6 Maintenance

huB BeARINGs

Hub bearings require special thin wrenches called cone
wrenches. If you do not own these tools, do not attempt hub
bearing adjustments. Have a qualified bicycle mechanic perform
the adjustment if you have any doubts.
❶ Check to make sure neither locknut is loose.
❷ To adjust, remove wheel from bicycle and loosen the locknut
on one side of the hub while holding the bearing cone on
the same side with a cone wrench.
❸ Rotate the adjusting cone as needed to eliminate free play.
❹ Re-tighten the locknut while holding the adjusting cone in
position.
❺ Re-check that the wheel can turn freely without excessive
side play.

INfLAtING the tIRe tuBe

WARNING!
• An unseated tire can rupture unexpectedly and cause
serious injury or death. Be sure the tire is properly seated
when inflating the tube.
• Over-inflation or inflating the tube too quickly may result
in the tire blowing off the rim and damaging the bicycle or
causing injury to the rider. Always use a hand pump to
inflate the tube. Do not use a gas station service pump to
inflate the tube.
Follow these steps to inflate a tire:
❶ Remove the valve cap and add air.
❷ Check the tire is evenly seated on the rim, both sides.
❸ Spin the wheel and check for high and low areas.
❹ Complete inflation to the recommended psi found on the
sidewall of the tire.
