and right while you hold the front wheel between your legs.
For your safety, adjust your handlebars so that you can easily access the brake levers and the shifters.
For mountain bikes: The shifters should be positioned in the prolongation of your forearms when you are in
riding position on the bike.
For road bikes: In general, the lower part of the handlebars should be horizontal.
WARNING: The stem has a minimum insertion mark ("STOP" or "INSERT MINI"). If this mark is visible, the stem may break,
causing potential injury, and the terms of the warranty will be cancelled. For threadless headsets, always make sure the
bolts are correctly tightened.
1.4 HEADSET
The headset is composed of two bearings and races placed at each end of the head tube. Lapierre bikes use
one of two types of headsets: classic (when the front fork, which has screw threads, is secured by a locknut),
or threadless (when the front fork is clamped by the handlebar stem itself and the play can be adjusted by
tightening the top cap).
TEST 1
During intense rides, the headset is put under a large amount of pressure, and afterwards you may notice
some play, which could make it difficult to steer. Riding with the headset not properly adjusted could cause
damage to your bike.
Here are two simple tests to perform before each ride:
TEST 1 – While applying the front brake, try to move the bike forwards and backwards. You will notice right away
if there is movement of the steer tube in the headset.
