8.6. TESTING HANDLEBAR AND STEM 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 bolts tighter than before.
• 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.
• If the handlebar moves, loosen the bolts of the handlebar clamp.
• Put the handlebar in the correct position and tighten the bolts of the clamp tighter than before.
• Do this test again, until the handlebar does not move in the handlebar clamp.
See Torque Chart for Recommended Fastener Torque.
8.7. INSTALLING THE SEATPOST
WARNING: To prevent the seat coming loose and
possible loss of control, the “Minimum Insertion”
mark on the seatpost must be below the top of
the seat tube.
Seat and Seatpost Setup:
• Loosen bolt on Seatpost Collar so the Seat Post
can move freely.
• Ensure that the “Minimum Insertion” mark on the
Seatpost is below the top of the seat tube.
• Rotate the seat so it is aligned with the frame.
• Adjust the height of the seat to the desired riding
position. See “Adjust Your Saddle to a Comfortable
Height” for more information.
• Tighten Seatpost Collar bolt securely so it supports
the rider without moving.
