Specialized AFR S90 Bicycle Accessories User Manual

Install the front wheel and adjust the brake to allow the rotor to spin freely.5.
Adjust the headset to eliminate any free play, make sure that the fork rotates freely. 6.
Align the stem with the fork. Tighten the stem’s upper and lower steerer clamp
bolts in an alternating pattern. Increase torque in 5 in-lbf (0.56 N-m) increments.
Recommended torque applied to the steerer tube is 75 in-lbf (8.5 N-m). Refer to your
stem owner’s manual for specic torque spec recommendations for the stem bolts.
Damage to composite is difcult to visually identify. If the external composite surface
is dented, frayed, gouged, deeply scratched, fractured, chipped or otherwise
damaged, the component should be replaced. If a fork has suffered a crash or impact,
even if no damage is visible, Specialized or an Authorized Dealer should inspect the
product.
SHOCK PUMP
Specialized offers a shock pump, to add or release
air pressure from your Specialized fork. The Fox
shock pump is also recommended. Follow the steps
below:
Remove the air cap knob from the top of the right 1.
fork leg (Fig.3).
Thread the pump’s valve chuck onto the fork’s 2.
Schrader valve (holding the rebound knob so it
doesn’t turn) until pressure registers on the pump
gauge. Do not over tighten the valve chuck. If
there’s no pressure in the fork, no pressure will
register on the pump gauge.
Stroke the pump until you’ve reached the desired pressure (see air chart for pressure 3.
ranges). Pressure can be decreased by depressing the release valve button on the
pump body.
When the valve chuck is removed, air pressure will be released. This air is NOT from
the fork. It’s leftover air from the pump hose. When the pump is reattached to the
valve, pressure in the fork will decrease to ll the pump hose. This will lower pressure
approximately 10 PSI (i.e., a fork set at 100 PSI will show approximately 90 PSI when
the pump’s hose is re-installed on the fork, as the hose is relled by pressure in the
fork).
