ADJUSTMENTS AFTER SEVERAL HOURS’ USE Some parts of your bicycle will require slight modi cation after 2 to 3 hours’ use, mainly in order to make nal adjustments to the components. Derailleur cable tension is to be set: the housings will settle down, necessitating new derailleur and brake tensions.
REGULAR MAINTENANCE AND CHECKS Here is an idea of the type of maintenance to carry out on your bicycle, beginning at the date of purchase: how often you perform the maintenance may signi cantly increase if you use your bicycle intensively in hostile environments (mud, sand, water, etc).

Removing this type of wheel is di cult, so we recommend that you contact one of technical workshops. However, you will nd removal/replacement instructions in the speci c instructions supplied with your bicycle. IMPORTANT: Before using your bicycle, ensure that the wheel is correctly mounted.
USING QUICK-RELEASE SYSTEMS Quick-release maintains the wheels in position inside the frame and fork. For this to be e ective, it is necessary to set the adjusting nut (1) so as to produce a su cient closing force on the quick-release lever (2) of at least 12 daN (approximately 26,45 lb (12 kg)). To increase the closing force: turn the adjusting nut clockwise (anticlockwise to reduce the force).
1 – Using the brakes To slow the bicycle down or stop it: use the back brake rst and then lightly and gradually use the front brake. An overly rapid and excessive braking movement may cause the front wheel to jam and cause a dangerous fall.
