FIRST SECTION

I Setting the riding position and safety"
1. Ensure that the bicycle is the right size
A bicycle that is too big or two small for riding is difficult to control and may be
uncomfortable.
Size of the frame (one inch = 25,4mm):
To check if the size of the bicycle is correct, just get on it and put your hands on
the handlebars. If your crotch touches the frame, the bicycle is too big for you.
There should be between one and two inches between your crotch and the frame.

For your safety, the saddle
should not be raised above
the marker on the seat post.
• Mountain bike/Hybrid/town bike
For a good pedalling position, set your saddle height so
that with your leg extended your heel rests on the pedal (in
the lowest position)
Therefore, when pedalling your leg will be slightly bent at
the lowest point so that your hips do not sway and for easy
pedalling.
Rapid seat pin blocking will make tightening easier
To tighten, place the lever at 90°, completely hand tighten
the screw and pull the lever down. The force used should be
sufficient to block the seat pin.

DECATHLON ADVICE :
• Using a mountain bike, your saddle will be set in a high position when you are
on flat or rising ground to increase your pedalling power. However, going
downhill, to better control your bike, lower at the saddle so you can recover
your route by putting your feet on the ground.
• To set the saddle recoil: sat on the saddle, feet in the pedals (conventional or
automatic), the swivel joint should be perpendicular to the pedal spindle when
the crank is horizontal.
Multiply the crotch value by 0.88 to obtain
your seat height, the distance separating
the centre of your pedal above your seat,
that you will set parallel to
the ground.
