Testing Stem and Handlebar Tightness
To test the tightness of the stem:
• Straddle the front wheel between your legs.
• Try to turn the front wheel by turning the handlebar.
• If the handlebar and stem turn without turning the front wheel, realign the stem with
the wheel and tighten the stem bolt(s) tighter than before (about 1/2 revolution only at
a time).
• Do this test again, until the handlebar and stem do not turn without
turning the front wheel.
To test the tightness of the handlebar clamp:
• Hold the bicycle stationary and try to move the ends of the
handlebar up and down or forward and back.
WARNING
• If the handlebar moves, loosen the bolt(s) of the handlebar
clamp.
• Put the handlebar in the correct position and tighten the
bolt(s) of the handlebar clamp tighter than before.
• If the handlebar clamp has more than one bolt, tighten the
bolts equally.
• Do this test again, until the handlebar does not move in the
handlebar clamp.
