wash them with soap and water. Rinse and allow to air dry.
Every week, make sure there are no loose, damaged or broken spokes. If a wheel is not in good
condition, the efficacy of the brakes and the rigidity of the set will be severely reduced.
WARNING An improperly adjusted hub could cause you to lose control and fall. Carefully ins-
pect the hub system before each ride, and do not use the bike until any problem that may arise
during the inspection has been resolved.
Once a month, check that the front and rear hubs are well adjusted. Lift the front wheel and try
to move the rim from left to right. Watch and feel for any play in the rim. Spin the wheel and
listen for any strange sounds in the movement. If the hub appears to be loose or makes strange
noises, the hub will need to be adjusted. Repeat this process with the rear wheel.
Every month, check the wear of your rims. In some adult bicycles, there are indicators for wear
on the braking surface. If the rim is so worn that you cannot see the wear indicators, the rim
change should be performed by your authorized dealer.
Before installing the rim, make sure the rim tape is installed, so that the spoke nipples or ends
do not puncture the inner tube.
WARNING Make sure the rim tape covers all spoke ends and nipples. If any are left uncovered
and puncture the inner tube, the wheel will lose pressure suddenly, making you lose control and
fall.
Adjustment
Adjusting the front hub
This procedure requires specific materials and know-how. Therefore, it should only be perfor-
med by an authorized dealer.
Adjusting the quick-release mechanism
To properly and safely adjust the quick-release mechanism, carefully read and follow the instruc-
tions below.
- Turn the lever of the quick-release to the Open position, and insert the wheel in the blades of
the bike and make sure the axle is securely positioned.
- Now move the lever to 45 and tighten the quick-release bolt clockwise with your hand until you
cannot turn it anymore.
- Move the lever to the tightening position. Once closed, it should be in the Closed position as
shown in the upper left figure.
Do not tighten the quick-release as if it were a bolt; the attachment will not be tight enough to
keep the wheel in position.
WARNING A quick-release that is not properly adjusted could cause the wheel to loosen or fall
out unexpectedly, and cause you to lose control or possibly fall. Be sure that the quick-release is
correctly adjusted and closed before using the bicycle.
- If the lever can be easily moved to the Open position (less than 50 Newton), that means that
the fastening force is insufficient. In this case, re-tighten the quick-release bolt clockwise and
turn the lever to the Closed position. If the force needed to turn the lever is excessive (more
than 200 Newton) repeat the operation above but loosening the bolt counterclockwise. Repeat
these operations as many times as needed until you find the optimum fastening force.
- The quick-release should be oriented in such a way that it does not interfere with other bike
accessories.
- If the quick-release mechanism fails, take your bike to your authorized dealer.
Checking the quick-release mechanism adjustment
- Lift your bike and strike the upper part of the wheel. The wheel should not drop out, loosen or
move from side to side.
- Make sure the quick-release lever cannot rotate in parallel with the tire.
- If you need more than 200 N force to close the quick-release, it is too tight and you must
readjust it.
- If you need less than 53 N to close the quick-release, it is too weak and you must readjust it.
Adjusting with bolts
- Install the wheel into the blades (of the frame or fork) and make sure the axle is securely inside
the slots.
