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 compres-  
sion wedges.  
3. Adjust the tilt and setback of the saddle to your preference.

4. Follow the Inspection procedures to tighten the 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.  
3. Make sure the minimum insertion mark (Figure 4) 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

mark on seatpost  
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.  
Bontrager Warranty
