Testing Seat Clamp And Post Clamp Tightness - Dynacraft MOUNTAIN BIKE Owner's Manual

If your bike has a quick release lever (see Figure 9), tighten it by holding the
lever in the "open" position and tightening the nut on the opposite side by
hand. Slowly close the quick release lever, and you should notice resistance
when the lever is half way shut. Firmly continue to push the lever until it is in
the "closed" position, and the word "close" is showing. The seat should not
be able to move back and forth, up and down, or side to side with the quick
release lever in the closed position. Make sure the lever is also parallel with the
seat clamp itself. You should only need one hand to close the quick release
lever. If you need two hands, the seat clamp is too tight. Loosen the nut on the
clamp until only one hand is needed to close the seat clamp.
If your bike has a standard seat clamp (see Figure 10), use (B) an Adjustable
Wrench(es) to tighten the nut securely. If your bike has a bolt on seat clamp
(see Figure 11), use (C) a 4, 5, or 6 mm Allen Wrench to tighten the bolt
securely. The seat should not be able to move back and forth, up and down, or
side to side with the seat clamp tightened.
3. TESTING SEAT CLAMP AND POST CLAMP
TIGHTNESS
After installing the seatpost into the bicycle and tightening the clamp, test the
tightness of the saddle. Hold the saddle firmly with both hands and try to move
it side to side. The seatpost should not move at all. The seatpost and saddle
also should not move when the rider is seated. Make sure the seat clamp nuts
at the top of the seatpost are tight so that the seat does not tip forward or
backwards (see Figures 12 & 13).
