Do not use extreme ratios: smaller chainwheel linked to either of the
two smallest sprockets; larger chainwheel linked to any of the two largest
sprockets; central chainwheel linked to either the largest or the smallest
sprocket. These settings may cause both a lateral distorsion of the chain that
will impair the proper operation of the shifter and premature wear of the
drive components.
To improve performance when changing gears, follow the following
recommendations:
∙ When going uphill, use the gear combinations shown in Figure 1.
∙ When going up gentle slopes, or on the flat, use the gear combinations
shown in figure 2.
∙ When descending, use the gear combinations shown in figure 3.

Tyre pressure

Tyre pressure shall be as indicated on the tyre outside. Pressures are
stated in PSI or bar, with the maximum permissible value shown. Mind that 14
psi are equal to 1 bar and 1 bar = 1 kg/cm2. Underinflated tyres are more
subject to pinch flats (or "snakebites") and may cause damage to the rim.
Excessive tyre pressure may reduce the tread's ground adhesion.
Always change the tires when they reach their wear limit. A good tread
is essential to a comfortable ride and safe braking.

Replacement parts

To keep your bicycle in the best possible working condition and for your
safety, it is very important to only use original spare parts.
For better results and in order to
prevent damage to the drive system, it
is recommended that you should not
stress the pedals when shifting. So,
avoid shifting when making an effort
or riding uphill.
