8.5.4 Maintaining the stem
Incorrectly fastened screws may come loose due
to impact. The stem may no longer be firmly fixed
in its position as a result. This will cause a crash
with injuries.

Check the handlebars and the stem’s quick
release are firmly in position.

8.5.5.1 Adjusting the hub with cone bearing

bearing shell fixed in the hub cone body rotates
with its larger ball bearing surfaces around the
inner bearing cone resting against the fork end.
The outer bearing shell rotating around the
stationary bearing cone is subject to considerably
more evenly distributed loads thanks to its larger
ball running surface.
