To Install The Seatpost
1. Grease the threads of the seatpost clamp bolts (Figure 4.2).
2. Insert the seatpost and tighten the seatpost clamp bolts to 5.2 Nm.
The seatpost can be inserted dry, or for more grip insert it with carbon prep on the
portion of the post that is inside the frame.
To Adjust The Height Of The Saddle
1. Loosen the seatpost clamp bolts (Figure 4.3).
2. Slide the post up or down as necessary.
Make sure the minimum insertion mark is inside the frame.
3. Tighten the bolts to 5.2 Nm.
To Adjust The Angle (Tilt) Of The Saddle
1. Loosen the saddle clamp bolt (Figure 4.3).
2. With your fingers, rotate the tilt wheel.
The tilt wheel acts like a nut instead of a bolt, so it will seem like it is left-hand threaded.
Note: When you tighten the saddle clamp bolt, the saddle angle will change about 3°. To
compensate for this change, turn the tilt wheel one full turn (the direction you turn the
wheel depends on the orientation of the seatpost in the frame) to lower the saddle on the
end at the tilt wheel. When you tighten the bolt, the saddle will flatten out and those 3°
will be erased.
3. Tighten the saddle clamp bolt to 5-7 Nm.
Note: If the tilt is wrong, repeat steps 1 through 3. Do not under- or overtighten the saddle
clamp bolt to achieve the correct tilt.
