2.2.4 Check the handlebar, stem and seatpost
Over time the condition of these parts could deteriorate due to impacts or simply because of usage.
It may be you find signs of fatigue and wear in these parts such as deformations or cracks in the
materials. If you do, you should immediately go to your Mondraker dealer to have them repaired or
replaced.
2.2.5 Regular checks of your bike
Every bike in general and its parts in particular have a useful life. Its length depends on the material
they are made of and how they are used and maintained. Using your bike in competition, at high
speed, carrying a lot of weight, going over very rough terrain, jumping or any other kind of aggressive
cycling reduces its useful life and increases the risk of breakdown or breakage. As a result Mondraker
suggests you carry out regular routine checks including the following:
CHECK BEFORE EVERY RIDE:
1. All bolts and nuts are tightened to the manufacturer's recommended torque value, in particular the
wheel quick releases.
2. Handlebar, stem and seatpost looking for visible damage or any cracks in them.
3. Front and rear brake systems.
4. Air pressure of the tyres.
5. Fastening of the grips on the handlebar.
6. Correct functioning of the fork and rear shock.
ADDITIONALLY ONCE A MONTH:
1. Welds of all tubes, links and all the moving parts of the frame looking for deep scratches, cracks or
deformation.
2. Operation of the front and rear derailleur.
3. Adjustment and play in the headset.
4. Travel and condition of the shift and brake cables and hydraulic tubes.
ADDITIONALLY ONCE A YEAR AT YOUR MONDRAKER DEALER:
1. Check the condition of the chain.
2. Adjustment and play of the bottom bracket cartridge.
3. Adjustment of the turn and bearings of the pedals.
4. Alignment and operation of the front and rear derailleur.
5. Handlebar, stem and seatpost.
6. Brake system, replacing cables or hydraulic tube if needed.
7. Alignment of the rims and tension of the spokes.
8. Condition of the tyres, replacing them if necessary.
9. Condition of the grips.
10. All the parts related to the rear suspension system.
11. Structure and functioning of the fork.
WARNING: Do not ride a bicycle or component with any crack, bulge or dent, even a small
one. Riding a cracked frame, fork or component could lead to complete failure and falling,
with risk of serious injury or death.
WARNING: Bicycles and their accessories are designed for aggressive use but do have their
limitations. Exceeding these limitations could lead to breakdown or breakage with serious
consequences for the rider.
