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
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

tighten the saddle
clamp.
