Every bolt and nut mounted on the bikes has their specific torque value. This cannot be generalized for all bolts.
Normally every component brand indicates their recommended torque values. Nevertheless we indicate in the
below frame the standard torque values of every component.
WARNING: it is vital that the nuts and bolts are duly tightened. If you do not reach the adequate torque,
the component will move as a consequence. If you exceed the recommended torque you could possibly
force the screw thread which could lead to severe damage to the component. In other words, you will have
to respect the recommended torque value; otherwise you could suffer severe injuries.

2.2.1 Wheel check.
Lift up the front part of your bike and turn the wheel. Make sure that the wheel is running in a uniform circular
movement and does not make any lateral or vertical movements. You also need to check the pressure of the tyres.
The correct pressure is indicated on the side of the tyre. It is also very important to check the tension of the spokes
by simply touching them. All of them should be firm and tight.
WARNING: do never inflate a tyre with more than the maximum recommended pressure, indicated on the
side of the tyre. In case you exceed the maximum pressure, the tyre can get out of the rim which could
lead to severe damage on the bike and possible injuries to the rider and other persons who are close to
bike at that moment.
2.2.2 Brake check.
Make sure that the pads are placed inside the braking flanges of the rims. When the brake is in action the complete
pad surface should be supported on the rim. Neither the brake cables nor the hosing should have any
imperfection that could lead to any deficiencies. In case of disc brakes, it is very important to check that the pads
are not worn out and are supported completely on the disc. The brake lever should never touch the grip when it is
being used. Please note that while riding, due to the rider's weight and during a descent, it will be more difficult to
stop the bicycle.
