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.

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

adjusted by tightening the top cap).
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.
