(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 s ystem, move the cam lever up wards and swing it into the CLOSED posit io
n (fig. 8 a & b). 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) W ith a thr ough-bolt or b olt-on s ystem, tighten t he fa steners to th e torque s pecifications
in Appendix D or t he 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 ad justing nut coun terclockwise one-q uarter turn and try
tightening the lever again.
WARNING: Securely clamping the wheel with a cam ac tion retention device takes considerable force. If you can
fully close the cam lever without wrapping your fingers around the seat stay or chain stay for leverage, the lever
does not leave a clear imp rint in the palm of your hand, and the serrations on the wheel fastener do not emboss the
surfaces of the dropouts, 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 Section, p. 18.
(8) If you disengaged the brake quick-release mechanism in 3. c. (2) 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 cl
ears the brake pads; then squeeze the brake lever and
make sure that the brakes are operating correctly.
B. Seat post cam action clamp
Some bik es ar e eq uipped with a cam acti on seat p ost bi nder. T he seat post cam acti on b inder works exactl y lik e the
traditional wheel cam action fastener (Section 4.A.2) 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 seat post (see fig. 8a).
WARNING: Riding with an improperly tightened seat post can allow the saddle to turn or move and cause you to
lose control and fall. Therefore:
1. Ask your dealer to help you make sure you know how to correctly clamp your seat post.
2. Understand and apply the correct technique for clamping your seat post.
3. Before you ride the bike, first check that the seat post is securely clamped.
