If you have a question or problem that your Bontrager dealer can’t handle, contact us at: Bontrager Components (800) 369-8735 Attn: Customer Service 801 W. Madison Street Waterloo, Wisconsin 53594 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 seat, seatpost, and seatpost binder. 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 post binder (Figure 2): 85-125 lb•in (9.6-14.1 Nm). • Seat fixing bolt: 120-130 lb•in (13.6-14.7 Nm). For a seatpost binder using a quick-release lever, the mechanism Figur FigurFigure ee 2 22- --S SSe eeatpo atpoatpost parts works the same as a wheel quick-release. Adjust the lever tension, and make sure it is in the CLOSED position. Installation instructions 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 1. Loosen the seatpost binder bolt. 2. Twist the saddle to loosen and partially remove the seatpost from the frame. 3. Re-tighten the seatpost binder bolt. 4. Loosen the saddle clamp bolts enough to remove the saddle from the saddle clamp. 5. Remove the seatpost. 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. 6. Tighten the seat clamp bolt. To install the saddle 1. Loosen the saddle clamp bolt (Figure 4). 2. Slide the saddle rails into the rail grooves of the compression wedges. 3. Adjust the tilt and setback of the saddle to your preference.

Figure 4-Exploded view of saddle clamp 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. 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. Figur FigurFigure ee 5- 5-5-Minimum MinimumMinimum insertion 3.
