Seatpost cam action clamp

4. Then, insert the wheel into the frame
dropouts and pull it all the way in to the
dropouts.
5. On a single speed or an internal gear
hub, replace the chain on the chainring;
pull the wheel back in the dropouts so that
it is straight in the frame and the chain has
about 1/4 inches of up-and-down play.
6. With a cam action system, move the
cam lever upwards and swing it into the
CLOSED position (fig. 4-1 & fig. 4-2 ). The
lever should now be parallel to the seat
stay or chain stay and curved toward the
wheel. To apply enough clamping force, you
should have to wrap your fingers around
the fork blade for leverage, and the lever
should leave a clear imprint in the palm of
your hand.
7. With a through-bolt or bolt-on system,
tighten the fasteners to the torque specifi-
cations in "Fastener Torque Specifications"
on page 70 or the hub manufacturer's
instructions.
NOTE: If, on a traditional cam action
system, the lever cannot be pushed all the
way to a position parallel to the seat stay
or chain stay, return the lever to the OPEN
position. Then turn the tension adjusting nut
counter-clockwise one-quarter turn and try
tightening the lever again.

Securely clamping the wheel with a cam
action retention device takes consid-
erable force. If you can fully close the
cam lever without wrapping your fin-
gers around the seat stay or chain stay
for leverage, the lever does not leave a
clear imprint in the palm of your hand,
and the serrations on the wheel fastener
do not emboss the surfaces of the drop-
outs, the tension is insufficient. Open
the lever; turn the tension adjusting nut
clockwise a quarter turn; then try again.
See also the first WARNING in this Sec-
tion on page 25.
8. If you disengaged the brake quick-re-
lease mechanism before removing the
wheel, as described above, re-engage it to
restore correct brake pad-to-rim clearance.
9. Spin the wheel to make sure that it
is centered in the frame and clears the
brake pads; then squeeze the brake lever
and make sure that the brakes are oper-
ating correctly.
Seatpost cam action
clamp
Some bikes are equipped with a cam
action seatpost binder. The seatpost cam
action binder works exactly like the tradi-
tional wheel cam action fastener ("Wheels
with cam action systems" on page 25).
While a cam action binder looks like a long
bolt with a lever on one end and a nut on
the other, the binder uses an over-center
cam action to firmly clamp the seatpost
(see fig. 4-1 ).
