Adjusting a quick release seatpost clamp
In a seatpost quick release system, the seatpost is clamped in place by the force of the quick
release cam pushing against one side of the clamp and pulling the tension adjusting nut,
by way of the skewer, against the other. The amount of clamping force is controlled by the
tension adjusting nut. Turning the tension adjusting nut clockwise while keeping the cam lever
from rotating increases clamping force; turning it counterclockwise while keeping the cam
lever from rotating reduces clamping force. Less than half a turn of the tension adjusting nut
can make the difference between safe clamping force and unsafe clamping force.
1. With the quick release clamp in the OPEN position, insert the seatpost, with saddle
attached, into the bicycle’s seat tube.
2. Swing the quick release lever into the CLOSED position.
3. Grab the saddle with both hands and attempt to rotate it (and thus rotate the seatpost in
the seat tube).
4. If you are able to force the seatpost out of alignment with the frame, the seatpost clamp
needs to be adjusted. Holding the quick release lever in the OPEN position with one
hand, tighten the tension adjusting nut with your other hand about 1/2 turn clockwise.
5. Attempt to swing the lever into the CLOSED position. If the lever cannot be pushed all
the way to the CLOSED position (figure b), return the lever to the OPEN position, then
turn the tension adjusting nut counterclockwise one-quarter turn and try tightening the
lever again. Repeat steps 3, 4 & 5 until proper quick release tension is achieved.
