III. Tyres
Periodically check the tyre pressure. Riding with under or over-pressured tyres can reduce performance,
cause premature wear, deteriorations of the wheel rim, reduce autonomy or increase the risk of an
accident.
If significant wear or a tear is visible on one of the tyres, replace it before using the bicycle. A pressure
range is indicated on the tyre sidewall by the manufacturer and in the following table. The pressure
should be adjusted according to the user’s weight.
Method for determining the correct adjustment of the quick release mechanisms (wheel and seat clamp)
The quick release devices are designed to be operated by hand. Never use tools to lock or unlock the
mechanism so as not to damage it.
To adjust the clamping force of the wheel axle, you must use the adjusting nut and not the quick release
lever. If the lever can be manoeuvred with minimal manual pressure, it means that it is not tight enough.
You therefore need to tighten the adjustment nut. The quick release system must mark the fork legs
when closed in the locked position.
During each adjustment operation, check that the front wheel is properly centred with the fork. To set,
close, and open the quick-lock mechanisms, use the following method:
