations To install the saddle Figure 3- Bontrager saddle rails clamping mechanism 1. Loosen the saddle clamp bolt (Figure 4). 2.

Saddle clamp bolt Figure 4- Exploded view of saddle clamp 3 To adjust the saddle tilt 1. Loosen the saddle clamp bolt several turns. 2. While tilting the saddle, apply pressure to the top of the saddle directly above the saddle clamp. Pressure on the saddle helps release the compression wedges. 3. Tilt the saddle to the desired angle. 4. Follow the Inspection procedures to re-tighten the saddle clamp bolt. This line must be hidden inside the bike frame Figure 5- Minimum insertion mark on seatpost To adjust the saddle height 1. Loosen the seatpost binder bolt, or quick-release. 2. Slide the seatpost up or down to your preferred saddle position. 3. Make sure the minimum insertion mark (Figure 5) on the seatpost is not visible above the bike frame. A minimum of 2 1/2 inches (64 mm) of seatpost must remain in the frame. 4. Re-tighten the seatpost quick-release, or bolt, as described in Inspection. WARNING A seatpost that is positioned too high can damage the bike and can cause you to lose control and fall. Make sure the minimum insertion mark (Figure 5) is inside the frame.
